RE: Dumb & Dumberer: Why Are Human Brains Shrinking?
There is definitely the possibility of our brain connections getting better. The problem lies in that we don't have any actual brains from people 10 or 20,000 years ago to study and compare ours with. So we will not know that for sure.
Lemme ask you a question. If we don't have brains from that far back, how do we know they are shrinking so much from so far back?
