There’s also a growing body of research that indicates a comet impact is what triggered the end of the last ice age, which would very well have caused massive floods. Randall Carlson has a lot of fascinating theories in this area.

- ncmncm 6y agoWe don't really know much of anything about the pre-historical population of the Americas. E.g., only one unambiguous Clovis skeleton is known. We have certain knowledge that the Amazon region was heavily cultivated ~10,000ya, which would have required substantial population. A lot can happen in a millennium or three. Also, there is evidence of multiple extinctions in South America and South Africa at the same time, and of a strike in Syria. I don't think we have evidence yet to determine a bound on the range of effects.
- eloff 6y agoWe know North America was mostly filled with hunter gatherer tribes. So the population would have been low compared to even South America, but especially Europe and Asia. We don't know all that much about the supposed impact, as you say. Just that more large mammals in North America went extinct than anywhere else, so it was likely the worst affected.
