Researchers in the US have used DNA data from mummified remains to create 3D reconstructions of the faces of three men who lived in ancient Egypt more than 2,000 years ago.
The mummies came from Abusir el-Meleq, an ancient Egyptian city to the south of Cairo, and they were buried between 1380 B.C. and A.D. 425, LiveScience reported.
In 2017, researchers at the Max Planck Institute for the Science of Human History in Tübingen, Germany have successfully sequenced the DNA from Egyptian mummies for the first time.
Taking on the technology, researchers at Parabon NanoLabs, a DNA technology company in Reston, Virginia, have used that genetic data to create 3D models of the mummies’ faces.
The experts created the faces through a process called forensic DNA phenotyping which uses genetic analysis to be recreate the shape of facial features and other aspects of a person’s physical appearance.
“This is the first-time comprehensive DNA phenotyping has been performed on human DNA of this age,” Parabon representatives said in a statement.
Parabon revealed the mummies’ faces on Sept. 15 at the 32nd International Symposium on Human Identification in Orlando, Florida.
Scientists used a phenotyping method called Snapshot to predict the men’s ancestry, skin color and facial features.
The findings reveal that these ancient people were more genetically like populations living in the eastern Mediterranean — a region that today includes Syria, Lebanon, Israel, Jordan and Iraq — than people living in modern-day Egypt. The researchers then generated 3D meshes outlining the mummies’ facial features, and calculated heat maps to highlight the differences between the three individuals and refine the details of each face.
Parabon’s forensic artist then combined these results with Snapshot’s predictions about skin, eye, and hair color.
Worldwide, the remains of thousands of mummies from ancient Egypt have been excavated, but obtaining intact, undamaged DNA from the bodies has proved challenging.
Other research teams made at least previous attempts to sequence DNA from mummies but proved inconclusive. The first undertaking occurred in 1985 and was later shown to be flawed, because the samples had become contaminated with modern DNA.
However, the new processes used on these ancient mummies could also help scientists to recreate faces to identify modern remains, Ellen Greytak, Parabon’s director of bioinformatics, told Live Science. Of the approximately 175 cold cases that Parabon researchers have helped to solve using genetic genealogy, so far nine were analyzed using the techniques from this study, Greytak said.
