I programmed some creatures. They Evolved.

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.

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!

[@olarmariusalex]

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.

[@Boris99999]

@@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!

[@ern0plus4]

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).

[@__-op4qm]

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.

[@chrishamilton1728]

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.

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.

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.

[@mike_o7874]

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.

[@mosquitobight]

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.

[@ItIsCoMpLiCaTeDsTuFf]

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

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

Beautiful simulation of cause (genetics) and effect (neural networks) to create some intriguing scenarios. That gene to NN was brilliant.

[@Laezar1]

40:45 One interesting thing is that in reality, neurons take energy to use so they increase the needs of the organism. And as you shown in the exemple there is diminishing return when it comes to the result of increasing brain size. The smallest brain size was awful, but just a few neurons were enough to make it almost as good as the biggest brain. This probably is one part of the explanation why most organisms in nature are extremely simple. Only the most successful creatures with bigger brain benefit from it, while smaller brains require less energy and have less pressure to succeed. It's obviously more complex than that but there is definitely a tension between the cost and benefit of brain size. While in your simulation if brain size could evolve alongside brain structure (a gene causing extra genes or neurons to appear in the next generation) there would probably be a complexity creep that would never stop because there is no limit to growth, at least until it becomes unsustainable and crashes your computer and oh my god this became a global warming analogy! Except that in this case they would rip the fabric of spacetime without even having any way to realize they have an effect on it. Creepy...

An interesting related idea is the observation that brain size changes tend to lag behind body size changes, that is to say, if your body is growing in size over evolutionary history, your brain size doesn't increase at a proportional rate. This had led to the hypothesis that reduction or gain in body size primarily leads to disparities between brain and body sizes. I seem to recall reading about size reductions in our primate evolutionary history for instance. Non-migratory birds tend to have more encephalization when compared to migratory birds - likely because nervous tissue is too energetically costly when competing with similarly expensive migration patterns where birds might have to fly thousands of kilometers. Our large brained non migratory birds dont have to worry with competing costs, they just need to support their larger brains. It's hypothesized that larger brained birds are more behaviorally flexible and can capitalize on niches that aren't available to smaller brained individuals. This would stratify where certain individuals of a species can survive (based on individual brain differences), acting as a soft reproductive isolation. Which may have contributed to the diversity of avians fauna today

38:32 oh my God. I think that's a primitive form of memory. I was thinking about the loop in the first run how the internal neuron had a negative loop to itself. I intuited that it was basically a flipper that flipped the neuron back and forth so that it wojld move randomly every other step. This seems to basically remember what it did for the last 2-3 steps. It's got the same negative self flipper but it also inverts itself into the neuron linked to thst sensor. N1 basically inverts itself every step while also adding influence back to N0. Which means certin locations of x over time will do different things, depending on the cycle. Basically it alternates between moving west and moving random, but not every cycle. Usually it will do this 50/50 but the higher Lx gets, the stronger the strength of each subsequent flip will be. But N1 also inhibits N0 so it only really does this every other step. OH! Because it only wants to strengthen it when it's already strong, otherwise it would become neutral on the off cycle. Brilliant! I see that Rnd (random?) is linked to move random. So basically the stronger N1's flips are it will eventually overpower Rnd and move west more often instead of random. Or if Lx is shrinking, it will move random more often than west.

[@jessefinnerty430]

@@Dnallohes They're just there to be generic intermediate nodes that are able to connect to each other and pass signals around. Just having them available for this increases the number of different possible ways that the input signals can flow through the brain and be linked to each other, and therefore the possible complexity of the AIs behavior. If you're familiar with electrical engineering, you'll see quickly that one of the things neurons can do, just by being connected to each other in certain ways with signals going through them, is form various kinds of circuits, including things like logic gates (AND/OR/XOR/NOT, etc), timers, and memory circuits. The signals from the inputs going through these circuits allow the neural net brains to hold and act on more possible informational states, process the inputs in more complex ways, and even learn to correlate them (since the internal neurons can connect to each other as well). The more neurons & connections available in a neural network, the more complex its circuitry, and therefore its processing, can ultimately get. It can develop memory, learn to recognize patterns, adapt to changing conditions, get and use feedback on the sensory results of its previous actions, etc, ALL just depending on precisely how the neural circuits in its brain are connected. The neat thing is you don't have to understand what it's doing or program the neurons to do any of this, just let them connect however they want and mutate randomly. Over generations of selection, the successful surviving neural networks will become smarter and smarter (up to their capacity), evolving the right wiring to succeed (and/or call down SkyNet... but that's what you get for activating the 'kill' neuron...)
