- numba888 2y ago> Two studies published in the latest issue of Science have revealed that birds, reptiles, and mammals have developed complex brain circuits independently, despite sharing a common ancestor. They didn't show those 'complex brain circuits' were not present in common ancestor. Am I missing something and this is well known? There is also nothing about fish. I suspect such complex organisms cannot exist without "excitatory and inhibitory neurons" the article talks about.
