The finding addresses the ongoing debate over when and how many times the ancestors of present-day Native Americans entered the New World from Siberia. Archaeological evidence logs modern humans in the Americas 15,000 years ago. Continue reading

An 8,500-year-old male skeleton discovered in 1996 in Washington State sparked bitter disputes between Native Americans, American scientists, and within the American scientific community. Earlier studies suggested he was not ancestral to Native Americans, blocking repatriation. Now his genome sequence shows Kennewick Man is more closely related to modern Native Americans than to any other population worldwide. Continue reading
Three new independent studies found that another part of the equation is a woman’s desire to maintain her body’s attractiveness, says social psychologist and assistant professor Andrea L. Meltzer, Southern Methodist University, Dallas. Continue reading
Uplift associated with East Africa’s Great Rift Valley and the environmental changes it produced have puzzled scientists for decades because the timing and starting elevation have been poorly constrained.
Now paleontologists have tapped a fossil from the most precisely dated beaked whale in the world — and the only stranded whale ever found so far inland on the African continent — to pinpoint a date when the mysterious elevation began. Continue reading
SMU analysis of recent North Texas earthquake sequence reveals geologic fault, epicenters in Irving and West Dallas
Initial results from the seismology team at Southern Methodist University reveal that a recent series of earthquakes near old Texas Stadium in the Dallas-Fort Worth area were relatively shallow and concentrated along a narrow two-mile line that indicates a fault extending from Irving into West Dallas. SMU and the United States Geological Survey have shared an interim report with the mayors of Dallas and Irving. Continue reading
Scientists issue call to action for archaeological sites threatened by rising seas, urban development
Should global warming cause sea levels to rise as predicted in coming decades, thousands of archaeological sites in coastal areas around the world will be lost to erosion.
With no hope of saving all these sites, an SMU archaeologist and others call for scientists to assess the sites most at risk.
