accelerated!!! not excellerated! (sheesh) evolution = puctuated equilibrium?
I dunno. I had a Siamese cat that used to come up to me and meow in full sentences about what was going on around the house — “The kitten took a crap in the laundry room, our water dish needs refreshing and not just refilling, there was a bug crawling up the wall but I killed it, us cats want wet food frfom the can, and it’s cold so do that thing you do to turn on that thing that makes our fur warm.”
Molecular techniques then revealed that these changes occurred around 200,000 years ago at just the point at which modern humans were evolving. This has led to much speculation about whether FOXP2 is a gene for speech particularly given that people with major mutations, like the KE family, have major language defects.
Cool!
The genetic change for the development of language is now being placed about the time modern humans developed as well.
I was never comfortable with that 50,000-60,000 estimate for language development.
