The oldest known Egyptian DNA sample, from a man who lived between 4,500 to 4,800 years ago, offers new insights into the potential ancestry of those who belonged to the enduring civilization.

DNA obtained from the remains of a man who lived in ancient Egypt around the time the first pyramids were built is providing evidence of the ties between two great cultures of the period, with a fifth of his genetic ancestry traced to Mesopotamia.

Ancient DNA has revealed a genetic link between the cultures of ancient Egypt and Mesopotamia, according to research published Wednesday in the journal Nature. Researchers sequenced whole genomes from the teeth of a remarkably well-preserved skeleton found in a sealed funeral pot in an Egyptian tomb site dating to between 4,
