WASHINGTON -- Ancient DNA has revealed a genetic link between the cultures of ancient Egypt and Mesopotamia, according to research published Wednesday in the journal Nature.

Forty years after the first effort to extract mummy DNA, researchers have finally generated a full genome sequence from an ancient Egyptian, who lived when the earliest pyramids were built

But while experts now know a fair amount about ancient Egyptian life, they still understand very little about the population’s genetic makeup. Researchers have genomically analyzed three specimens to date,
