Article: Human Ancestors Traced to 1 Small Group; DNA Study Suggests Current Species Originated Just 270,000 Years Ago

Scientists who tested the Y chromosomes of 38 men all over the world have found evidence suggesting that everyone living today descended from one small population of a few thousand people who may have lived about 270,000 years ago. The researchers say those ancient people may have been the first representatives of the modern human species.
