Story highlights new study examining the tusk of a woolly mammoth that lived about 17,000 years ago. Amy Willis, a core faculty member in UW Biostatistics was a member of the international team that uncovered details about the animal's activities from birth to death. The team retraced its footsteps across Ice Age Alaska over 28 years, marking the first time scientists have been able to reconstruct a mammoth’s life history in such fine detail.
