First I'd like to start by saying that I am by no means an expert on evolution, so take everything I say with a massive brick of salt.

Regarding...
Real organisms have additional selection criteria. Like, are pretty girls more capable of surviving? No; but they are more likely to reproduce.
Real organisms have no selection criteria whatsoever, it is their genes that have selection criteria.  Otherwise homosexuality would not be so prevalent in most all species.   Richard Dawkins' "The Selfish Gene" is a good read on this.
All genes undergo the same selection criteria, namely their success at replicating.    So genes that build prettier girls are going to outcompete those that build uglier ones.  And of course --as meep-eep mentioned-- the genes that produce a sense of aesthetics (which discerns "pretty" from "ugly") are also naturally selected.  But I digress.

Regarding...
They are beneficial, in that your AI's may 'speciate' and form populations which do not mix anymore because they are too different in internal structure.

Yep,  my system has that feature.  Read the link I provided in an earlier message for how the species are determined.


Regarding...
Also, they may learn not to mate with AI's that are just like themselves (incest taboo).

Very good suggestion.  It would be interesting to see if the cost of calculating relatedness for the purposes of incest prevention is worth the CPU resources.  Maybe it is better to have the occasional incest if it is much faster to compute.


Thanks for all the great feedback!!

While what you say is true, I think this distinction is irrelevant in this case. The genes are expressed in individuals.

Good, on the speciation front.
