Ancient Egyptian genome reveals Mesopotamian ancestry and hints of cross-cultural exchange

Scientists have sequenced the full genome of a man buried in pharaonic Egypt over 4,500 years ago, revealing that about 20% of his ancestry came from Mesopotamia, in a rare discovery linking the two early civilisations.

The man’s remains were excavated in 1902 from a rock-cut tomb near Beni Hassan, around 270km south of Cairo. His skeleton was found sealed inside a ceramic vessel, which researchers say helped preserve his DNA despite Egypt’s harsh climate.

The individual lived between 4,500 and 4,800 years ago during Egypt’s Old Kingdom period, the era marked by the construction of the earliest pyramids. At death, he was about 60 years old and showed signs of age-related ailments, including osteoporosis, osteoarthritis, and a severe tooth infection.

Researchers sequenced his entire genome using DNA extracted from the roots of two teeth — a first for ancient Egyptian remains. They found that 80% of his ancestry was linked to local populations in Egypt and North Africa, while 20% came from the eastern Fertile Crescent, a region that included Mesopotamia, now part of modern-day Iraq, Iran and Syria.

“This suggests substantial genetic connections between ancient Egypt and the eastern Fertile Crescent,” said Adeline Morez Jacobs, a population geneticist at Liverpool John Moores University and the Francis Crick Institute, and lead author of the study published in Nature.

The findings lend genetic weight to existing archaeological evidence of trade and cultural links between Egypt and Mesopotamia. During the third millennium BC, both regions were centres of early civilisation, sharing technologies, artistic motifs, and trade in goods such as lapis lazuli.

Pontus Skoglund, a co-author from the Francis Crick Institute, said the man’s DNA was exceptionally well preserved thanks to the ceramic vessel and rock-cut tomb. “Ancient DNA recovery from Egyptian remains has been exceptionally challenging due to the climate,” he said.

Bioarchaeologist Joel Irish added that while the man’s skeletal features suggest he may have been a potter — a physically demanding trade — his burial in a rock-cut tomb indicated high social status. “Perhaps he was an excellent potter,” Irish said.

Previous attempts to extract DNA from ancient Egyptian remains have largely failed or yielded only partial sequences, making this case a notable exception and a breakthrough for the field of paleogenetics.
