The results are surprising.


It seems man was around long before the clovis in North America.

So much for the young earth theorists.

The timing of humanity's presence in North America is important because it plays into the debate over why so many great beasts from the end of the last Ice Age in that quarter of the globe went extinct.

Not just mastodons, but woolly mammoths, sabre-toothed cats, giant sloths, camels, and teratorns (predatory birds with a nearly four-metre wingspan) - all disappeared in short order a little over 12,700 years ago.
