Sounds like a pop-sci summary of complex issues. Throws things around like 'no living descendants' of Neanderthals, except for half of us that still have their genes? What else does it take, to be a descendant? And 'left the caves' which is a folk story. We have evidence of really ancient peoples in caves, and evidence of more modern ones everywhere. Why? Because 'they left the caves'? No, because older evidence outside caves degraded because, well, they weren't in caves which are stable cold-rooms for preserving whatever is in there. Include perhaps some exceptional individuals who chose to go there (and die there). No reason to believe there was any special cave-preference at any time in history. Anyway, I quit reading there.
