doesn't cut it.
A 22,000-year-old mastodon skull and tool dredged from the seafloor in
the Chesapeake Bay hints of early settlers in North America.
From what I've read over the last few years, especially due to finds in Central & South America, the land bridge theory has been in trouble for a while, both on the 'how & where' and the timing. Add in the political fallout of showing early American arrivals from places other than the generally-accepted, and it'll be a while before this can be settled.
