I don't see any evidence of evolution programming in this video. It looks like at each generation you are given a stock list of attachments to your creature, and then the computer creates an environment for the creature which is compatible with it (ie if you make a herbivore, there will be plants around for you to eat, and if a carnivore, animals around that are slow enough for you to catch and eat). It looks like every characteristic of your animal is chosen by you. There's also a godlike aspect to this, since you are buying them buildings, musical instruments, weapons, all which influence how the culture develops. I don't think the game would do anything if you don't interact with it. You have to propel your little animal around to make it catch and eat prey, for example.
