@gutenberg_org I read 'Human League' at first. Thought I'd stumbled on a shitpost

@gutenberg_org "Language was the trigger for modern human behavior,” says Miyagawa. “Somehow it stimulated human thinking and helped create these kinds of behaviors. If we are right, people were learning from each other [due to language] and encouraging innovations of the types we saw 100,000 years ago.”

@gutenberg_org I would have guessed much longer -- at least as long as our sub-species has been around (200+ky), and likely longer. There'd be little no available EVIDENCE of that now, nor should we expect it, but I think it's a very reasonable supposition to make.
