Simulating physics of muscles/skeleton structures has been done many times over, and I feel like the focus on eyes and vision is what makes this one interesting. Anyway it's quite a fun category of youtube video: https://www.google.com/search?q=simulating+evolution+muscles https://www.google.com/search?q=simulating+evolution+muscles They tend to be two-dimensional or have other big simplifications. I guess trying to evolve a "real" organism explodes in complexity very quickly even if you ignore the "brain".
