But at least one struck home, plunging through hide, fat and flesh to lodge in the mastodon's rib.
The hunter who thrust the spear on that long-ago day didn't just bring down the mastodon; he also helped to kill off the reigning theory of how people got to the Americas.

They convened a group of mammoth experts to conduct an autopsy on the extinct beast over a three-day period as the carcass thawed out.
However, frozen carcasses, like Dima and Blue Babe, (two well preserved carcasses described in his book, Dima is a baby mammoth, Blue Babe is a bison) are indeed desiccated and fully deserve to be called mummies." (Guthrie 1990) "Underground frost mummification should not be confused with freeze-drying, which occurs when a body is frozen and moisture is removed by sublimation, a process accelerated by a partial vacuum. I have often freeze-dried items, sometimes inadvertently, during our long Alaskan winters, where the temperature seldom rises above freezing for eight months of the year." (Guthrie 1990) "However, the desiccation of fossil mummies is quite different than freeze-drying.
Almost 14,000 years later, there is no way to tell how many hits it took to bring the beast to the ground near the coast of present-day Washington state.
As the ice caps in Canada receded and opened up a path southward, the colonists swept across the vast unpopulated continent.
Archaeologists called these presumed pioneers the Clovis culture, after distinctive stone tools that were found at sites near Clovis, New Mexico, in the 1920s and 1930s.
As caches of Clovis tools were uncovered across North America over subsequent decades, nearly all archaeologists signed on to the idea that the Clovis people were the first Americans.
In May 2013, scientists from the Siberian Northeastern Federal University heard that mammoth tusks were sticking out of the permafrost on Maly Lyakhovsky Island in nothern Siberia.
