Texas A&M scientists say early Americans arrived earlier
March 24, 2008COLLEGE STATION - 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.
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.
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.
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.
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.
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.
Archaeologists have found new sites and reinvestigated old ones using new methods to explain how early populations colonized North and South America.

Anthropology Current Events and Anthropology News RSSSupervolcano eruption -- in Sumatra -- deforested India 73,000 years ago
A new study provides "incontrovertible evidence" that the volcanic super-eruption of Toba on the island of Sumatra about 73,000 years ago deforested much of central India, some 3,000 miles from the epicenter, researchers report.
Warm-blooded dinosaurs worked up a sweat
Were dinosaurs "warm-blooded" like present-day mammals and birds, or "cold-blooded" like present day lizards? The implications of this simple-sounding question go beyond deciding whether or not you'd snuggle up to a dinosaur on a cold winter's evening.
Hormone that affects finger length key to social behavior
The hormones, called androgens, are important in the development of masculine characteristics such as aggression and strength.
Inequality, 'silver spoon' effect found in ancient societies
The so-called "silver spoon" effect -- in which wealth is passed down from one generation to another -- is well established in some of the world's most ancient economies.
Poor in rural Oregon face 'double binds' when getting food
A new study by Oregon State University researchers shows that those in poverty in rural Oregon often know what kinds of foods they should be eating, but face tough choices between eating well and spending less money for meals.
Ethiopia 27 million years ago had higher rainfall, warmer soil
Thirty million years ago, before Ethiopia's mountainous highlands split and the Great Rift Valley formed, the tropical zone had warmer soil temperatures, higher rainfall and different atmospheric circulation patterns than it does today, according to new research of fossil soils found in the central African nation.
Early hominid first walked on two legs in the woods
Among the many surprises associated with the discovery of the oldest known, nearly complete skeleton of a hominid is the finding that this species took its first steps toward bipedalism not on the open, grassy savanna, as generations of scientists - going back to Charles Darwin - hypothesized, but in a wooded landscape.
High mortality rates may explain small body size
A new study suggests that high mortality rates in small-bodied people, commonly known as pygmies, may be part of the reason for their small stature.
Kent State University Professor C. Owen Lovejoy helps unveil oldest hominid skeleton
Throw out all those posters and books that depict an ape evolving into a human being, says Kent State University Professor of Anthropology Dr. C. Owen Lovejoy.
Studies examine how living conditions impact reproductive health
When costs outweigh benefits, successful pregnancies are less likely to occur. Life is all about tradeoffs and recently published research by Virginia J. Vitzthum, a senior scientist at Indiana University's Kinsey Institute for Research in Sex, Gender, and Reproduction, and professor in the IU College of Arts and Sciences' Department of Anthropology, has shown that during periods of intense labor and low food intake, rates of early pregnancy loss can more than double.
