I wonder what the energy/evolutionary cost of densely-connected brains is. If it's advantageous, why are crows exceptional?

- xeonmc 4mo agoMaybe they require the equivalent of advanced EUV machines to make?
- IAmBroom 4mo agoIt could simply be an evolutionary "discovery", with no particular advantage over our "brain model". Evolution doesn't seek out optima; it simply encourages genetic structures that improve odds of reproductive success. Or, to put it another way: if corvid genetics happened upon a brain type that promoted their survival, it doesn't matter if it was "better" or "worse" than the path the monkey/hominid brains took. Genetics took the first bus going in that direction.
