> How is darwin’s point and the plantaris muscle an example?
The plantaris muscle no longer exists in 9% of humans. Darwin’s point is missing in 90%. Both exist at 100% in all our nearest relations, so they’ve been more or less slowly breeding out of the human population as we no longer need/use them. The extrinsic ear muscles, that are only able to slightly wiggle the ears, and that only in a subset of humans, would be another fine example.
You aren’t understanding my post. I wanted to see evidence of anatomical changes IN THE LAST 2 OR 3 THOUSAND YEARS.
Not millions.
Human teeth are changing just in the last 10 or 20 generations. that’s 3 to 5 hundred years. Get it?
tHere’s no indication that the percent retaining darwin’s point has declined IN THE SLIGHTEST in the last couple thousand years. At least not in this article. ditto for the leg muscle.
What is the survival value of wiggling one’s ears; what is the selection pressure behind it; please quantify?
