DNA
from mummies found at a site once known for its cult to the Egyptian god of the
afterlife is unwrapping intriguing insight into the people of ancient Egypt,
including a surprise discovery that they had scant genetic ties to sub-Saharan
Africa.
Scientists
on Tuesday said they examined genome data from 90 mummies from the Abusir
el-Malek archaeological site, located about 115 km south of Cairo, in the most
sophisticated genetic study of ancient Egyptians ever conducted.
The
DNA was extracted from the teeth and bones of mummies from a vast burial ground
associated with the green-skinned god Osiris. The oldest were from about 1388
BC during the New Kingdom, a high point in ancient Egyptian influence and
culture. The most recent were from about 426 AD, centuries after Egypt had
become a Roman Empire province.
“There
has been much discussion about the genetic ancestry of ancient Egyptians,” said
archeogeneticist Johannes Krause of the Max Planck Institute for the Science of
Human History in Germany, who led the study published in the journal Nature
Communications.
“Are
modern Egyptians direct descendants of ancient Egyptians? Was there genetic
continuity in Egypt through time? Did foreign invaders change the genetic
makeup: for example, did Egyptians become more ‘European’ after Alexander the
Great conquered Egypt?” Krause added. “Ancient DNA can address those
questions.”
The
genomes showed that, unlike modern Egyptians, ancient Egyptians had little to
no genetic kinship with sub-Saharan populations, some of which like ancient
Ethiopia were known to have had significant interactions with Egypt.
The
closest genetic ties were to the peoples of the ancient Near East, spanning
parts of Iraq and Turkey as well as Israel, Jordan, Syria and Lebanon.
Egypt,
located in North Africa at a crossroads of continents in the ancient
Mediterranean world, for millennia boasted one of the most advanced
civilizations in antiquity, known for military might, wondrous architecture
including massive pyramids and imposing temples, art, hieroglyphs and a
pantheon of deities.
Mummification
was used to preserve the bodies of the dead for the afterlife. The mummies in
the study were of middle-class people, not royalty.The researchers found
genetic continuity spanning the New Kingdom and Roman times, with the amount of
sub-Saharan ancestry increasing substantially about 700 years ago, for unclear
reasons.
“There
was no detectable change for those 1,800 years of Egyptian history,” Krause
said. “The big change happened between then and now.”
