10. "when two ice sheets covering much of North and South America separated"

Really? There was an ice sheet, 15,000 years ago, covering much of South America, over the equator, and it had been joined to that in North America, so that Central America had an ice sheet on it too? Sound unlikely to me. This looks a fairly typical map of ice in the last glacial period:

There's a few thousand miles between the ice sheets there, and I don't think they were ever linked.
