“There’s this prevailing idea that as soon as human hunters crossed the Bering land bridge they had sticks with spears and went across the continent and led everything to extinction,” said Grant Zazula, a paleontogist with the Yukon Government.

”When we did our radio carbon dates on all these mastodons from the Yukon and Alaska, we learned that they weren’t even here by the time people showed up.”
