Be sure to check out our new series Becoming Human on Nebula! nebula.tv/becominghuman
If you've ever wondered why humans are basically the weirdest animals on earth, this series will take you step by step explaining why.
Your narration voice sucks!
Very interesting!! One problem I have with this presentation, is that there’s a strange noise in the background. It is very difficult for me to hear her words (I have CC on too) due to that added noise (it is low, yet very distracting - - for people like me, that have hearing issues). I have my headphones on at the highest setting, didn’t resolve this problem.
6:03 what's the music in the background ? Its very unique.
Your commentary is very easy to understand
I am not lazy. I am an evolultionary step towards regaining hybernation capability
Just make sure to pass your genes, okay?
@@NoHandleToSpeakOf 🤣
I was thinking same 😂😂
@@mal2ksc 😄Good one!

Back in the 90’s there was a child that fell through the ice on a pond. Several hours passed before the rescue team found him. They were able to resuscitate him without any brain damage. The doctors said the reason was that he drowned in freezing water and it caused rapid drop in body temperature. His body didn’t have time to build up any of the dangerous chemicals. He was resuscitated while still hypothermic preventing any degradation before his body began to function again.
I’m not saying I want to try it myself but that sounds like a good place to start studying how to make people hibernate.
the thing is it is tough to replicate that without risking killing the test subject.
We're still years away from human experimentation, regarding hibernation, but there are a handful of reported cases of possible human hibernation
@@sirBrouwer either Russia or China will probably be the first to test anything. Political prisoners seem to be preferred test subjects.
@@trixrabbit8792 or USA with its nazi scientist working for government after 1947
@@LudovicoTaddei we really need more human test subjects tbf
The closest I ever came to hibernation is when I caught a cold, called in sick, and slept as much as I felt like, only getting up to eat and go to the bathroom. I was asleep for 22 out of the first 24 hours, and the next day I felt so much better, feeling like it accelerated recovery by days. The difficulty is having to fight the compulsion to be awake and wanting to go about life.
One time i felt sick so i slept in till ten the next day after work, i usually wake up at 7 naturally and my mom was getting worried because she picks me up at ten on my days off, she thought i had fallen down my basement steps before i could make it out the basement door.
@@Imbatmn57 ok?
Yeap, same here. I now have a rule that I just sleep when I get sick. I always recover so much faster then even if I just sat around watching TV. There is a REASON why we're so tired when we're sick.
It's the body flat out going, "YO YO YO! GO TO SLEEP! Stop moving, stop burning energy by focusing on stuff, like TV etc, stop thinking even, let me repair myself!!!!"
Honestly it's to the point now where I just naturally can't read a book or watch TV when I'm sick for the first day or two. My brain just shuts down and won't let me. ... and if I force it to stay awake, let me tell you; the cold just gets worse and I'm out of it for days longer then otherwise.
@@OgdenM thoughtytwo
@@OgdenMthe hard part is the actual sleeping for me. I can be physically suck, but my brain keeps me awake. I’ll try to take a nap in the afternoons but after being in bed for 3 hours, I usually get maybe 15-30 mins of sleep. I’m somewhat jealous of those who are good at sleeping.
I believe I once read that ectotherms (amphibians and reptiles) devote a large portion of their genome to multiple chemical pathways that allow them to function at different temperatures. One advantage of endothermy (birds and mammals) is that it simplifies the chemistry needed to run the body at the expense of needing more calories. One advantage of this is that it frees up space for the genome to evolve other useful traits (big brains). Not sure what this hypothesis is called or if it’s still considered plausible. It’s an interesting idea, though.
interesting point, but isnt like +90% of our genome just trash from the past
if someone has a further combined explanation for my, and Noah's points, please tag me
@@darthtrump4428 I learned that only 1,5 percent if our Genom codes for genes, but that doesn't make the rest useless.
Some of the rest is necessary for regulating our genes, so proteins only get made when they are needed.
Other parts of our genom are leftovers from virus infections and called transposons (I'm not a native English speaker so the name transposon might be wrong), these transposons are mobile (also called jumping genes somtimes) and can..well jump.
While jumping they make it possible that genes get recombined.
Also at the ends of our chromosomes we have non coding ends called Telomers wich protect the ends and mark the end of the chromosomes.
These are the few things I can come up with reasons why not 90 percent of our genome are junk, hope it helps.
Have a nice day/evening/night.
@@darthtrump4428 I study biology at a german university and had a module of genetics this semester. I was provided with the following numbers:
Genes account for 20-30% of our genome.
Only 2-3% oft these are actually coding for rna and proteins, the rest of these 20-30% are regulatory sequences, introns and pseudogenes. 70-80% of the dna on our genome are not genes. These 70-80% are tandem repeats (10-15%(you use those for genetic fingerprints)), scattered repetive(25-40%(ofen transposomes)) or single copy/low copy sequences(the rest of the 70-80%).
That leaves a lot of space on our genome. A possible reason for this empty space could be to prevent mutations from damaging our coding genes whilst profiting from mutations on non coding genes.
Another theory is that repeating sequences might play a role in the folding process of chromosomes.
Those are just theories, they are not proven yet.
Sorry for possible translation errors, all the material i have is sadly in german. Hope i provided some interesting information.
Thank you for that interesting information!
Not a biology person, but is it possible that the remaining stuff in dna which looks empty is kind of like software? What I mean is that it may be used for storing "how to" like in case of sea turtles how do they know to follow light and sort of stuff. Idk just a thought
Ive heard the stories of people falling into frozen lakes being revived after 40+ minutes, but never have I heard of the hiker who survived 24 days of exposure. That's wildly interesting.

In my most recent semester of school, I had to do a project analyzing the quality of a science news source. I did my project on Real Science. I got 100% on that assignment. Thanks!
Awesome :)
How do you analyze the quality of a news source?
@@firdaushbhadha2597 I should probably say 'science reporting' source. The assignments were to look at sources that were not primary sources, such as research papers for peer-reviewed journals, and then research beyond the reporting sources to see how accurate they were. For example, if the source cites additional primary sources, such as research papers for peer-reviewed journals, if the source has advertising, and if so, how the advertising does or does not influence the information being conveyed, if there is any indication of secondary agendas, et cetera. In the assignment in which I wrote about Real Science, I wrote about why it is a reliable source of information. In another one of these assignments, I also wrote about why Infowars is not a reliable source of information.
@@jeremiasrobinson amazing thank you! I always like learning how to improve my due diligence, especially in this age.
@@firdaushbhadha2597 Both real science and real engineering will always have a extended list of references below the video.
if other science / news based videos have them. that will make the video credible as you can look at those resources and use ways to cross reference those sources to go even deeper.
like with this video alone they have given 14 referral links they have used all from credible sources .

Great video, hibernation is such an intersting phenomenon and you narrated it pretty well.
The only fallacy of your narration is to group togheter ectotherms' and endotherms' (torpor) hibernation. This is important because the hibernation process of ectotherms is passive, forced by environmental conditions (and which also requires massive adaptations like butt breathing), while torpor is an actively regulated phenomenon (although we still don't know the exact mechanisms). To put it in a simplier way, an animal can arouse from torpor even if the enviromental conditions stay advers, while an hibernating ectotherm can only be aroused if the envrionmental conditions improve (substantially if the wether gets hotter).
Anyway, that's not something I wanna argue about, it's just that you did such a good job and viewers seem to be really intersted in the topic, so I wanted to add at least a bit of my knowledge.
Dwarf lemurs fascinating. By the way, I have difficulty communicating because I had a stroke in Broca’s area, the part of the brain that controls speech. 2/8/2021 but I lived again. (My wife helped me compose this.)
God bless you and your wife ❤️
I had a stroke that gave me some aphasia, but I could generally speak well enough to be understood. Over time, I improved, and now people can hear no impairment to my speaking at all. Hang in there; even if slowly, things do get better! My typing went from about 5wpm up to 60 or so. Still not the 75-80 from before the stroke, but getting there.
Wow this is phenomenal content. Thank you
The TH-cam video was truly captivating! The content was insightful, and the presentation was engaging. I appreciate the effort put into creating such valuable and enjoyable content. Well done!
The originator of this channel exerted a tremendous amount of effort to gather data and presented it in a superb manner. The concepts that I grasped about Hibernation in this video are exceedingly captivating and enthralling, particularly the details about Mammals and Reptiles. Moreover, the creator's use of cinematography to showcase the Soft board Pin pictures in a group of hibernating animals and pointed to one specific image at the timestamp 2:46 is remarkable. I am fond of your channel, and to support you, I watched the full advertisements shown in your videos without skipping. Your content is admirable, please continue producing more.
This episode was absolutely mind blowing!
You do such a good job of these videos. Well done!
I like how you present the information! It's very interesting and next level. Maybe you could add some sci fi touch to the video/editing tho.

Thank you and everyone involved.
What a beautiful and informative video. Thank you so much
What I love about this channel is that it answers questions that I have always wondered about but never actually bothered to look up. "Where did hibernation even come from in their evolution history." Literally have wondered this myself, I love this channel.
As someone that could be an Olympic gold medalist in sleeping, yes
teach me!
And Olympic gold medalist at snoring as well.
Snoring and deep sleepers go hand in hand
@@HumanBeingSpawn Snoring usually is a sign of disturbed deep sleep due to suboptimal oxygen supply. So your body starts gasping for air due to lower oxygen causing snoring. People who don't snore usually have deeper and more efficient sleep. Chronic loud snoring is a sign of sleep apnea which significantly decreases lifespan of those who suffer from it and don't even notice because they think they are just snoring. Always snoring is a very bad sign if you aspire to live a long and healthy life. Deep sleep and snoring are contrary to each other.
This may be entirely wrong, but it seems like the simplest explanation for not losing muscle/bone mass is that for non hibernating species losing those things is an adaptation. As in, we evolved to LOSE those things to conserve energy and recoup resources when they're under utilized. So the way hibernating species don't is by not doing that 😭. Like the loss of muscle and bone mass is an active process that doesn't occur in animals for whom it would disadvantage.
wow! I love this channel and the narrator :D cool stuff!
Excellent video as always!
really excited about your new series, I absolutely LOVE Nebula (and CS)! Especially now with TH-cam hiding dislikes, it's become almost impossible to tell if the content you're watching is any good until you've already wasted a bunch of time finishing it. With Nebula I know that everything on there is top quality stuff made by brilliant, passionate creators (like Real Science!) so I don't even need a like/dislike counter. TH-cam, I'm sad to say, is now mostly filled with clickbaity, poorly plagiarised junk dressed up with a bit of fancy video editing.
Nailed it dude. With an AI voice over
The only creatures to walk on two legs? Surely you mean the only mammals to do so (interestingly enough, kangaroos don't really walk with two legs, they hop, when they do 'walk' they use all 4 limbs and even their tails, leading to a unique pentapedal locomotion), the ratites have us soundly beat in terms of species with bipedalism :P
Great video, this is definitely one of my favourite channels right now!
yeah you are right! I should have clarified
Considering pangolins, I'd say, humans are the only mammal to regularly walk upright on two legs. I think that should be enough extra conditions to be true.
Ratites don't have us beat in bipedalism. Humans have the highest endurance in the animal kingdom and it's due to how efficient our form bipedal locomotion is. Both our arms and our upper body act as counter pendulums when we walk or run. Essentially, we use far less energy compared to a digitigrade biped.
@@redwolf4611 yea I meant in terms of there's only one species of us and many species of ratite
@@xiphosura413Fair, but there’s probably 1,000 individual humans for every individual ratite. That’s not to say we should go to war with them or anything. We all know what happened to Australia
I love snuggling up at home during winter but I love it so much that I would never want to hibernate. Like I always say " you'll never feel air as fresh as you do when it's ice cold out" the most amazing feeling ever nothing but pure air.
I think we make a false assumption that bears (and other animals) are not aware of their surroundings while hibernating. Some might not be.. but bears I seem to remember that they 100% are. They will wake up if distributed enough. Otherwise their brains are just like, "NA, stay asleep, we're safe."
Absolutely love all your videos
I feel like a challenge was set for how many times one can put “butt breathing” in a script. ^^
You're challenging me to butt breathing?
I had been waiting for this science for long. Great thanks to @RealScience for such amazing content.👍👍👍
Excellent channel, excellent video.
On the supercooling of squirrel blood - blood is full of a crazy amount of proteins, salts, cells, and other compounds. How could it be that the water in this blood is super cooled due to its purity?
Thanks, and always look forward to your videos.
That's what I was wondering, surely cells and proteins and such naturally act as nucleation sites? I know from personal experience one can supercool carbonated water, which also seems too unstable, but blood is another whole order of magnitude messier than even that.
If you lower water content and saturate the water with salts et cetera, then it won't be able to freeze (more or less), I'm thinking that is a closer explanation.
@@kindlin , I agree. This seems more likely due to one of the so-called colligative properties:
en.wikipedia.org/wiki/Colligative_properties
"Depressed freezing point"
EVOLUTION designed this?? A basic summary of what that means...
In the beginning was nothing but then it somehow became as big as the universe. Then there was dirt and water but then somehow it became alive. Then there was an organism but somehow it had the structure and information to reproduce. Then one decided to be a male and somehow another organism became female and somehow at the same time, with fully functioning structure and information, they reproduced. Then they grew branches, then arms, then fins, then legs, then wings, and breathed water and then air and now we see them all perfectly mutated to flourish in their ecosystems!
Seriously, Have you considered how a butterfly came to be? What came first, the egg? caterpillar? chrysalis? butterfly? What mutation could cause a crawling creature to suddenly hang upside down, dissolve its organs and appendages and 2 weeks later emerge as a flying creature? And then find another butterfly to reproduce? Truly a fairy tale!
How did the grub get these incredible organs? Mutations don't give new information, they corrupt existing information.
It is glaringly obvious we are part of creation. The world around us is so incredibly complex that design is the obvious, logical and scientific conclusion. Jesus was a real historical figure who claimed to be God. He also confirmed that he created the world and was coming back a second time to reward and judge the world. He proved this by rising from the dead and fulfilling many prophecies. He also foretold what would happen before he would come again. These things have been coming to pass more and more. He loves his creation and has a purpose for everyone of us! But the evil we see in the world is not from God. We have a cruel enemy and you can see the devil's handiwork more and more. Please look into this urgently and with honesty. God is not a policeman in the sky, nor is he a genie that grants wishes, he is a loving Father who is caring and merciful and rewards those who seek him. Do not decide who God is by looking at religious people, you must decide who God is by reading what he says about himself in the bible. Then you would have judged fairly. Start with John or Luke. These are eyewitness accounts of what Jesus said and did. There are many resources to answer your many questions. Especially on creation and evolution see creationdotcom.
Seek the LORD while he may be found, call upon him while he is near (Isaiah 55)
For since the creation of the world, God’s invisible qualities-his eternal power and divine nature-have been clearly seen, being understood from what has been made, so that people are without excuse. (Romans 1:20)
To realise that your life is precious, you are loved, and you have a purpose, is real freedom and responsibility. There is an epic heavenly battle for your soul! You're never alone, reach out from wherever you are, Jesus is there, trust Him.

Very interesting video! You were correct in mentioning that Bears are not true hibernators. You neglected to point out the all true hibernators undergo bouts of arousal and must have access to water. I am also surprised that you did not mention the tissue "brown fat" that all true hibernators possess which provides the energy needed for arousal. Finally, Bats happen to be the best hibernators on the planet. I always enjoy watching your videos! Thanks!
But don't we humans also have brown fat, albeit very little?
@@hannahwinterhalder741 we do, and we can increase it thru a process called "adipose tissue browning", but most of the west doesn't eat in a way that can do this.

I've never encountered myself, but I've heard a lot about yogis who meditate like hibernation at very low temperatures since ancient times in Himalayan mountain caves.
Very interesting. Prior to this video, I knew next to nothing about this topic. Thank you.
We tend to want to sleep more in the winter, have shorter tempers, and prefer fewer survival-based stressors (such as being short on food, late bills, etc), yes? That may be as close to a current form of hibernation we as humans have.
Recent events in my personal life have prevented me from hiding away in my home with as few extra people as possible this past winter (including sleeping longer, slowing my life down in general, etc like I do every winter), and while shit's calmer now about halfway through spring, I've felt the difference to a startling degree. I have less energy, have gained more weight, less patience, less give-a-damn, my sleep patterns are all sorts of screwed up, I need to put more conscious effort into maintaining my mental and emotional health, I have more aches and pains, and I won't touch on the no-longer-like-clockwork monthly cycle.
To be clear, these changes may feel huge to me, but no one else around me has noticed these issues and my doctors have no answers. I'm going to go out of my way to not have a busy, non-private winter when it rolls around again. ~6 more months to go...
Sorry about the massive personal dump, but a kind of "intentional hibernation" is what best describes what I usually do during the winter, and having been forced to skip the last one, I'm starting to wonder if it's not just a me thing.
I wonder if we human-animals haven't figured out how to purposefully hibernate, as our brains are so big we've forgotten how to do it instinctually?
Please don't mind this 5:00AM sleep-deprived text wall. Speaking of hibernation, I'm going to go to bed lol.
@@by-the-by. And it can happen again at age 39. Previous doings of various kinds of growing up don't make the next one to roll around any easier lol.

Ive been in hibernation for years. its definitely possible.
Thank you for this video.
I once saw a film about some astronauts traveling thru space in state of hibernation. Well, it didn't end well for them...
Me commenting in year 2125: This video aged well.
My wife thinks that I do hibernate. I’m disabled and in the winter sleep as much as I can, up to 18 hours a day
I just read a report that humans might need much more sleep in the winter!
Yep. My sleep record is 70 hours, went up to pee twice. Had incredible dreams, I still remember them.
(I live way up in Northern Sweden. And yes, I have my family as witnesses.)
Yes I can sleep all day every day. I lived a tough life, I enjoy the sunset years 🥰
winter depression kind of feels like hibernation, and as I understand it many hibernating species still get up from time to time for basic routines like hydrating or relieving, so honestly I wonder if some people with SAD might just have remnants of the hibernating spirit within them
Being able to have a form of hibernation or as in science fiction It's referred to as suspended animation would allow for space travel and have a practical function of placing an injured or diseased body in stasis until they could be repaired or cured 1:04 😮
I used to hibernate when I was broke asf it works
Well sleeping at nights is a kind of hibernation too. We spend our passive time at dark nights by slowing down our heartbeat and breath in sleep. People who sleep less dies earlier. So sleeping is kind of leaving activity to day time and hibernate at nights. Also 8 hours in conscious takes much time than sleeping 8 hours. Sleeping is like time travel to future.
No. Wrong.
Sleeping is time travel to breakfast
The point is that the physiological changes that take place between sleeping and hibernation, while outwardly similar, are actually quite different and have substantial affects. As pointed out in the vid (and this was new to me) some animals can have _sleep deprivation_ while hibernating, as their brains cannot properly do what they need to do, as they aren't sleeping, they're hibernating.
@12:05 Hey! Alan! Makes an appearance 😂
During the winter months I walk outside without shoes when shoveling snow. I love the cold weather

The scripting and narration of this video is nearly perfect. Is the narrator a real person ?
Is my rent going to be lower during the months that I hibernate?
imagine calling your friend and being told to leave the message due to hibernation.
or your spouse mad at you and went hibernation for two months 😁
Heard about farm workers in medieval France who did a form of hibernation to survive the harsh winters. Not the same as animals which have evolved to hibernate but it involved sleeping or slumbering for extended periods, eating very little and minimal activity. They had not the fuel or provisions to survive the winter any other way.
Makes sense. All humans actually used to sleep A LOT more then we do now. Electricity changed us drastically because of artificial light. Before that, it was common for people to basically go to bed within 2 hours after sundown. Wake up for an hour or two in the middle of the night and then sleep again till dawn.
Which for say someone in the PNW could mean up to 12 hours of sleep during the winter! Potentially even more when you factor in the lack of light because of the clouds.
The whole old timey thing of people using candles, gas and oil lamps etc to light up their dwellings at night was mostly for the rich. That stuff was expensive and most people didn't have money to provide light for their dwellings for more then a few hours a day.
Good point. My neighbour had a power failure in the middle of a cold winter. Her whole place is electric. When I asked what did you do she replied I went to bed early and remained there till power was restored the following day. @@OgdenM

Perhaps it is far fetched, but i think part of the slowing down metabolism is surely still in our genes and has helped us survive as humans before during changes of temperature and food resources. And i think you can see that in certain individuals where their metabolism gets super slow to adapt to things we put our bodies through now. Like surely not the slowing down we know from hybernation, but things like diving where we use way less oxygen and slow our heartbeats, or being more efficient during exercise, or how starvation especially in people with anorexia change the metabolism. Also how our mitochondria adapt even before we re born to adapt to the conditions the pregnant person is exposed to. I think those all play into the spectrum of energy conservation; which i believe isnt studied enough yet but im curious to see about more things we learn in the future about those aspects
EVOLUTION designed this?? A basic summary of what that means...
In the beginning was nothing but then it somehow became as big as the universe. Then there was dirt and water but then somehow it became alive. Then there was an organism but somehow it had the structure and information to reproduce. Then one decided to be a male and somehow another organism became female and somehow at the same time, with fully functioning structure and information, they reproduced. Then they grew branches, then arms, then fins, then legs, then wings, and breathed water and then air and now we see them all perfectly mutated to flourish in their ecosystems!
Seriously, Have you considered how a butterfly came to be? What came first, the egg? caterpillar? chrysalis? butterfly? What mutation could cause a crawling creature to suddenly hang upside down, dissolve its organs and appendages and 2 weeks later emerge as a flying creature? And then find another butterfly to reproduce? Truly a fairy tale!
How did the grub get these incredible organs? Mutations don't give new information, they corrupt existing information.
It is glaringly obvious we are part of creation. The world around us is so incredibly complex that design is the obvious, logical and scientific conclusion. Jesus was a real historical figure who claimed to be God. He also confirmed that he created the world and was coming back a second time to reward and judge the world. He proved this by rising from the dead and fulfilling many prophecies. He also foretold what would happen before he would come again. These things have been coming to pass more and more. He loves his creation and has a purpose for everyone of us! But the evil we see in the world is not from God. We have a cruel enemy and you can see the devil's handiwork more and more. Please look into this urgently and with honesty. God is not a policeman in the sky, nor is he a genie that grants wishes, he is a loving Father who is caring and merciful and rewards those who seek him. Do not decide who God is by looking at religious people, you must decide who God is by reading what he says about himself in the bible. Then you would have judged fairly. Start with John or Luke. These are eyewitness accounts of what Jesus said and did. There are many resources to answer your many questions. Especially on creation and evolution see creationdotcom.
Seek the LORD while he may be found, call upon him while he is near (Isaiah 55)
For since the creation of the world, God’s invisible qualities-his eternal power and divine nature-have been clearly seen, being understood from what has been made, so that people are without excuse. (Romans 1:20)
To realise that your life is precious, you are loved, and you have a purpose, is real freedom and responsibility. There is an epic heavenly battle for your soul! You're never alone, reach out from wherever you are, Jesus is there, trust Him.
The only creature to walk on two legs?
Ostrich. Emu, penguin, to name a few.
Not only water-turtles but also terrestrials one's, and also some insects, and even hummingbirds (just torpor)!
I think it would require getting back in touch with the enteric nervous system, the first brain. I think it's primarily in control of hibernation.
15:14 Ostrich: Am I a joke to you?
(... and pretty much all other birds.)
At 7:50, the chemical formulas appear to say that anaerobic metabolism gives twice the ATP. I believe aerobic gives ~30 ATP per glucose.
Hibernation techniques can be explored using meditation, specially called YOG, there are yogis and sidhas in Himalayas who are living for hundreds and thousands of years using this technique, during YOG the breathing rate falls and sometimes to such low levels that you can't even feel your breath..
There's a story of a couple and their baby caught in a snowstorm that lasted for days. They abandoned their car and retreated to a cave. I think the husband either passed away or went for help and the mother was hypothermic beyond and passed away but the baby was discovered to be frozen but had a extremely low heart beat and was successfully brought back with no effects from the experience.
4:10 dude was just feeling the music
5:35 seeing how it's convergently developed in multiple different, unrelated clades I highly doubt this hypothesis. Rather, I think it has moreso to do with the epigenetic markers that fine tune our base metabolism; that would make more sense as to why animals respond to environmental cues rather than purely genetic determinism to induce estivation or hibernation.

Please do a video on swordfish! 🙏
On a planet with ice ages and Milankovitch cycles it seems we’d all benefit.
10 days in Texas last year would have helped me…
A few things I would argue: I have seen Artic Hares running on their hind feet, i.e., bipedal motion, like humans. I have seen primates throw things (usually clumps of sod) while angry, and elephants will throw dung with their trunks when irritated. I know that as I was the target once, but she missed! Otherwise interesting. I live in the far north which has winter days, and nights, and if I am not hibernating in winter, I at least slow down, as do many others up here. It is the opposite in summer. Not quite a hibernation cycle, but heading that way.
I think, for the reason you specified, bipedalism is understood to be when it's the _primary_ means of locomotion.
My brother can also attest to the throwing ability of elephants, as one once threw a stick at him - and didn't miss. He's had a profound dislike of elephants ever since 😂
However, what's referred to here with regards to throwing capability is that humans have evolved to have especially well-articulated shoulder joints that allows us to do the characteristic throw of something like a spear, and very effectively at that. No other animal can do that. (See Real Science's video on human biology.)
@@mnxs My dad had a story about elephants throwing rocks large enough to potentially be lethal at people. They were just laughing about it until the elephant ran out of rocks and switched to poops. I guess people are more scared of getting messy than getting killed LOL.
thank you

Behold, the only creature to walk with two legs (besides kangaroos): man!
I present to you a man that quacks!
I cannot always control what goes on outside. But I can always control what goes on inside.
So fun fact for the day: its recently been suggested that Neanderthals may have engaged in hibernation, as researchers found lesions on Neanderthal bones that match up with lesions created on the bones of animals such as bears. I’m waiting to see follow up papers to it as it’s understandably controversial but it could give “hope” that under the right environmental pressures, our species could evolve the ability to hibernate
