"Something seems to have happened around 50,000 years ago, shortly after which all other species of human such as Neanderthals and the so-called Hobbit died out."
Isn't the current estimate, that Neanderhals and Danisovans died out around 45000 years ago? Or does he refer only to the region of the cave? And the Homo floresiensis died out 10000 years ago (or 100 years ago, or he still exists, if some Anthropologists are right).
And what I do not understand about the cave archeology: nobody who lives as a nomadic hunter & gatherer lives in a cave. The climate inside is near unbearable if you are accustomed to free air. Maybe one can stay a little time in the mouth of a cave. When the weather conditions outside are as ugly as they can get. Or if the population density got so bad, that an easy to defend place is necessary. The findings IMO are more probable a result of population dynamics than brain development.
