Thanks for posting this. It has always baffled me that we are led to believe that all of humanity springs from one common root. Absolutely ridiculous and goes against common sense -what other species (of anything) has just one single representative??? Who's been selling this and why???
Nobody is saying there was a single pair of people at some point. But something like a population bottleneck resulting from the Toba eruption would mean all future people were descended from a small group of survivors.
