very intresting. txs.
It sound reasonable that language variation stoped, I do not see why all things that evolve have to do it either at the same speed, or at the same acceleration rate.
The epigenetic and the genetic evolution in a species Seems to be analogous to the evolution in one human regarding the neural circuits and the environmental factors.


Death, especially early death, is a powerful stabilizing force. A culture that can simply be transmitted but not significantly increased, because it depends exclusively on individual acquisition, can only reach a given level. Technologies of cultural transmission take long to develop in such a society. But once they are established they serve as a foothold for progress to a further level. Take for instance navigation. Or agriculture. Or architecture. Or, perhaps especially, writing, which expands cultural memory beyond the individual's life.
