Originally posted by @duchess64I didn't ask him directly, but it looks like his research does not necessarily support this prediction. I'm guessing it was part of a larger interview in which he qualified it in some important ways. More info is needed and I was asking if you knew what it was. His research seems to based on mechanisms that maintain overall genetic diversity.
"Bruce Lahn, a geneticist at the University of Chicago in Illinois, has reported
evolutionary changes in the brain, caused by two new genes involved in
brain growth that emerged around 37,000 and 5,800 years ago."
""I'm confident that unless we go off and colonise some other planet, we
could come back in 5,000 years and people would look much the sa ...[text shortened]... abilities," he says.
Why doesn't Wildgrass ask (or troll) Chris Wills? It's his prediction.
I don't know why you would post this if you didn't want people to think about it. To me, mankind seems to be thriving on earth from an ecological standpoint. Aside from a near-apocalypse, I cannot envision a scenario where human intelligence significantly evolves from it's current state. Maybe social media has changed the way we think about human relationships. Elon Musk has stated that we are already ostensibly human cyborgs, in that our brains partly exist in our computers and cell phones. Finding a partner to raise a family with requires a different set of skills than it used to. Will this societal change lead to an evolution of intelligence?
The basic premise of your argument is still true though. There is evidence of recent human evolution. That's why I asked you, not Chris, what might be a plausible mechanism for the evolution of human intelligence.
