rudimentary (old) evolution does only care about survival but for "newer"(?) evolution it's a solved problem. so "it" appears as if to care about other things.

rudimentary (old) evolution does only care about survival but for "newer"(?) evolution it's a solved problem. so "it" appears as if to care about other things. it's not quite correct to contrast 'rudimentary or old' with "newer". I think it's more reasonable to think of it as more or less fundamental to life. closer or further from basis survival
