Medical research shows we retain fish brains & reptile brains within our mammal brain does it prove evolution?

Not on it's own. The fact that so many structures have been retained and modified is a good hint. Observing the commonalities of their embryonic development goes a step farther. Observing the commonalities over a vast range of vertebrates worldwide, and observing the pattern of variations shows a branched pattern of development, the phylogenetic tree, which indicates descent from a common ancestor.

You got "medical research" confused with "Art Bell" again. Click your medulla oblongata forward! I wonder where the "fish switch" is? For the absolute best proof of evolution, watch the "Planet of the Apes". To-date nothing beats it for proving evolution, not kidding, it is the very best evidence evolution has.
Reply:Not necessarily, it is merely a truth about the structure of our brains *per se|*








In the human brain is a hierarchical structure|





In something like the core, is the *reptilian brain|* That governs basic urges such as sex, territorial, aggression, fear and that sort of thing|





Built upon that is the *mammalian brain|* This governs things such as emotional affection| That is why a cat or a dog can love you with affection, but a reptile cannot| A mammal can love in that way, but the only thing that a reptile has in an *appetite|*





Built upon that is the brain that governs our *higher reasoning processes* - that concerning rational thought and deliberate choice| It is precisely that which makes us distinctly human from the lower animals|
