- This is a report of a software project that created the conditions for evolution in an attempt to learn something about how evolution works in nature. This is for the programmer looking for ideas for interdisciplinary programming projects, or for anyone interested in how evolution and natural selection work.

He lost me at being the first person to ever claim breeders are evolved an focusing on breeding is evolution. I don't think anything outside of this software he programmed to act this way supports this. Even breeders hate being called breeders yet according to this software it would be like being Kobe Bryant.

I like how David feels sad about these computed creatures dying or getting murdered.
Really? I found it sort of sad. Poor guy is doing a simulation that proves the value of death, yet it is lost on him.
What he should do is give the creatures compassion and hatred and then hardwire them so that hatred and, ultimately kill signals, are generated proportional to the product of the creatures compassion, the genetic similarity of any death in front of it and are directed at the assailant.
Then he might learn something.

David, I watched your video this morning after learning about The game of life. You stepped it up with the little brains and neural connections, genes and mutations. You are excellent in didactics. Please go on. Your channel is awesome.
a moment of silence to dots which cannot survive in this harsh simulation
In these simulations the places where the children were “born” were completely randomized but in reality places of birth are also “inherited” from parents! If your parents lived at the Equator you wouldn’t suddenly appear at the North Pole! I think that is a very significant detail that should be added!
I think that both perspectives must be taken into consideration. The simulations one exclude that fact and by doing this it isolate somehow the brain from the nature so in that way we can study much faster the brain development related to itself. If we also study the brain by adding the missing factor we emulate better the development in real life (where we are passing information not only by genes but also by environment) which is also very important. We can even learn more by studying both sides and compare them.
@@olarmariusalex
I agree. It all depends on the end goal: if you want to study one particular feature isolating factors might help narrowing down the amount of information that you’ll have to process but it will make the model less accurate. Adding factors will make processing harder but the model will be closer to reality.
And there’s one catch - in real life all factors could be connected and it might be that in order to get some kind of result you would need to simulate all of them because with just one of those missing we might not have the right conditions!
Note, that it's a simple simulation. But you're right.
Another issue: generations don't born at the same day, don't live same duration and don't die together. Generations overlap. Also, a gene should control the lenght of their lifes, another should define the age when they make children.
Another issue: they should use and consume energy (by eating each other). Who runs out of energy, he or she should die.
Can't stop: they should produce, waste (shit). Others should consume it, it would fill the energy, but not as much as if he or she eating other. A gene should control whether the particle can kill other ones (predator), or just eat, well, other's waste (vegan).
This model is simple about how early single cell organisms could interact and swim away from hot dangerous places. Food could passively diffuse into them can be assumed. Overlapping generations would maybe only relevant when the age sense is enabled and when age variable has some useful functionality.
Unfortunately, that wouldn't work here. The simulation is set up to see if the population can navigate to a certain area. If they generated close to their parents you would introduce a bias. For example, in the first simulation, all generations that began in the east would just keep reproducing regardless of their genome.
You could change the selection criteria, but I think the way it is now lets you see what's happening clearly.

I never ever saw a hour long video on TH-cam. But I was glued to my screen. Excellently edited, fun, inspirational and entertaining. Please make more videos. This is what I’m here for. 🙏
2:00 Evolution doesn't have to explain where the first self-replicating molecule came from. Chemistry does that just fine.
Evolution takes place in the latter part of this inevitable chain of events in certain optimal conditions:
1: Atoms form molecules. Happens quite often.
2: Molecules are sometimes formed that oscillate and move.
3: Molecules that oscillate and move sometimes happen to move in ways that construct other molecules.
4: Sometimes molecules that construct other molecules happen to construct copies of themselves.
6: Molecules that self replicate become super abundant. (evolution)
7: Random events lead to errors in the copies (evolution, mutation)
8: Molecules that happen to mutate to replicate faster or better become a the new fittest replicator.
9: As atoms and molecules to build from become scarce, replicators that steal from other replicators keep replicating and become fittest.
10: Replicators that happen to build little shields for themselves survive better and become fittest.
It's all inevitable, and doesn't really require proof other than "chemistry" as a whole.
Thanks for the explanation! Now the only deep questions remaining are located before the 1st step, one of which being "how are attoms formed?"
But I guess the more we learn about this world, the more there is to question huh?
@@firegator6853 Very true. Why does a universe arise, why does a universe behave as it does, can it behave differently, and so on. There’s no end to that.

My own world doesn't include those things either. I am aware of this youtube thing right here, obviously, and love exploring the knowledge contained herein, but it isn't a priority. I am often busy just living life, in a world far far away, powered by an infinitely small, very subtle and basically nonexistent, singularity, within the singularity. It's something I fondly call the duality, the duality actually is Within the singularity. My world is like a black hole trapped inside a black hole, event horizon within event horizon. I couldn't make this up if I tried. How deep can we go? Perhaps not objectively real like the singularity, nor as magnificent, but my world is real enough for this old Irishman, and still magnificent because it was derived from such a perfect hottie of a singularity! Wow, what a babe, that source of my world. Can you imagine the magnificence of a hottie that is powerful enough to be the source of universes? Now THAT is a total babe right THAR! Right Thar!

The reason why "kill" trait was bi-stable is because there's no selection pressure associated with it. Would be cool to add a "kill the killer" trait and see whether it leads to a larger group surviving. Or will it start wars? :)
Can we please see this program simulated?
Great insight
you could either get a mob mentality that swarm the killers, (without consequences, ie 'legal kill') OR a couple of 'sherifs' evolve that seek out the killers........
just what I was thinking, you should try to set it up to see if you can promote cooperation.
One thought:
if you have the kill gene, other individuals can see that and kill you ahead of time, you can call that the self defense gene.
Another idea:
Maybe then add Size gene to make individuals more likely to win a fight, However, being bigger will require you to collect more resources in order to survive.
You can show it graphically by altering the actual size of the dots!

I was working on my own evolution Sim game that I was getting bored with. I came here for some fresh ideas. This video delivered. The neural net stuff is next level.
There is a similar algorithm used to train neural net AIs called NEAT. Genetic algorithms that work like this (testing groups of nets, keeping the survivors, replicate and either combine or mutate) are turning out to be one of the most successful AI machine learning models.
TH-cam algorithm's selection has finally brought this video to my recommendations!
This was amazing. At no point in the video was I confused, bored, or even slightly distracted. I didn't even realize an hour had passed till you mentioned the the programs you used to make the simulator. Amazing talent and great idea, I loved every second of this.

Interestingly, I think this also explains why some creatures have smaller brains than others… in your four corners experiment you would get to the point where having a massive brain has no advantage, if all they need to do is go is get to the corners reasonably competently. Our brains consume a large amount of energy, so in some situations having a larger brain to solve certain problems starts to have a disadvantage. It would be interesting to see a simulation that allows neurons to be added, but at a cost to find more ‘food’ then ramp up the challenges.
yeah the next step of those might be a cool scenario where mutation can change the number of connections
and having "food" factor, maybe making creatures that found more food, then they consume survive and reproduce.
then having something like 1 food is worth like 10 connections.
so a creature that have like 300 connections need 30 food to survive.
A big brain is definitely evolved and maintained in a population only when life is a challenge that requires a brain. When survival is simple and intelligence is not required, a brain is an expensive luxury. There are primitive chordates called ascidians that have a brain as free-swimming larvae and lose most of it when they become stationary adults.
One way to sort of simulate the effect of a larger brain could be to add a delay of one simulation step to each internal neuron. It would enable more complex behaviors with loops but cause more complex networks to potentially move slower. It would require modifying the simulation code quite a bit though as the state of each network would have to be carried over to the next simulation step.
Add a consume action, so they can potentially cannibalize each other
@@reyariass I think that would result in the population splitting into a "herbivore" majority and a "carnivore" minority.
This man needs to rent a super computer to really do some amazing things. Lets get him there.
let him cook
agreed need a super computer for sure
Watch carefully what happens around 40 minute 🙂 increased capabilities doesn’t really affect organisms performance already, not nearly as much as going from 2 to 8 neurons. You can have whole computation power in the world, but it wont really unfold any discoveries. Regular computers are already very capable of doing very complex simulations, even what’s shown is amazing. Having more power is cool, but I guess what I want to say is that you can do a lot even with mediocre hardware, don’t think you need a supercomputer to carry those experiments.
4:00 DNA works not in single letters, but in "Codons" - that is the actual "letter" read out is comprised of a triplet of the 4 molecules. That opens up quite a lot more values per position in the datachain. That brings us to 16 values per molecule, times 4, makes 64 Codons/Values per actual read-out position. That is way denser information than hexadecimal (16 values per position). Two of these Codons (I'd have to look up the exact ones) act as "START" and "STOP" indicators for the Rhibosomes (molecule factories). Add to that that the Rhibosomes read forwards and backwards on both strands of DNA at the same time. This also allows for a lot of white noise in the DNA-"Code" to happen, which gives room for mutation (positive and negative) as well as padding-insulation against damage. Many "production-instructions" on DNA are also present multiple times for the same reason of contingency against error and damage, as well as for production quantity.
There is just one start codon: AUG, and there are actually three end/stop codons: UGA, UAA, and UAG. Also, it's spelled "ribosome"(unless you are talking about the band)
Good info though 👍
Does that not also exponentially increase the complexity and need for precise compatibility to survive and be a compatible mate with another genome (because the video states one requirement is to find a mate to reproduce)?
This is awesome. Interesting, useful and well explained, both the concept and the idea of how it was done. There should be much more of this kind.
This is genuinely one of my favorite videos on TH-cam. If I could point to one piece of media that genuinely changed my life forever, it would be this video, because it launched my interest in programming neural networks, which eventually led to me going from a freelance artist background to a data engineer.
That's amazing. I'm happy for you, friend
What's pretty interesting to me is that this exact method of programming neural net AIs is currently one of the most successful and promising machine learning models for many applications. It's a pretty perfect (and cool) example of the NEAT algorithm and a great illustration of how it works as a general method to make neural net AIs that are effective at solving all kinds of problems..

The reason the killing creatures thrived is because there's no repercussion and almost no cost for killing, it only takes up one neural connection slot. There's also the fact that the more they kill, the more they get to reproduce. It would be interesting to see what happens if there was more mechanisms related to killing, for example:
- make creatures unable to move after killing for some turns
- give creatures the ability to choose to avoid reproducing with killers
- give creatures the ability to defend themselves
Starvation, or it's equivalent.
As a Biologist myself and with only a rudimentary knowledge of coding this is very interesting and a joy to watch!

38:30 How it works is when N0 activates, N1 suppresses N0, and suppresses itself as well. This little solution here has this result: N0 triggers, triggering N1, which suppresses N0 and itself, effectively resetting the neural network.
Don't be discouraged by your level of understanding of coding. I've been a developer for 10 years and 95% of my work is very rudamentary. It will also get better as you build new things. Take python and your best ideas and run with it! I took lots of biology classes in college and there's plenty of work to do in your field!
I hope you didn't waste your time on the learn to code meme since chatgpt can do all the stuff for you now lmao

I was hoping they would use the pheromone for reproduction but also so the kill population can track them down. So the selection would be did they move to adjacent squares and were they similar enough to reproduce and the selection out of population would be did you get killed (eaten), or age > 100. run and see how long the eaters have before cannibalism and highlander (there can be only one) sets in or as it would be difficult to reproduce when you want to kill those beside you how long until the eaters die out.
A hunger number would also be good. No more resetting the population to a known quantity just let it rock.
Hi David
I may have a simple solution for the kill neuron: change the scenery :)
Most of the comments here assume that the genenpool needs (rather complex) additions to solve the problem of the kill gene. But that is not how evolution works. Evolution is blind, but is perfectly able to “control” the kill gene, probably even with as few as 2 existing genes and a few connections.
Also David reasons backwards when he wonders about his kill gene. He forgets to think about one of the 5 key features that drives evolution. Selection.
David creates selective environments, but wonders why evolution is so cruel to allow for a killer gene to kill so many, even when none of these environments selects for traits related to killing, because there is space enough for everyone to fit in the box. What does it mean?!
It means that evolution is blind.
His environments don’t select for killers, but they also don’t select for non killers. Evolution is blind. If the environment doesn’t care about killers, then evolution doesn’t care (that is.. as long as there is at least one survivor at the end of the generation to fulfill reproduction)
To solve (control) the “issue” of the killer gene, create a selective environment that selects for it.
The kill gene works by bumping into each other, right?
Create a selective environment based upon bumping into each other for reproduction.
If the kill gene is active they are not able to reproduce. 2 genes organisms in this environment would quickly select for not having a kill gene active.
To maintain a kill gene but not use it always (control urge to kill) needs more intelligence, but could be achieved with maybe 3 to 5 genes already and a lot of connections. And of course a selective environment; by using the first rule (Mating) + an area too small to fit the whole population (competition for space) should do the trick.
David thanx for the video! Hope you will continue making videos and research evolution. I’ll follow you
This is one of the most well-explained videos I've seen in TH-cam lately. You have a talent that should be shared with the world!
ie, He needs to reproduce wih some scientist or mathematician
Bro He shared his creation in TH-cam so it will reach most of viewers around the world.
You tell everything that needs to be told (tech, tools, background). This is awesome.
My friend...
This was a great video.
Please make more.
It would be great to watch videos of these creatures evolving around different obstacles with different survival criteria.
I honestly think you have a killer channel here, with an opportunity to also stir interest in this field.
I wish you the best.
But please... more videos.
David , you have had two and one half million views in less than 2 years. That should tell you that you are very good
at mtaking a complicated subject and explaining it in a way that people will listen to. It is a shame that you called it
quits.I for one wish you had not made that decision. Best to you and thank you for all the effort and work you put in.
I was so disappointed when I went to his channel and couldn't binge years worth of content...damn it
he quit? whered you find that info? did he say why he quit?
Men in black took him in as a researcher. Now doing top secret work.
"two and one half" never understood this americanism. wonder if you ever say "two and two halves" or "two and three halves"? plus it just sounds wrong
@@artanaillazentujin3449 he only has 2 videos on his channel and hasnt posted in 2 years, pretty safe to say he either quit or died or something
So this guy came out here and dropped this absolutely banger of a video, got 3M views and 40K subscribers and said “I’m out!”
I was hoping I could binge a ton of his videos. This was so captivating, entertaining and educational!

The radioactive example is the most fascinating one to me due to the complex yet uniform nature of the movement. Plus, there are still individuals who deviate from it and survive!
Incredible video, sparked a bit of interest in me about simulating evolution
This is one of the best videos I've ever seen on youtube. And that's a lot. CONGRATULATIONS, amazingly well explained, programmed, everything. You can be sure that I'll share it as much as possible. Keep going!

"and it also has to be sufficiently socially adept to find a mate"
ok man, there's no need to attack me like that.
memes aside, this is a super fascinating video, i have skipped a total of 0 seconds.
Being socially adept to find a mate, if included in the simm, it would yelled much different results in the Kill switch simm.
Sad fuck
This is my favorite TH-cam video. Period. Incredible stuff.
Not exaggerating: The best video I have seen on TH-cam so far
This was great to watch. I'm really glad the algorithm worked in your favour. I wish there was an easily approachable way to try out your software, as a microbiologist I am not that versed in getting stuff to run on linux. In any case, this is a great video, your narration and explanations are awesome :) Thank you for all the effort you put into this
Don't you mean this was "great great great great great great great great great great great great great great great great great great great great great great great great great great" to watch?
worked in his "favor"? Shouldn't it be subjective, unbiased??
I’m sure there will be iPhone apps for this in a few years
@@Ty-mf3vz the term worked in someone's favour doesn't imply that it isn't subjective or unbiased. It means exactly what you want it to mean. It basically means that despite the inherent randomness he got lucky that it worked out the way it did.
@@Ty-mf3vz Unbiased? What makes you think the TH-cam algorithm is unbiased? In fact, they make a point of telling us of at least some of the biases they employ.
This is a very nice and interesting insight into evolution. I don't find it surprising though, that the kill neuron soon predominates the respective simulation. David accidentally incentivized killing contemporaries. The reason is, that his populations have the same overall size from generation to generation, but only survivors do reproduce. This means, that if fewer entities survived, the survivors will create more offspring (per survivor). So by killing others, his entities have more offspring, while reducing the offspring of the competition. It was unavoidable that his little creatures became murderous :) - on the plus side: Different environmental conditions (like in the real world) would incentivize different behavior, and thus not have this drastic an effect.
I was sort of wondering about the reproduction factor too! Like what if the population is allowed to grow/shrink based on the number of survivors at the end of each generation, rather than entirely repopulating the beginning of each generation? It seems to me that this would have a significant impact on the applicability of the simulations' outcomes to nature.
But then, I also see the advantage beginning each simulation with a standard population size. It just makes things so much cleaner and easier to compare, not to mention keeping CPU usage manageable. And I guess you can think of them as samples of a larger, unsimulated population? I feel like there's something wrong with that view but I can't put my finger on it.
Super interesting video though! Makes we want to try all sorts of different configurations
The real world almost certainly favours other traits than killing, until congestion happens.
Unfortunately, direct cooperation is many tiers higher up in orders of required logic, and can therefore be preceded by the occurrance of congestion.
I see this more as a clear simulation of intelligent design. unless this program wrote itself.
Poor guy is doing a simulation that proves the value of death, yet it is lost on him.
What he should do is give the creatures compassion and hatred and then hardwire them so that hatred and, ultimately kill signals, are generated proportional to the product of the creatures compassion, the genetic similarity of any death in front of it and are directed at the assailant.
Then he might learn something. We might all learn something of highly contemporary value. Because, nothing spills more blood than a bleeding heart.

For real, is any of the comments on this comment real?
You sir are truly a man of science. Your knowledge and attention to detail show profound wisdom. For example, while talking about your postulates for evolution you mention self replication. Over the screen you have a floating hydrocarbon! The molecule theorized to have given rise to cells and isolated organic environments. I have worked in a molecular biology lab for a few years now and I salute you.
That was amazing to watch, Thank you for programming This!
"Those who don't [reproduce] were just unlucky with mutations, and they don't have the brain wiring to know how to make it to the spawning areas"
And i took that personally

I loved this video, have watched it several times! I would love for you to do a similar experiment but one that forces multicellularity, like with volvox, where they develop the ability to stay together. Or with an obligate symbiosis where you start with separate strains (Like a bacterium and an algae.) Even better would be aminoacid strains developing different functions.
your voice is so davedamn soothing i might fall asleep to it
Oh my god this is the coolest shit ever. This would make an incredible video game. Instant subscription
Not exactly a video game and I'm not sure how much/where it is still available but there used to be a pretty neat 3D evo sim called 3DVCE that evolved 3D creatures composed of evolved physical bodies that moved with simple, evolved neural networks. The selection options were pretty limited but you could get some really really interesting results if you ran the sim long enough.

30:41 Nice
I initially thought that making the output neurons do explicit actions felt like cheating, however since the connections are chosen by the creature and they have to determine usefulness for themselves this is actually perfect!
a great video would be just more scenarios, especially ones that change survival requirements at some part of the way through
also, the radioactivity should make mutation frequency increase! so many possibilities!
