Why are you spending your time defending the least useful parts of your field? You’re just making it sound more and more like people taking findings from neuropsychology (a science) and making historical guesswork around it (trying to guess what caused changes with zero evidence of how animals behaved in past environments). I’m aware of phylogenetics, but it seems to lose it’s usefulness when most genes have such a weak correlation to behavior and when you can’t actually observe historical behavior. Brains have too high plasticity to predict why a certain region would exist if you don’t know the environment the animal lives in.
