Am I right that the common ancestor of sapiens and Neanderthals and Denisovans is -800kya?
And what about the following strong differences between sapiens and Neanderthals/Denisovans: musical instruments, cave paintings, projectile weapons?
I found that the basis has to be there from a long time ago, and one branch makes use of it. The lungfish has limbs, but only some branches of it went terrestrial. An old human ancestor had language capabilities but only some branches used it. Dinosaurs had feathers but only some used it for gliding and flight.
Can you comment on the shrinking brain size that’s observed among humans in the past few thousand years?
