But findings over the past few years — and a re-examination of old ones, such as the mastodon rib — have shown conclusively that humans reached the Americas well before the Clovis people. That has sparked a surge of interest in the field, and opened it up to fresh ideas and approaches. Geneticists and archaeologists are collaborating to piece together who came first, when they arrived, whether they travelled by boat or by foot and how they fanned out across the New World.
Thought this was interesting, although on the evolutionary scale I guess. So, who got here first?
