***** It often takes decades for regular medicine to pass control and be introduced to the population at large. Making deliberate changes to our DNA would first of all need to be practically possible, and then the changes need to be tested for safety, which is difficult and utterly unethical, unless we're talking about mass scale voluntary gene therapy. A fake public vaccination program would not be possible, because such secrets cannot be contained. And if exposed, would set back humanitarian efforts for ages to come.
***** Humans, having gone through a recent (in evolutionary terms) bottleneck event, are very similar across the whole species. So there isn't *that* much genetic variation to choose between. Attractiveness, youth, tallness, strength and smarts have always been boons for getting chosen as mate. These are general traits of genetic health and access to resources.
***** I was unaware that gene therapy had been done on humans. Interesting, I'll have to check up on that. Anyway, there are 7 billion people on the planet. What you're talking about is a drop in the ocean.
tommy tran same here. wont be there, when the first city on mars gets build. makes me sad and angry to know, that people in ~200 yes might get the chance to life forever while billions had to die so they could be lucky to be born in that time
tommy tran if dont know we might be able to upgrade ourselvs not only in age also Musluse brain and prety much evry thing proboly in 30 years that will start
Dixie, you should read TIME PRESSURE. Novel written in the 80's about a woman from the future discovered by some hippy dude in the late 70's... Pretty good, especially the ending about the MINDDD
My hypothesis for human evolution: - humans are becoming more handsome - humans are becoming smarter - humans will lose their animal instincts (e.g. fight/flight reaction, instinctive fear of snakes and other dangerous animals...etc.) - i also believe that males will lose their strength as it isn't necessary anymore
Eugene Khutoryansky ok. why is this important? that info fell into the trivia section for me. it makes sense yes, but why are you glad he brought it up? sounds a bit like "iam a vegetarian and this supports my lifestyle, so iam on the right side and if we reach that people threshhold, everybody needs to become like me" not that anything is bad about that lifestyle but i would push a "youre wrong!" button in the face of a vegetarian
Pseudonym Persona The American Dietetic Association's position paper on vegetarian diets states: "Well-planned vegan and other types of vegetarian diets are appropriate for all stages of the life cycle, including during pregnancy, lactation, infancy, childhood, and adolescence. Vegetarians have been reported to have lower body mass indices than nonvegetarians, as well as lower rates of death from ischemic heart disease; vegetarians also show lower blood cholesterol levels; lower blood pressure; and lower rates of hypertension, type 2 diabetes, and prostate and colon cancer."
We couldn't adapt to less oxygen. it's impossible unless we were rebuilt atom by atom to live without oxygen. We would also be darker since Mars doesn't have as strong of atmosphere to reflect uv rays . darker skin helps deflect uv rays .
***** we will adapt to less oxygen on mars because it's pretty obvious that mars has less oxygen and I think if we lower the amount of oxygen in space suits over time that we will become used to it when we are outside of the bubbles we create on mars.
I honestly don't think we will evolve in a physical sense at all, but rather metaphysical. The reason for this is because we have reached a near perfect hardy- Weinberg principle in developed nations. What this means is that anyone is able to reproduce now, with more people looking less at physical features and needing to survive in nature, but rather how to survive in the economy, so how we socially interact would be the evolutionary benefit. Evolution to cause a change or speciation requires natural selection. So unless something drastically changes our way of life, we won't need to physically change
Urban Nomad How old are you bro? I'm almost 16 and born in 2000 so I'm probably still gonna be here by the time the population has gone up by 2 billion.
I just don't get why do people need to do all of this. Robots are pointless, in my eyes. And they would eventually try and kill us.. GMO is also unnecessary, cuz we got deliberate selection. Just sayn.. :D Atleast we can still turn back and make the situation better.
fakeaccount8888 Agree. But if they make self-driving cars, there would be people who would hack into their networks and try and steer them off of cliffs. :D
You helped bring a realization to me: the genetic modification of humans might not just provide health benefits for all people making us more alike, it may also encourage divergence; some people may be modified for particular tasks, and other people may be modified more-so for other tasks; that idea could seem a little scary right now anyways.
***** Yes but we are humans. Significant change can't happen for humans in 50 years, as most people live to be around 80 years old. In 50 years, we will be only 1 or 2 generations down the line. We aren't going to have humans be different enough to notice in one generation.
my guess for human evolution is: engineered evolution, humans who control their own dna to adapt to their needs. for example athletes will be made stronger and faster through tech. less illness, smarter, but naturally weaker because we rely on technology for everything
+Anun Kash Earth is too far away for it to be in danger from solar flares.The most that solar flares large enough to have any effect on the Earth can do, is temporarily interfere with cell-phone reception a bit. And it's pretty rare for them to reach far enough to have even THAT much effect.
Cheshire Kat i'm pretty sure its possible for the sun to do something to wipe out communication. i have no evidence to this, just pretty sure i've heard it somewhere reputable.
Because no one can see catastrophe. Antibiotics are losing their effectiveness, and once European countries stop being able to help the third world countries, their mortality rates will skyrocket, thus the population will not keep on growing into perpetuity.
That why wars, disease are there for, who knows in the future there might be a disease that wipes out almost all humans leaving only a couple of millions left, or nuclear war
Loving the show! Minor criticism, I'd love for you to add more interactive editing, right now, it's too plain. For example, add pictures when he talked about the artist's pictures.
Exactly... The only thing currently that makes us evolve is how many children do certain kind of people have... Sadly the more knowledgeable is someone the less children they have... Sadly, we get more and more people that are dumb year after year...
+Samsung Galaxy well, I did, but for me it was nothing new, I live in a region where it is quite visible, those who can't support even 1 kid have 3-4+ sometimes even 8, while those who could support 5-10 have 0-1 children... The first group rarely have more than 4-8 years in school while the, other has 1-2 college degree... Btw idiocracy started decent, but by the middle it became the thing it was speaking against, dumb, really dumb...
+Tennic It does. You see, if everybody has rights to, lets say, vaccines, than natural selection is destroyed. If everyone has access to water, food and shelter without having to do a damn thing to EARN it, than it KILLS natural selection. Understand ??
It's too difficult to predict. There are some technologies on the horizon that will affect every single aspect of our life once they are realized. For example, if Lockheed Martin is able to create a fusion reactor, as they have stated will happen within the next few years, then energy becomes much less of a concern. If energy is no longer a concern then automation accelerates even faster and transportation, manufacturing, and many services drop to near-zero marginal cost. This is just a single company with a single technology. There are dozens of other projects being worked on this very moment that could have just as big of an impact as this one. The next 50 years is going to be very interesting because it's going to shatter entrenched ideas we have had for over a century about how society and the global community should work. In the same way the Internet changed the way we access, store, and interact with information. So will the next wave of technology change the way we think about and interact with the physical world and each other.
if you notice, u can see a trend, which is, human in the old ages walked alot, they did hunt run etc (exterior activities) requiring alot of energy. and humans are slowly becoming more in house. for example young people less and less hang out, they are staying at home, connected to internet, so trend is becoming more and more at home, and more and more connected. and we are starting now to see those VR glasses where u dont even have to move your body to explore other places, so i suspect the next human revolution will be completely digital, you connect to the "network" and dont get out of the machine. your job will be there, doing digital jobs etc... eventually human will evolve to connect directly to the network brain and machine into a "One entity" gathering all the brains power into a huge powerful machine able to solve huge problems. and eventually, we humans will be able to create just the thinking part of the brain without the rest of the body, which means, it will transpose human consciousness into the network itself, being just energy, a consciousnesses energy, that can jump from device to device, planet to planet, at light speed... think about this, because that is the thing...
but im not a kid, i just observe the trend, that is a fact. why do u think alien dont come here alot?, because they too discovered that experience can be better and augmented when you go virtual, so maybe they are living and comunicating in their world virtual, and really dont explore the world in flesh... it would be safer for them to create a drone and then control the drone (ufo) with their VR glasses and everyone could watch the probe exploring the deep space.... at the same time... its Faster safer, makes no sense send real living creatures into an unknown place?! that you dont know when to return. This way you dont need to think about Living conditions on the spacecraft, nor food , no danger, no radiation, no death... less space, higher speeds (which a body could not resist)... if in the end all it matters is to control the spacecraft and see what it sees through its high resolution multi spectrum camera sensors... just think about it! One can do everything remotely, we humans are very primitive because we think we need to go there. Like ocean explorer in boats, which is stupid non sense, if you have tech...But as a last resource we could anyway build a robot that could have full movement freedom and be a surrogate for the remote controller, thing is our tech is not yet there to do it... but it is possible. I believe that how a higher civilization does it... they send probes millions to every space location, and they watch it remotely, on their 3D VR System...
I think so. And today probably we are living in a computer simulation generated by our descendants. I think the aliens are our descendants. Humans after 300 or 500 or 1000 years. As we know technology evolution is exponential. You can see what is done in the last 100 years. So imagine in 300 or 500 years.
ML8593wy Thats what im talking about, there are going to be too many humans for us to feed, we have 4.5 billion acres in our planet, and we require 3.5 acres to feed only 1 human, even if it required 1 it wouldnt be enough since we got over the limit of population. We are still alive since the food is not distribuited that fair. Either billions of humas are going to die or we could build acres underground
I'm vegetarian and I hope to raise my children as a vegetarian as well (if they choose to not be vegetarian when they're older is fine with me) there is one more benefit to being vegetarian that I hadn't originally thought of, the population of people on earth. These videos are awesome, nice to learn something new from videos like these~
We might get the tale back, or we could lose the human head, and get the head of a chicken. We could go back to being bacteria in 50 years or we could just become poop, and live as poop for about a billion years... That could be the next step in human evolutionism.
I've just started looking into this, and my first thoughts are: Economic inequality will create genetic divergence; this is already happening and the results are appalling. Assuming we survive the next century or two, I reckon we'll be choosing health, beauty and longevity. As for population levels and space travel, I think a lot of people have yet to learn we can't survive without a diversity of other species in a natural biosphere, so we can't take up all the space on Earth. Also, the problems of physically travelling light years away are so great that I think we'll probably find that our consciousness is more likely to leave Earth, not our biological bodies.
Bigger heads and eyes oh my god I have a theory aliens are actually is from the future guys we are alians and the aliens we find our us from the future and one day we will be aliens and go back in time to shape humanity
I was thinking: Wouldn't human evolution stop because of our technology? Because of our technology, the human body doesn't have to adapt to new environments, but rather, our technology would have to adapt. For example, Trace said that human eyes will possibly get larger because it's going to be darker (under water), but wouldn't humans just create new technology that would create a brighter environment (a better lamp or something in that nature) And so on
What about disease? Humanity has become quite good at developing medicaments to counter diseases that would kill you wuite early in your life. That would mean, that we pass on the "faulty" DNA, that would have sorted out itself without treatment, right?
+Schmudli We would be kind of equal with ordinary animals. Using dozens of tools is part of humanity, like human body doesn't produce vitamin C, you could have call it faulty DNA as well. Also what we percieve as "faulty" DNA can in next few generations combine to create precious DNA, you never know.
Kids these days and their crazy hair genes. Well back in my day we had night vision, which helped us walk to school up hill both ways in the snow at night. Those were the days.
Love your videos on this channel or on TestTube, even DNews ( but your barley even there ;( ) But almost 7 Billion people? There around 7,300,000,000 humans alive I think.
klondike444 Nobody is infallible. And I for one, think that Trace is doing great working with notes alone, as opposed to the prompter he's used to on DNews or TestTube. I'm sure he; or one of the editors, can annotate corrections.
+Sun Beam Who knows, technology will play a big role. And that didn't lift off the ground till about 100yrs ago. And didn't start really booming till the start of the new century which was only like 15yrs ago. I definitely do not agree with looking different in 50yrs. But 500 is definitely possible.
a lot of humans will die if we migrate to space.. but maybe we should for a little while, just to thin us out so we dont continue to multiply exponentially and destroy the earth
You should do a video on Service dogs. That's always amazed me. There's dogs for PTSD, the blind, Cystic Fibrosis, etc. What makes these dogs so smart?
Im going to disagree. Us humans havent evolved for such a long time because we dont need to any more. Because we stopped adapting to the environment, and started to make the environment adapt to us. We built houses, heating, farms, all this to fit our needs and make it as comfortable and as easy as possible. The same will happen when we decide to live under the ocean or in space. before doing that we will create artificial replacements for thing we need to survive, like gravity or a sun. Our space crafts will be suited to have us live in it comfortably. There for we wont evolve because there will be no advantage for any one who is born different, since environment we made is designed to suit the average human.
raphael normie wrong on the first point, evolution through natural selection is an on going process, it doesn't stop we have & are still evolving, genetic modification aka "designer babies" is the next big thing I think, I mean look at plastic surgery industry & the lengths people will go to just to change themselves physically now combine that with the current/future knowledge of genetics & our growing dependences on technology.
I didn't mean that mutations would stop happening. Rather that any new mutations in humans aren't going to have any mager advantage if not any over any one else because of the fact that we changed the environment to suit the average human.
Its more about common sense. Think about it. How does evolution work? It happens when there is a mutation, and that what makes it different gives it a better advantage of surviving over the others. And when it mates, its new geens will exsist in its children. And it continues on and on and on. You end up having an off spring that can survive better. Now look at humans, then look at human homes, cities, tools, ect... (and medicine and safty in our territory allows us to live longer with less danger). its all designed by humans to suit humans. So if you have a mutation of a human that could run faster, or would be stronger, or smarter. He isnt going to have a advantage of survival over every one else. Because in a human environment, every one is safe. There is no competition in survival.
I like how these guy presents himself because he just tells you like it is not like he is trying to force his opinion on you and his views like most ppl do on youtube channels that cover stuff like this.
Homo Spaceian! Interesting, I forget to include popular trends and cultural fad changes in thinking about the future. Its worth noting that throughout history, the amount of time b/w paradime shift has gotten shorter and shorter. It use to be 1000s then 100s of years before humans made leaps...now its decades.
Trace, Ive really gotten into Test Tube News recently. I like the concise and informative information. However, regarding Test Tube Plus, it may be nice to see video inserts and switching between shots of you sitting at the table to documentary style footage. Just a thought. Keep up the good work.
i love how long but short this video is, it would help if you could show us some pictures or visualizations of some things you mention to help my imagination :)
Yes, you can feed more people on a vegetarian diet, because vegetables are more plentiful and easily produced than livestock. However, it was our consumption of cooked meats that gave our brains the initial kick to begin evolving to its modern day level. With a diet of grains, fruits and vegetables, along with a balance of lean meats if you so choose, whether it be fish, poultry, or even lean beef, we could pretty much feed the world.
I was 21 years old 50 years ago. We humans have not changed but our standard of living is much, much better now. Technology has made life very easy for us in comparison to what it was 50 years ago. TV, air conditioning, sneakers, permanent press fabrics, washer & dryers and other appliances. Cheap and very abundant food. Now, because of computers and the Internet we have access to information to a degree never before seen by the human race. Even with all the problems that our world faces we still live in the best of all times.
Isn't funny listening to people who lack the life experience, or patience to crack open a history channel talk about how "horrible" things are now! Between many countries experiencing more peace than ever before, the technological developments and access to information are unparalleled! I'm one of the few who's anticipating the future with a modicum of optimism.
In the vein of evolution just a quick question: how does the initial evolution begin. Random genetic mutations? So for an example snakes prior to developing venom in their evolutionary history to the present? What factors presented themselves that forced that change to develop a venom sac gland? Were there just trillions of mutations and the species that developed the gland survived and the rest died off?
I really love this show as it is, but I wonder what it would be like in a podcast format. I feel like the show as a whole might flow a little easier if Trace had someone to talk with about these topics, maybe someone who resembles the viewer in that they are learning the information for the first time from Trace. Either way I'll keep watching though :)
What if the idea of aliens (with small bodies, large heads and big eyes), are actually a future representation of what we are to become? Could we look so 'alien' to ourselves?
This is just something I've thought of for the past few years, because natural selection affects humans far less than it used to (Im primarily referring to those living in first world countries) human evolution will be fairly different to that of other animals. The strong, attractive, intelligent will breed with the strong, attractive, and intelligent, while the ugly, weak, and unintelligent will breed with the ugly, weak, and unintelligent, while in normal circumstances the weaker animals would die out, in the case of humans they live on and pass their genes on. This will result in two different types of humans, as thousands of years from now, the gap between the intelligent and the unintelligent, the strong and the weak, and the attractive and the unattractive will grow to much higher levels, creating what would seem like almost different species eventually.
I don't want to criticize too harshly but... It started off with "50 years from now" and then kinda jumped to warp-factor 5 into the future. My thoughts are - "If you want to get to the stars, leave the meat behind". Think of evolving into a non-corporeal consciousness. You'll go a lot farther and much much faster.
It seems far, far more likely that we will merge with our technology (a.k.a., H+) as a form of adaptation rather than suffer the long, hard evolutionary process through genetic selection. Advanced in computing, power systems, prosthetics, etc., all are leading is in this direction.
I think that in some ways modern medicine and medical breakthroughs are kind of interfering with natural selection and evolution because those who are not necessarily "the fittest" can still survive and reproduce.
self-transformation is are ultimate next step . The end result is when we resemble small universes contents "if the black holes don't suck us up first" which might tell us where we came from lol .
Just an Evolutionary Biology Master dropping by to nitpick: Some of the stuff here is overly simplified. First of all, human populations are too large and intermingled nowadays to allow new mutations to manifest in the majority population purely because they're more successful. It's called the founder effect, and since we inferior beings are here first, we will likely out-compete even clearly superior mutations due to population processes. Evolution doesn't mean that droves of inferior humans will DIE from selection. We're only just beginning to understand gene processes, but all organisms have genes that toggle on or off due to environmental factors, and this may bring rise to subsequent, more beneficial mutations. A population may evolve, while keeping the majority of its individuals contributing to its gene pool - they don't have to mostly die off; that's way too oversimplified sensationalism. What will people look like in the future? Depending on the environmental factors, we may become shorter due to a tolerance for growth hormones in meat, and to prevent back problems. We will definitely be more intermingled, making more people share a mixed heritage. And despite the stark difference in appearance over a short time, surprisingly few of the changes will have been brought about by actual mutations.
The trouble with modern evolution is that mankind's technical expertise has trumped natural selection. For example, there's a study that shows human eye sight is actually getting *_worse_*, because we developed glasses/contact lenses to correct bad vision. So you go through life with your bad vision corrected artificially, but naturally, you still have bad vision. This bad vision is passed on to your offspring, who in turn, have bad, if not worse vision that's also compensated for with corrective lenses. They then pass their worse vision onto the next generation, etc. So if anything, mankind's vision will become non-existent before it adapts to the darkness of space. Other changes might be our feet - the soles of our feet may get weaker and weaker overtime since we protect them now from the elements with shoes. We keep other problems like high blood sugar, diabetes, kidney stones, epilepsy, etc all in check with medications. These ailments aren't CURED or REMOVED, they're just "controlled" to such a degree that their affect on our daily lives is minimal. Thus, these ailments too, will be passed on to generation to generation, and will worsen each time, unless a generation can develop a permanent solution that means they won't pass the ailment on to their offspring. In summary, mankind's ingenuity (which ironically, developed via evolution) has now backfired on us, because we're at a point of no return where each generation is more and more dependent on our ingenuity to control ailments/defects than the last (rather than letting evolution run it's course and weed the ailments out of the species), because each generation is plagued with more than the last. Eventually, we will reach a point where every aspect of our existence has become compromised, and must be "corrected" by one form or another. Don't want to sound tin-hatted, but sounds like we're on the fast track to something comparable to the Borg or the Cybermen, with our bodies chiefly mechanical and only basic biological components like brains remaining.
Not trying to be disrespectful, but a serious question: Who are test-tube and Trace, and why should we listen to them? Just curious what the sources are, because they say a lot of stuff, and while it's very cool and interesting, some sources of information would be nice. Where do they get their information, and what are their credentials?
I actually really like this channel's community. Seems like for the most part people are actually discussing things and not trolling. Love this week's topic btw.

Evolution to cause a change or speciation requires natural selection. So unless something drastically changes our way of life, we won't need to physically change

When population reaches 30 billion.
let the hunger games begin..
XD
I'm glad I won't be in here lmao
Urban Nomad How old are you bro? I'm almost 16 and born in 2000 so I'm probably still gonna be here by the time the population has gone up by 2 billion.
why is the population bomb so taboo?
the hunger games won't do shit, only 23 people die every YEAR, we need alot more than that to bring down the population.

Exactly what I thought
what's next? cat ears and a tail?

+Troll King well humans used to have a tail

I hope humans won't screw up their genes in the future...
I think that might happen that's the sad
Brendan Raymond I think cancer would increase because of the uses of gene therapy using retro viruses and stuff
LinardBraslin nature already did it.
I just don't get why do people need to do all of this. Robots are pointless, in my eyes. And they would eventually try and kill us.. GMO is also unnecessary, cuz we got deliberate selection. Just sayn.. :D Atleast we can still turn back and make the situation better.
fakeaccount8888
Agree. But if they make self-driving cars, there would be people who would hack into their networks and try and steer them off of cliffs. :D
You helped bring a realization to me: the genetic modification of humans might not just provide health benefits for all people making us more alike, it may also encourage divergence; some people may be modified for particular tasks, and other people may be modified more-so for other tasks; that idea could seem a little scary right now anyways.

Um, am I the only one that thinks this is a stupid question? We didn't change for hundreds of years, so why would we change in the next 50?
***** Yes but we are humans. Significant change can't happen for humans in 50 years, as most people live to be around 80 years old. In 50 years, we will be only 1 or 2 generations down the line. We aren't going to have humans be different enough to notice in one generation.

my guess for human evolution is:
engineered evolution, humans who control their own dna to adapt to their needs. for example athletes will be made stronger and faster through tech.
less illness, smarter, but naturally weaker because we rely on technology for everything
+joealtair3000 so the first massive solar flare that comes through...
+Anun Kash Earth is too far away for it to be in danger from solar flares.The most that solar flares large enough to have any effect on the Earth can do, is temporarily interfere with cell-phone reception a bit. And it's pretty rare for them to reach far enough to have even THAT much effect.
Cheshire Kat i'm pretty sure its possible for the sun to do something to wipe out communication.
i have no evidence to this, just pretty sure i've heard it somewhere reputable.
+Anun Kash there is another billion years before the sun becomes to close to the earth by then we would have left
Naa m8

Actually the sun has an estimated 5-6 billion years left.

I've been watching these videos all day! "TestTube Sunday"
Love this channel, seems better fit for a podcast though. Personally, I'd love a Test tube/ Dnews podcast
we......we're.........we're the aliens....
....yup
.........ok.....
ow
I had sex with 6 different aliens

So, in 20 years, the Earth will be at maximum capacity.... He doesnt seem very freaked out... none of us do...WHY IS THAT
Most people of the old generation will be dead by then, and us, of this generation dont like to think of, the what if. So we are basically screwed....
I wonder Thomas.....10 billion people living in your house! Mwahahaha
if you think the earth will be maxed out in 20 years? Bless your heart.
Because no one can see catastrophe. Antibiotics are losing their effectiveness, and once European countries stop being able to help the third world countries, their mortality rates will skyrocket, thus the population will not keep on growing into perpetuity.
That why wars, disease are there for, who knows in the future there might be a disease that wipes out almost all humans leaving only a couple of millions left, or nuclear war
Loving the show! Minor criticism, I'd love for you to add more interactive editing, right now, it's too plain. For example, add pictures when he talked about the artist's pictures.
How can we evolute? Nobody will die, we have science technology and medicine.
Exactly... The only thing currently that makes us evolve is how many children do certain kind of people have... Sadly the more knowledgeable is someone the less children they have... Sadly, we get more and more people that are dumb year after year...
+Dhrazer ...You watched Idiocracy, yes ??
+Samsung Galaxy well, I did, but for me it was nothing new, I live in a region where it is quite visible, those who can't support even 1 kid have 3-4+ sometimes even 8, while those who could support 5-10 have 0-1 children... The first group rarely have more than 4-8 years in school while the, other has 1-2 college degree... Btw idiocracy started decent, but by the middle it became the thing it was speaking against, dumb, really dumb...
+Yu Ying death has nothing to do with evolution. the only thing that evolution requires is giving birth. evolution would still happen without death.
+Tennic It does. You see, if everybody has rights to, lets say, vaccines, than natural selection is destroyed. If everyone has access to water, food and shelter without having to do a damn thing to EARN it, than it KILLS natural selection. Understand ??
It's too difficult to predict. There are some technologies on the horizon that will affect every single aspect of our life once they are realized. For example, if Lockheed Martin is able to create a fusion reactor, as they have stated will happen within the next few years, then energy becomes much less of a concern. If energy is no longer a concern then automation accelerates even faster and transportation, manufacturing, and many services drop to near-zero marginal cost. This is just a single company with a single technology. There are dozens of other projects being worked on this very moment that could have just as big of an impact as this one. The next 50 years is going to be very interesting because it's going to shatter entrenched ideas we have had for over a century about how society and the global community should work. In the same way the Internet changed the way we access, store, and interact with information. So will the next wave of technology change the way we think about and interact with the physical world and each other.
Shaun Shull Agreed

if you notice, u can see a trend, which is, human in the old ages walked alot, they did hunt run etc (exterior activities) requiring alot of energy. and humans are slowly becoming more in house. for example young people less and less hang out, they are staying at home, connected to internet, so trend is becoming more and more at home, and more and more connected. and we are starting now to see those VR glasses where u dont even have to move your body to explore other places, so i suspect the next human revolution will be completely digital, you connect to the "network" and dont get out of the machine. your job will be there, doing digital jobs etc... eventually human will evolve to connect directly to the network brain and machine into a "One entity" gathering all the brains power into a huge powerful machine able to solve huge problems. and eventually, we humans will be able to create just the thinking part of the brain without the rest of the body, which means, it will transpose human consciousness into the network itself, being just energy, a consciousnesses energy, that can jump from device to device, planet to planet, at light speed... think about this, because that is the thing...
MiKe QZ I like your imagination. Reminds me when I was 7
but im not a kid, i just observe the trend, that is a fact. why do u think alien dont come here alot?, because they too discovered that experience can be better and augmented when you go virtual, so maybe they are living and comunicating in their world virtual, and really dont explore the world in flesh... it would be safer for them to create a drone and then control the drone (ufo) with their VR glasses and everyone could watch the probe exploring the deep space.... at the same time... its Faster safer, makes no sense send real living creatures into an unknown place?! that you dont know when to return. This way you dont need to think about Living conditions on the spacecraft, nor food , no danger, no radiation, no death... less space, higher speeds (which a body could not resist)... if in the end all it matters is to control the spacecraft and see what it sees through its high resolution multi spectrum camera sensors... just think about it! One can do everything remotely, we humans are very primitive because we think we need to go there. Like ocean explorer in boats, which is stupid non sense, if you have tech...But as a last resource we could anyway build a robot that could have full movement freedom and be a surrogate for the remote controller, thing is our tech is not yet there to do it... but it is possible. I believe that how a higher civilization does it... they send probes millions to every space location, and they watch it remotely, on their 3D VR System...
Ever heard about generation fit?
I think so. And today probably we are living in a computer simulation generated by our descendants. I think the aliens are our descendants.
Humans after 300 or 500 or 1000 years.
As we know technology evolution is exponential.
You can see what is done in the last 100 years. So imagine in 300 or 500 years.

ᅚ
The sun will still shine in two hundred years and she's the source of all resources we need.
ML8593wy Thats what im talking about, there are going to be too many humans for us to feed, we have 4.5 billion acres in our planet, and we require 3.5 acres to feed only 1 human, even if it required 1 it wouldnt be enough since we got over the limit of population. We are still alive since the food is not distribuited that fair. Either billions of humas are going to die or we could build acres underground
I'm vegetarian and I hope to raise my children as a vegetarian as well (if they choose to not be vegetarian when they're older is fine with me) there is one more benefit to being vegetarian that I hadn't originally thought of, the population of people on earth. These videos are awesome, nice to learn something new from videos like these~
We might get the tale back, or we could lose the human head, and get the head of a chicken. We could go back to being bacteria in 50 years or we could just become poop, and live as poop for about a billion years... That could be the next step in human evolutionism.
Not in 50 years..

"Aliens" with the big heads, big eyes, 3-4 fingers and slender bodies that we know today are actually our descendants who have traveled back in time.

krraman666 "....they'll be no accusations...just friendly crustaceans, under the Seeeeaaaaa...."
I've just started looking into this, and my first thoughts are:
Economic inequality will create genetic divergence; this is already happening and the results are appalling.
Assuming we survive the next century or two, I reckon we'll be choosing health, beauty and longevity.
As for population levels and space travel, I think a lot of people have yet to learn we can't survive without a diversity of other species in a natural biosphere, so we can't take up all the space on Earth. Also, the problems of physically travelling light years away are so great that I think we'll probably find that our consciousness is more likely to leave Earth, not our biological bodies.
Bigger heads and eyes oh my god I have a theory aliens are actually is from the future guys we are alians and the aliens we find our us from the future and one day we will be aliens and go back in time to shape humanity
😂😂😂 awesome..
I look/listen do you everyday Trace. Love the show, keep up the good work.
I'll be back in 50 years to tell you
Thomas Dank engine lol
I was thinking: Wouldn't human evolution stop because of our technology? Because of our technology, the human body doesn't have to adapt to new environments, but rather, our technology would have to adapt. For example, Trace said that human eyes will possibly get larger because it's going to be darker (under water), but wouldn't humans just create new technology that would create a brighter environment (a better lamp or something in that nature) And so on
This guy is awesome.
where can I listen to the full podcast instead of parts??
What about disease?
Humanity has become quite good at developing medicaments to counter diseases that would kill you wuite early in your life. That would mean, that we pass on the "faulty" DNA, that would have sorted out itself without treatment, right?
quite*
+Schmudli yes, quite
+Schmudli We would be kind of equal with ordinary animals. Using dozens of tools is part of humanity, like human body doesn't produce vitamin C, you could have call it faulty DNA as well. Also what we percieve as "faulty" DNA can in next few generations combine to create precious DNA, you never know.
Schmudli, intresting
Kids these days and their crazy hair genes. Well back in my day we had night vision, which helped us walk to school up hill both ways in the snow at night. Those were the days.
Love your videos on this channel or on TestTube, even DNews ( but your barley even there ;( ) But almost 7 Billion people? There around 7,300,000,000 humans alive I think.
Test tube is a fucking troll propaganda chanell
I can just enjoy this guy talking about anything!!
"we're almost at 7 [billion people] now"
Really, Trace? Is there a policy of trying to include at least one glaring error in each video?
klondike444 Nobody is infallible. And I for one, think that Trace is doing great working with notes alone, as opposed to the prompter he's used to on DNews or TestTube. I'm sure he; or one of the editors, can annotate corrections.
klondike444 He meant almost 7 billion counting backwards smartass. ^_^
Damian Reloaded Is that an attempt at humor?
What happened to the latest Mars video? It got taken down, but what is the reason?
50 years!?? That's laughable! We'll look the same even after 500 years!
+Sun Beam Who knows, technology will play a big role. And that didn't lift off the ground till about 100yrs ago. And didn't start really booming till the start of the new century which was only like 15yrs ago. I definitely do not agree with looking different in 50yrs. But 500 is definitely possible.
why is it that I don't like these videos but I still watch them? I think because it evokes conversation.
In 100 years people will see this and laugh haha
I love this channel! Trace is very well spoken and easy to listen to and understand.
a lot of humans will die if we migrate to space.. but maybe we should for a little while, just to thin us out so we dont continue to multiply exponentially and destroy the earth
Best channel in youtube! Great job guys!!!
50 years from now humans will be, half man, half bear and half pig.

Juan Manuel Peña Fermé Agreed please make this into a podcast
Juan Manuel Peña Fermé working on it! I think it finally went up today!! :D check itunes!
Thank you Trace! :) Going to ITunes now
im going to be 65 then can be immortal
In 50 years I'll be 68 so hopefully I'll be alive to see this.
Im going to disagree. Us humans havent evolved for such a long time because we dont need to any more. Because we stopped adapting to the environment, and started to make the environment adapt to us. We built houses, heating, farms, all this to fit our needs and make it as comfortable and as easy as possible. The same will happen when we decide to live under the ocean or in space. before doing that we will create artificial replacements for thing we need to survive, like gravity or a sun. Our space crafts will be suited to have us live in it comfortably. There for we wont evolve because there will be no advantage for any one who is born different, since environment we made is designed to suit the average human.
But genetic mutations just don't stop happening, maybe a mutation is beneficial in a small way and we adapt, Evolution!
raphael normie wrong on the first point, evolution through natural selection is an on going process, it doesn't stop we have & are still evolving, genetic modification aka "designer babies" is the next big thing I think, I mean look at plastic surgery industry & the lengths people will go to just to change themselves physically now combine that with the current/future knowledge of genetics & our growing dependences on technology.
I didn't mean that mutations would stop happening. Rather that any new mutations in humans aren't going to have any mager advantage if not any over any one else because of the fact that we changed the environment to suit the average human.
Its more about common sense. Think about it. How does evolution work? It happens when there is a mutation, and that what makes it different gives it a better advantage of surviving over the others. And when it mates, its new geens will exsist in its children. And it continues on and on and on. You end up having an off spring that can survive better. Now look at humans, then look at human homes, cities, tools, ect... (and medicine and safty in our territory allows us to live longer with less danger). its all designed by humans to suit humans. So if you have a mutation of a human that could run faster, or would be stronger, or smarter. He isnt going to have a advantage of survival over every one else. Because in a human environment, every one is safe. There is no competition in survival.
can you give other examples to how humans could still evolve in this age?
I like how these guy presents himself because he just tells you like it is not like he is trying to force his opinion on you and his views like most ppl do on youtube channels that cover stuff like this.
Almost 7 million people? Hell no.
Factology It is 7.125bn not 'almost', but 'over'
It is nearly 8 billion FFS.
Homo Spaceian!
Interesting, I forget to include popular trends and cultural fad changes in thinking about the future.
Its worth noting that throughout history, the amount of time b/w paradime shift has gotten shorter and shorter. It use to be 1000s then 100s of years before humans made leaps...now its decades.
Trace, Ive really gotten into Test Tube News recently. I like the concise and informative information. However, regarding Test Tube Plus, it may be nice to see video inserts and switching between shots of you sitting at the table to documentary style footage. Just a thought. Keep up the good work.
Is there a link to the artist's drawing? I really wish you showed the picture
This is a great channel!!! Very unbiased and always noted and separated of the facts, opinions, and theorys!!
Wherever we are, whether it be land, sea or space, I just want to hang out with the one and only Trace. ;)
i love how long but short this video is, it would help if you could show us some pictures or visualizations of some things you mention to help my imagination :)
Yes, you can feed more people on a vegetarian diet, because vegetables are more plentiful and easily produced than livestock. However, it was our consumption of cooked meats that gave our brains the initial kick to begin evolving to its modern day level. With a diet of grains, fruits and vegetables, along with a balance of lean meats if you so choose, whether it be fish, poultry, or even lean beef, we could pretty much feed the world.
Try to play some slow electronic sounds during topics like this, just under the profile. It makes the teaching more captivating. Thanks.
I was 21 years old 50 years ago. We humans have not changed but our standard of living is much, much better now. Technology has made life very easy for us in comparison to what it was 50 years ago. TV, air conditioning, sneakers, permanent press fabrics, washer & dryers and other appliances. Cheap and very abundant food.
Now, because of computers and the Internet we have access to information to a degree never before seen by the human race.
Even with all the problems that our world faces we still live in the best of all times.
Isn't funny listening to people who lack the life experience, or patience to crack open a history channel talk about how "horrible" things are now!
Between many countries experiencing more peace than ever before, the technological developments and access to information are unparalleled!
I'm one of the few who's anticipating the future with a modicum of optimism.
In every episode, I always love your T-shirts XD
I am a long distance walker, we already have night vision, people depend on seeing with eyes clearly, I use my built in night vision a lot
In the vein of evolution just a quick question: how does the initial evolution begin. Random genetic mutations? So for an example snakes prior to developing venom in their evolutionary history to the present? What factors presented themselves that forced that change to develop a venom sac gland? Were there just trillions of mutations and the species that developed the gland survived and the rest died off?
Hey look its Trace! I only just found this channel, didn't know it was your channel.
Love your videos +TestTube Plus , but it would be more entertaining to have visuals (pictures and animations) on screen when you reference things
Keep the videos coming, great stuff.
Its great work, but could you please state those stats on screen, be more graphic, over using your hands to explain and create everything ! :)
Love the questions being asked here :)
we need to talk about surviving each other from war and our own pollution first, before we can start talking about the future.
I really love this show as it is, but I wonder what it would be like in a podcast format. I feel like the show as a whole might flow a little easier if Trace had someone to talk with about these topics, maybe someone who resembles the viewer in that they are learning the information for the first time from Trace. Either way I'll keep watching though :)
why is this guy not more popular?
Like the program but either set up a prompter or do a pod cast. You're on a televised program so can see you looking at us not down.
What if the idea of aliens (with small bodies, large heads and big eyes), are actually a future representation of what we are to become? Could we look so 'alien' to ourselves?
i worked night shifts without seeing the sun for 6 months, now everytime i go in the sun it burns even just going to the car
I do not think we will need to adapt.
We will simply adapt our surroundings.
And we will implement technology into ourselves.
2000 baby here.
Unless something happens to me, I will live to see it all.
I just want my descendants to have eyes that can look at monitors for 16 hours straight without getting strained.
People often forget to take into account all the other stuff that is also supposed to be living on the Earth when discussing over-population.
This is just something I've thought of for the past few years, because natural selection affects humans far less than it used to (Im primarily referring to those living in first world countries) human evolution will be fairly different to that of other animals. The strong, attractive, intelligent will breed with the strong, attractive, and intelligent, while the ugly, weak, and unintelligent will breed with the ugly, weak, and unintelligent, while in normal circumstances the weaker animals would die out, in the case of humans they live on and pass their genes on. This will result in two different types of humans, as thousands of years from now, the gap between the intelligent and the unintelligent, the strong and the weak, and the attractive and the unattractive will grow to much higher levels, creating what would seem like almost different species eventually.
When I grow up I want to be like Trace
I don't want to criticize too harshly but... It started off with "50 years from now" and then kinda jumped to warp-factor 5 into the future.
My thoughts are - "If you want to get to the stars, leave the meat behind". Think of evolving into a non-corporeal consciousness. You'll go a lot farther and much much faster.
Robots don't prove evolution, they prove that in order for a super sophisticated thing to exist an engineer must work hard on it.
Based on our evolutionary history, I don't think 50 years from now is far enough into the future to ask how different we will look...
It seems far, far more likely that we will merge with our technology (a.k.a., H+) as a form of adaptation rather than suffer the long, hard evolutionary process through genetic selection. Advanced in computing, power systems, prosthetics, etc., all are leading is in this direction.
how i imagine humans in the near future : mixed race , light skin (spending so much time indoors) , tall , thin , smarter ....
I think that in some ways modern medicine and medical breakthroughs are kind of interfering with natural selection and evolution because those who are not necessarily "the fittest" can still survive and reproduce.
Thank you Trace!
self-transformation is are ultimate next step .
The end result is when we resemble small universes contents
"if the black holes don't suck us up first" which might tell us where we came from lol .
Just an Evolutionary Biology Master dropping by to nitpick: Some of the stuff here is overly simplified. First of all, human populations are too large and intermingled nowadays to allow new mutations to manifest in the majority population purely because they're more successful. It's called the founder effect, and since we inferior beings are here first, we will likely out-compete even clearly superior mutations due to population processes. Evolution doesn't mean that droves of inferior humans will DIE from selection. We're only just beginning to understand gene processes, but all organisms have genes that toggle on or off due to environmental factors, and this may bring rise to subsequent, more beneficial mutations. A population may evolve, while keeping the majority of its individuals contributing to its gene pool - they don't have to mostly die off; that's way too oversimplified sensationalism.
What will people look like in the future? Depending on the environmental factors, we may become shorter due to a tolerance for growth hormones in meat, and to prevent back problems. We will definitely be more intermingled, making more people share a mixed heritage. And despite the stark difference in appearance over a short time, surprisingly few of the changes will have been brought about by actual mutations.
The trouble with modern evolution is that mankind's technical expertise has trumped natural selection.
For example, there's a study that shows human eye sight is actually getting *_worse_*, because we developed glasses/contact lenses to correct bad vision. So you go through life with your bad vision corrected artificially, but naturally, you still have bad vision. This bad vision is passed on to your offspring, who in turn, have bad, if not worse vision that's also compensated for with corrective lenses. They then pass their worse vision onto the next generation, etc. So if anything, mankind's vision will become non-existent before it adapts to the darkness of space.
Other changes might be our feet - the soles of our feet may get weaker and weaker overtime since we protect them now from the elements with shoes.
We keep other problems like high blood sugar, diabetes, kidney stones, epilepsy, etc all in check with medications. These ailments aren't CURED or REMOVED, they're just "controlled" to such a degree that their affect on our daily lives is minimal. Thus, these ailments too, will be passed on to generation to generation, and will worsen each time, unless a generation can develop a permanent solution that means they won't pass the ailment on to their offspring.
In summary, mankind's ingenuity (which ironically, developed via evolution) has now backfired on us, because we're at a point of no return where each generation is more and more dependent on our ingenuity to control ailments/defects than the last (rather than letting evolution run it's course and weed the ailments out of the species), because each generation is plagued with more than the last.
Eventually, we will reach a point where every aspect of our existence has become compromised, and must be "corrected" by one form or another.
Don't want to sound tin-hatted, but sounds like we're on the fast track to something comparable to the Borg or the Cybermen, with our bodies chiefly mechanical and only basic biological components like brains remaining.
You realize it takes generations to even see a slight evolution within a species right?
Please avoid the laptop and look at the camera. It gives a nice personal touch as if you are talking to me directly.
Not trying to be disrespectful, but a serious question: Who are test-tube and Trace, and why should we listen to them? Just curious what the sources are, because they say a lot of stuff, and while it's very cool and interesting, some sources of information would be nice. Where do they get their information, and what are their credentials?
