No, this article isn’t about the Kardashians. It discusses a genetic study which says that genetic selection for intelligence is slowing down in humans. Put another way, our more comfortable surroundings and mate selection based on factors other than survival ability has slowed the evolution of the human brain.
It doesn’t mean we’re getting stupider, despite evidence to the contrary presented daily on various reality shows. Its not talking about knowledge or cognitive ability at all. The study seems to say that the rate at which we’re developing brain capacity is getting slower because there is less pressure from the big bad world to evolve (and eliminate harmful genetic mutations).
“A hunter-gatherer who did not correctly conceive a solution to providing food or shelter probably died, along with his/her progeny, whereas a modern Wall Street executive that made a similar conceptual mistake would receive a substantial bonus and be a more attractive mate. Clearly, extreme selection is a thing of the past,” the researchers write in the journal article.
A different kind of scientist put it this way:
removing the pressure for everyone to be a superb hunter or gatherer may have allowed us to evolve a more diverse population with different types of smarts
