Clovis People not the first American settlers, study finds

The Clovis People, a prehistoric group of mastodon hunters distinguished by their unique spear points and once thought to be the first Americans, likely populated North America after other humans had already arrived, a new study concludes.

The Clovis and their hunting technologies were not the first inhabitants of the New World, researchers write in the Feb. 23 issue of the journal Science, addressing a longstanding debate on the first New World humans.
