why is it that so many animals have their brains in their head, rather than anywhere else in their body?
In: Biology
A lot of people have made really good points about the brain being closest to the sensory organs, and that’s very true, but it’s also worth mentioning that the vast, vast majority of vertebrates are fairly closely genetically related, and working from the same rough blueprint. Head with all the sensory organs, thinking parts, and eating parts at one end, waste disposal at the other, and some number of appendages for mobility. It’s a working blueprint for creatures with hard internal skeletons, so there hasn’t been a lot of evolutionary push to shuffle the important parts around.
