Woolly mammoths' last stand before extinction in Siberia wasn't made by natives - rather, the beasts had American roots, researchers have discovered.
Woolly mammoths once roamed the Earth for more than a half-million years, ranging from Europe to Asia to North America. These Ice Age giants vanished from mainland Siberia by 9,000 years ago, although mammoths survived on Wrangel Island in the Arctic Ocean until roughly 3,700 years ago.
"Scientists have always thought that because mammoths roamed such a huge territory - from Western Europe to Central North America - that North American woolly mammoths were a sideshow of no particular significance to the evolution of the species," said researcher Hendrik Poinar, an evolutionary geneticist at McMaster University in Hamilton, Canada.

DNA Shows That Last Woolly Mammoths Had North American Roots"Migrations over Beringia [the land bridge that once spanned the Bering Strait] were rare; it served as a filter to keep eastern and western groups or populations of woollies apart, says Poinar. "However, it now appears that mammoths established themselves in North America much earlier than presumed, then migrated back to Siberia, and eventually replaced all pre-existing haplotypes of mammoths."

"Small-scale population replacements, as we call them, are not a rare phenomenon within species, but ones occurring on a continental scale certainly are," says Ross MacPhee, curator of mammalogy at the American Museum of Natural History, and one of the researchers on the study.
