A BBC report about the the Toba volcanic eruption that sheds new light on the human response during the winter that must have followed and its effect on human evolution.

This appears to run contra to previous ( conventional) thinking

In looking into the background of this report I came across an excellent paper, "Late Pleistocene human population bottlenecks, volcanic winter, and differentiation of modern humans". Although this paper is two decades old it gives a clear picture of the landscape of competing ideas into which the Toba eruption global winter and its impact on humanity, was inserted.

While doing this speedy literature search I ran across another  paper, from about five years ago, that also cast serious doubt on the Toba Eruption/Bottleneck connection. Life being what it is I can no longer locate it. If I find it during a further search I'll post a link here.

Thanks for the cooperation. +1

I think science sites work best that way.
