KENYA SKELETONS MAY SHOW EARLIEST EVIDENCE OF HUMAN WARFARE -- DATING TO ABOUT 10,000 YEARS AGO

Skeletons unearthed in Kenya may be the oldest known evidence of human warfare, according to a new study.

The skeletons of 27 people who died about 10,000 years ago bear marks of blunt force trauma and projectile wounds, the researchers said in the study. The victims included men, women and children.

"That scale of death — it can't be an individual murder or homicide amongst families," said study co-author Robert Foley, an anthropologist and archaeologist at the University of Cambridge in England. "It was a result of some intergroup conflict."
