Genome of American Clovis skeleton mapped: Ancestor of most present-day Native American populations

The Clovis people were not the first humans in America, but they represent the first humans with a wide expansion on the North American continent -- until the culture mysteriously disappeared only a few hundred years after its origin. Now genome mapping shows that some 80 percent of all present-day Native American populations on the two American continents are direct descendants of the Clovis boy's family.
