On the contrary, once you start digging down into details, you'll see living things made of multi-purpose components with fuzzy boundaries, going very much against "single responsibility principle" and the like. That's because evolution isn't like human engineers, who need to walk up and down the abstraction ladder so things they care about fit in their head. Evolution is brute-forcing the problem space, using a greedy optimization algorithm. It doesn't need to remember anything.
