In this story about old human feces found in a cave that may give some clue as to when human first migrated to North America, I noticed this:
Humans are widely believed to have arrived in North America from Asia over a land-bridge between Alaska and Siberia during a warmer period. A variety of dates has been proposed and some are in dispute.
What kind of SUVs were they driving back then to cause such warming?
