Scientists say early Americans arrived earlier
A team led by two Texas A&M University anthropologists now
believes the = first Americans came to this country 1,000 to
2,000 years earlier than = the 13,500 years ago previously
thought, which could shift historic = timelines.=20 The team's
findings are outlined in a review article in Science magazine
= titled "The Late Pleistocene Dispersal of Modern Humans in
the = Americas," which synthesizes new data suggesting the
migration from = Alaska started about 15,000 years ago.=20
This theory is supported by not only archaeological evidence,
but also = from genetic evidence from living and ancient
populations, says Ted = Goebel, an anthropology professor at
Texas A&M and associate director of = Texas A&M's Center for
the Study of the First Americans. He conducted = the research
with Michael R. Waters, a fellow anthropology professor at =
Texas A&M and director of the Center for the Study of the
First = Americans, and Dennis H. O'Rourke, an anthropology
professor at the = University of Utah.=20
Previous theories stated that the first migrants spread from
Beringia to = Tierra del Fuego over a few centuries about.
Goebel says scientists have = concluded that the peopling of
America was a much more complex process.=20
The team focused primarily on molecular genetic,
archaeological and = human skeletal evidence to create a
working model that explains the = dispersal of modern humans
across the New World.=20
Molecular geneticists have used refined method and an
increasing sample = of living populations and ancient remains
to provide information on the = Old World origins of the first
Americans, the timing of their initial = migration to the New
World and the number of major dispersal events.=20
Archaeologists have found new sites and reinvestigated old
ones using = new methods to explain how early populations
