Americas earliest Humans?

The Clovis people, known for their distinctive spear points, likely were not the first humans in the Americas, according to research placing their presence as more recent than previously believed.
Using advanced radiocarbon dating techniques, researchers writing in the journal Science on Thursday said the Clovis people, hunters of large Ice Age animals like mammoths and mastodons, dated from about 13,100 to 12,900 years ago.
That would make the Clovis culture, known from artifacts discovered at various sites including the town of Clovis, New Mexico, both younger and shorter-lived than previously thought. Previous estimates had dated the culture to about 13,600 years ago.
