Thanks very much for this. I did the quick flyover (eithout added material) and was rather surprised byt eh recentnes of Tmbora, as well as by the fact that all 6 continents had human communities a long, long time before theadvet of agriculture, which they have pegged as 8,000 - 10,00 years ago, with the retreat of the most recent planet icing.
I belive "Mitochondrial Eve" would have been way, way before that, maybe a milion years ago, and she is -- by some hypotheses --- the ancestress of all human groups presently represented on the planet. This hypotheses is based on the mitochondria in the ovum (sperm have no mitochondria), hence a method of tracking through the female line. But I'll have to look that up.
Thanks again for the good info.
