Dakota Life - 10/01/1999
"""Telling Bones"" Dr. Timothy Heaton, of the University of South Dakota's Earth Science/Physics Department, finds clues to ancient human migration patterns in the sediments of a cave in the southern tip of Alaska. Since 1990, Heaton has been exploring sediments up to 40,000 years old. His findings include human remains that are 9,200 years old, along with the bones of bears, marmots, caribou, seals, sea lions, birds and rodents. His work is changing the way scientists think about human migration into the Americas."
