the neurological ones. We sometimes seem to forget that our brains are as much a product of evolution as the rest of our bodies, as if somehow the brain was derived from a different process than produced that enlarged cranium that contains it. Plus, it’s one thing to understand the history of the amygdala or the hippocampus, and something else entirely to understand the evolutionary underpinnings of something more nebulous, like imagination.
Curiosity is a peculiar mixed blessing. It can lead to great discoveries and improvements, but it can also be decidedly dangerous and lead to situations for which we are not in any way prepared. Although not unique to humans, humans take it further than any other species on Earth has. Yet from an evolutionary perspective, the urge to explore does not always make sense.
