Anthropologist Henry C. Harpending and his colleagues believe that humans are evolving more rapidly than in the distant past. Their genetic analysis suggests people are evolving more rapidly than in the distant past, with residents of various continents becoming increasingly different from one another.

"Rapid population growth has been coupled with vast changes in cultures and ecology, creating new opportunities for adaptation," the study says. "The past 10,000 years have seen rapid skeletal and dental evolution in human populations, as well as the appearance of many new genetic responses to diet and disease."
