Attention aspiring thrive zoologists , heres a fun exercise for you

Catalog the AI evolved species in your save games and post them here. Observe their behavior, catalog that too.
I did something akin to this when we were still developing 0.4.0.
It will be very fun to see what evolved in everyones saved games :smiley:

It will be especially helpful/interesting if you catalog novel behavior, like what scarlet seeker saw in his video. Where a species evolved ambush hunting behavior.
This will aid us in improving things in the future.

It is nothing very spectacular, but after 1300 Million years (13 editor cycles) of bacterial evolution on one of my playthroughs, I noticed a species called Vruhxes Otappian on the surface biomes. They are photoautotrophs and have a strong silica membrane.

What I found interesting is their extremely sessile (and “brave”) behavior: they seem the bacterial equivalent to plants on Earth. Even though my cell is armed with a pilus, and standing right next to them, they don’t move an inch. When I attack them, sometimes they would flee in the opposite direction for a second or two and then stop again. Other times, they would remain totally still until being killed.

On the subsequent editor session, I could check that they are performing well according to auto-evo. I can see why: even though they are easy prey, there’s plenty of energy available for them in the form of light. Their role on the environment is also very important: they are the main source of glucose for the other species, now that free-floating glucose has almost completely disappeared.

I find it very interesting to observe the complementary roles of “producers” and “consumers” emerge and develop naturally from the evolution algorithm.

After a couple editor cycles, the Vruhxes genus have developed a pilus and seem now more aggressive, sometimes even confronting my cell, being more capable of defending themselves.


Thats awesome Interesting that they became more aggressive.
