Simulating Evolution: Extreme Temperatures

[@kirbs0001]

Simulating disruptive ecological events such as droughts, climate change, ice ages, disasters, etc. might help periodically food-rich regions to evolve builds that can survive harsher but more stable conditions. It might even be reasonable to use it as a way to keep your sim from crashing; ie: focus disasters on areas with high pop density.

[@EightLittleBears]

That’s an interesting thought! Combat PC shortcomings with…killing 😂

[@StrawberryStickRB]

Oooo this would be cool

[@FloridaMeng]

I believe that's how you start a religion.

[@JerbilKonai]

Could even be explained by the argument that "if a tree falls and you don't hear it, has it fallen?". So if an event doesn't hit population dense areas, was there an event at all?

[@madeline6815]

I like the climate change idea! A way to scale the intensity of the seasons(maybe an average yearly temperature) would allow the simulation to model larger climate trends, ice ages and whatnot.

[@parmesanzero7678]

It’s amazing how many times I watch someone recreate Maxis’ SimLife and am fascinated each time because I always wanted a better/updated version.

[@EightLittleBears]

Glad you like it!

[@natebenham9603]

With the temperature changes you could have so water bodies freeze over allowing species to temporarily traverse them. Perhaps some way to evolve more unique traits like eusociallity, burrowing, and flight. Also some more diverse food options like carrion, ants, eggs, and honey. I've said this in other comments but what you're making is incredible. I'm trying to get into coding and I have no idea how you accomplished this.

[@EightLittleBears]

Thanks for the comment! I am hoping to add all of these things over time though I have to admit I hadn’t thought of using ice in that way following the temp changes. Really cool idea!

Could the change in weather create land bridges? I.e, two areas are disconnected, but if it gets too hot some water might evaporate, or too cold it might freeze, allowing for temporary passage between islands?

[@lorcogoth1]

you know it was really interesting to see that there was a repeating migration happening from the center of the map to the South-East corner of the map before dying off. looking forward to creatures being directly affected by Temperature that's gonna be interesting. anyway until then happy Christmas and New Year.

I love the content youve been putting out and I can't wait to see what you accomplish next year! From a data visualisation point - it'd be interesting to see meat split into active predation and scavenging. I'd love to know who is out there actively hunting and who is just eating whatever they come across on the ground.

[@EightLittleBears]

That’s an interesting idea!

[@skippofish2910]

I would really love to see you add a gene that controls mutation rate. Especially as you create a more volatile ecosystem it would be interesting to see what populations evolve to tightly regulate their genes and which don’t.

It’s in the plan. One of the first things I am going to do in 2024 is completely rewrite the code for stats and mutations to make it far more flexible, which should allow all kinds of new and interesting stats!

[@padraicbrazeau5251]

This is really cool I hope that you can add adaptations for creatures in relation to the environment, and add some kind of a plant that can grow in colder temps maybe make it grow slower as a way to balance the simulation

[@EightLittleBears]

Yeah looking into this (and thermal regulation in animals), not sure when that will be finished though!

[@ghosty918]

@@EightLittleBearsYou could include a plant evolution thing, with temperature regulation, a 'fruiting' ability (eaten by a creature with X stats, get spread for a growth boost in tiles based on creature's speed), and other variables. That way you arent just designating areas as the "poor resource zone" or creating functionally identical zones with different colored plants

[@Choompar]

Here's something to take into account, sleep. Some creatures will have to sprend most of the day doing nothing

[@herobrineharry7698]

Thermoregulatory adaptations, like Crassulacean acid metabolism, gigantothermy, insulation, and blood radiators (elephant/jerboa ears, etc), would really help emphasize the impact of seasons, and could allow for dynamic biomes in response to a global temperature change if you get the plant code efficient enough. You’d need to model that investment in increasing the efficient digestion and consumption of plants is likely to exclude predatory meat eating, and vice versa, to get trends comparable to historical- otherwise I think we might get Wooly Badgers, rather than Wooly Mammoths.

[@NerdyZanoth]

Super excited to see your next version.

[@FabioCarraturo]

First of all congratulations. This is one of the most captivating evolution simulations I've come across on youtube and it is beautifully done. Now, I realize suggestions for future improvements are plenty, but I was thinking that the avatar system might not be the best one to appreciate visually the diversity of each creature's stats and especially the continuities between related populations. Even though it requires sacrificing realistic depictions, attributing a single phenotypal characteristic expressed on a continuous scale to any given genetic parameter could be more helpful. For example the way stealth worked in the previous video allowed an immediate assessment of which populations invested in that parameter and which didn't, and it also allowed to guess the origin of a migratory population: if a new area suddenly showed translucent warthogs one could immediately conclude that they likely migrated from the population to the east which was more stealthy rather than the one to the west which was less stealthy. Similarly, just to make another example, creatures could come in two main colours based on speed with gradated variations in between two extremes, say red for slow and blue for fast (something similar to what Primer did in some of his earliest videos kzbin.info/www/bejne/Zouqk3yBmZWLqK8&ab_channel=Primer). The current system is aesthetically more appealing, but for example when a new population B arises from an older population A their respective appearances hardly allow to recognize their genetic connection and the graduality of this differentiation, as the system that assigns the avatars operates discrete classifications. Continuous visual characteristics could do the trick better when it comes to tracing relatedness and appreciating gradual changes over time.

[@EightLittleBears]

Hi! Thanks for the detailed feedback! Yeah I am thinking of some ways of getting the visuals to be more “informative”. stealth and size are easy ones but, like you say, it would be cold to have others too. At the moment I am thinking about outlines which change colour based on certain stats, icons, etc. I like the idea of avatars just because I like using real animals, so the trick is finding something that works in conjunction with that. I think the other thing to bear in mind is that (hopefully) as more avatars are added, they themselves will allow the tracking of movements and traits. If, for example, we had 1000 creatures to pick from, even minor variations would result in different avatars, etc. Thanks again for the comment!

soomething that may help with more migration, to access bigger parts of the map (and help in extreme environments): depending on perception value a creature can also see tiles that are further away and choose to go there if it makes caloric sense.

[@EightLittleBears]

I like the idea about perception. One thing I was thinking about was separating it out into different types, so sight would be short range but very precise, smell would (potentially) be more long range but less precise, etc.

Hi, I just found this project and I love it! I’m just curious what tools you used to build the visual simulation?

[@EightLittleBears]

Hi! Unity game engine (using C#) is the main tool. I draw all the creatures and stuff on an iPad using Procreate. For the charts in this video I just used regular spreadsheet software but in some of my other videos with moving line charts I use a chart-maker I built (again with Unity).

[@Cygnus_MC]

This is such a cool program, will it be available once you "finish" it?

[@AustinThomasPhD]

Very few evolution simulators impliment plant evolution, which is very important. Anti-nutritive compounds, in particular, drive a huge amount of specialization in herbivores and make omnivory or predation more viable .

[@goldenphoenix6500]

I can't wait to see how the simulation evolves next year! Do you have an estimate of when you think it could be ready?

[@Cassinia]

does this simulate resource depletion? if so, do the places that are consistently depleted take longer to replenish?

[@EightLittleBears]

Resources can deplete but this doesn’t (yet) have a lasting impact on the land itself (e.g. like you would get from re-farming the same crop every season on the same land).

[@thomassmith3020]

Maybe you could incorporate the fact that different food sources have different effort/reward values, cows have to spend their whole day eating, but tigers need to catch only one animal per week for example. meat has a higher nutritional value but is risky to acquire while herbivores take a safe but time intensive route. Also it would be very cool if you could get the predator prey population curves to naturally evolve.

[@erinkarp]

In the future do you think you'll ever consider procedural sprites?

[@EightLittleBears]

Yeah it is something I have been thinking about. The thing is that it’s basically a trade-off: - procedural sprites offer a better of what’s going on, and is generally the easier option since you don’t need to hand-draw every creature. - plain sprites offer higher quality art (because you can hand-draw shapes and lighting, etc.) and real creatures. I think I will end up doing both in the end.. haha

[@dariusgunter5344]

Amazing video series! Idk if you already implemented it, but I think you should include at least two more factors for animals, rest periods (aka how long do they sleep) where they can spend a round or more sleeping and conserve energy a lot of carnivores sleep most of their day, it would also help animals in colder regions as they can eat less and sleep more and the ability to gain stores of food, aka that they not only eat when hungry but to have more fat on them maybe an expansion to their hunger and the ability to move their food priority upwards. Additionally idk if you did that already but meat should give more calories than plant matter, mainyl because it takes less energy to digest and is directly helpful, but also because unlike the plants we eat most herbavores eat plants that are not very nurishing like grass, especailly when you substract the energy needed to digest the food meat is a much bigger plus. So maybe adjust the calories given by each food source too and see what happens it should lead to much more diversity in strategy (if you didnt do it already)

[@BananaBio]

Love you’re videos i have been watching since 1k subs❤ I have an interesting idea: add intelligence (brain) they can find ( things ) and if they’re smart enough they can use it example: they find a cave if they’re smart enough they enter it and get protection for some turn and more also this can implement the ability to swim if they’re smart enough or hide on trees many more thing’s its complicated to make so it probably will take some time to balance it but yeah GL with making intelligence

This is the most fascinating nature/evolution simulation I have found on KZbin thus far. How do you simulate reproduction? Can anything mate with anything? Do you separate species? Or have you made the (reasonable) abstraction of a-sexual reproduction?

[@EightLittleBears]

Thanks! Every creature has a “genome” which is essentially just a 61 character string. Every time there is a mutation, a random character in the string changes. Creature can mate with something as long as the string is ~95% similar (I.e. within 3 mutations of each other)

[@FranticFridge]

@@EightLittleBears Interesting, so your phenotype is basically independent from your genotype? This will lead to a lot of convergent evolution, where multiple species develop the same traits independently. I wonder if you would get more stable species and more robust populations, if you would link genotype and phenotype. For example by concatenating all your attributes into one long string and have that as your genome.

[@Jirodyne]

My first time watching one of your videos, and simulations. So got some ideas for next year. It sounds like you set it that coldness only effects plant growth. However, even in the most coldest places, there are still forests and animals. This is became a 'Tree', is not just a 'Tree', but like humans an animals, has different traits, effects, dna, ect, ect~. So even in the Tundras of the north and south, there should still be plenty of forests. Just a different kinda forest, with different trees designed to grow in the cold instead of just the heat. And being a different tree/plants, it could require a different kinda animal to eat it. One that is more adapt to the cold, but less to the heat. So eating it could effect the animal, making it more comfortable in the cold, and not like the heat as much anymore. This could cause 'Herb' like animals to split off into different zones they like or dislike, some in the middle where it's warm, while others in the cold cause they like the cold better. And having less food in the cold, they could digest food slower, and need less of it to get full. But, the effect only effects the Herb, so Predators can still roam the map to eat the animals without getting trapped in specific biomes cause of who they eat. ^ Just an idea to throw out there.

[@pmygamestemp2382]

You could over many turns change the terrain to see how enviromental change affects the population

[@EightLittleBears]

[@anthonycannet1305]

I think using temperature to strictly limit plant growth is the wrong way to implement things. Just because an area is warmer or colder doesn’t change plant growth, it mostly effects which plants grow there. A warm climate might have dense rainforest while a colder climate still has a dense taiga. The lower temperature does not mean less plant life until you get to an extreme where plants really can’t grow at all. In your simulation it appears that there is essentially only one kind of plant life (leaves, grass, etc. but all universally effected by temperature in the exact same way) so having it fluctuate with temperature is going to negatively impact your sim, you should either dampen the effect that temperature has on reducing available food in temperate areas or add a second type of plant that prefers the middle latitudes to maintain a more standard food availability and also allow for additional complexity in the species by diversifying their plant food source preferences

[@vincehomoki1612]

The most important thing is just to start. Focus on the fundamentals (80/20 rule and all that) and make a few small games in Unity (not to sell, just as learning projects). If you search for some of Blackthornprod’s earlier videos, he has some great tutorials for beginners. Even if they are a few years old, most of the stuff in them will still hold today (as it’s fundamentals). For pure coding I liked codewithmosh.com/p/all-access (if you have time one month you can easily blast through an entire course using the all access for $29 and then cancel - it’s great value imo).

[@sintanan469]

To keep from overpopulation crashing the computer, and the focus of animals driving towards one working build in a stable region, give plants a means to defend themselves. In our world plants will develop waxy surfaces, thorns, toxins, bright colors, odors, and more to attract a specific species or repel other species. Giving the plants a way to evolve might result in even stable climates to be more unstable and drive change in the animals... when the living plant is sometimes hostile, focusing on meat or dead/decaying plants may be the better option. Maybe plants in colder environments grow slower but develop richer nutrients or some way to preserve resources through the cold. Our real world does that with plants creating dense seed clusters or fruit to give offspring a boost to survive the temperature swing, and some plants develop ways to go dorment to survive winters. There are also other plants that develop some means such as flowers or odors to attract animals to help spread seeds. I guess what I'm saying is maybe the next step is to introduce evolution into the plants.

I think the world is not large enough to support a bigger diversity right now because any creature can just randomly walk in other regions and outcompete what ever lives their. and the simulation is not quite right just now even though the equatorial regions of a planet like earth are stable they are way to hot for most creatures and plants or have a extreme abundance of animals and plants because the temperature is stable but the moisture is not wich theirby causes the climate to be unstable as well because it is just a combination of both factors. But even then it is unstable not in time but in differing location because of wind and mountain ranges trapping mousture in some parts while keeping it away from others. The most overall stable regions are in between the equator and both poles. Wich isn't that obvious on planet earth because most of the space in between the equator and the south pole is ocean andthe only bigger landmasses like south america, australia, and most south africa happen to have mountain ranges on the wrong side of the continent by complete chance.
