Kome: This is actually a major issue in neuroscience research that uses animal models. Humans didn't evolve from any species alive today - we share common ancestry. Which means that once the ancestral lineage split, each species continued to evolve in their particular niche. That would, and does, have much more drastic effects on neural ontogeny and phylogeny than a lot of modern researchers give thought to.From the level of the macrostructures of the brain (e.g. the frontal lobes, the visual cortex), to the way down to the density and types of neurons at a particular location (e.g. pyramidal cells in the cerebral cortex), to the way various neurotransmitters and hormones affect brain functioning (e.g. the rule of dopamine in memory formation), no matter how similar two species' brains are anatomically or functionally, that doesn't mean they are the same and we can learn about one with strong precision by studying the other primarily. Best case scenario is that animal models give us a highly probable and very likely idea of how things work in the human brain and can lead to the generation of new ways to study the actual human brain.Don't get me wrong, animal models are necessary in neuroscience, medicine, and so on, but the take home lesson that some recent research has concluded is that we need to be very cautious in how we generalize findings from chimpanzees and rhesus monkeys to humans (and, for that matter, vice versa). Much more cautious than we have been in the last few decades.Of course, I catch a lot of crap from my research colleagues for just how conservative I'm willing to draw conclusions in my research. So perhaps the view I have on this is a bit too stringent even for science.

Pants full of macaroni!!: But the brain doesn't evolve unless the tinfoil of Evolutionism keeps God out of its brainwaves. Or something./summon you-know-who
