We are talking apples and oranges. The first hominids apparently did emerge in the range of 2 to 4 million years ago.

There was some catastrophic event now theorized to be a gigantic volcanic explosion that encircled the earth and almost wiped out humans between now and 450,000 years ago. The theory suggests that all of the few thousand survivors were descended from one woman whose mitochondrial DNA we all share.

Apparently Yellowstone Park is the site of a one such past volcanic caldera. The Discovery Channel show on calderas is very good, and scary for anyone on the North American continent - yes, that degree of catastrophe has occurred and will occur again, according to Discovery. The show was just on within the last week. Keep an eye out for it; they do a lot of repeats.
