Creatures Demo

Thanks for your interest in this video, I'm just posting a commentated version of the same video, than explains wots going on.
wemustdissent, has posted some accurate information above, thanks :)

to get a different trait you can change the computer represintation of the enviornment. This technique is used by engineers for real world applications.

The ones that are better at getting from A to B survive while those that cant die off. Thats all. After many generations you get "organisms" that can swim.

evolutionary computer programs work the same way evolution works. They set up an enviornment like "underwater." They set up a goal like "get from point A to point B" (in nature this "goal" is set from survival competition) then they start with a random shape like a box and have the box "mutate" its shape completely at random. This box then "mates" and splits into generations and those boxes mutate and mate and split.

I need an explanation. I have no idea what's going on... but it's interesting.

are those creatures the result of evolution or have they been designed?
anyway, great work!
