A member asked:
Hi docs, is it true that people are constantly evolving, or are they just not getting smarter and devolving instead?
A doctor has provided 1 answer
Whoa: Your instructor needs to review what evolution is all about. It's not going in one direction, and it's not directed toward any "perfection". In fact, there are folks who argue that present trends select for dumber, rather than smarter, folks. We underwent natural selection for larger brains, speech, and adaptability 100,000 years ago. I suspect little change in the brain is in the offing.
