I would love to try this on some of my ancestors’ DNA! Imagine the thrill of seeing their faces.
OK, so collecting DNA samples might be “unpleasant” at this late date but I still think the end results would be a thrill

TORONTO — DNA researchers have given us a glimpse of what Ancient Egyptians may have looked like. Researchers from Parabon NanoLabs, a Virginia-based DNA technology company, have created 3D reconstructions of the faces of three men after processing DNA samples from mummies.
The mummified men — named JK2134, JK2888 and JK2911 — are estimated to be between 2,000 and 2,800- years-old. They come from Abusir el-Meleq, an ancient Nile River community in Egypt. JK2134 is thought to date back from 776 to 569 BC and JK2888 is estimated to be from 97 to 2 BC, while JK2911 is from approximately 769 to 560 BC.
The researchers shared their findings at the 32nd International Symposium on Human Identification earlier this month.
Using a process called DNA phenotyping, they were able to extract genetic information about the men’s physical characteristics and ancestry to generate 3D models of what they may have looked like when they were around 25 years of age.
The researchers found that the three men were primarily of Middle Eastern ancestry, with some Southern European ancestry mixed in. Their ancestry turned out to be more similar to modern Mediterranean and Middle Eastern people rather than present-day Egyptians.
Because the DNA samples were so old, some key genetic information was missing or damaged, so the researchers had to make a few predictions to fill in the gaps. The samples were missing the genetic information associated with eye colour and hair colour, so researchers applied dark brown hair and eyes — the most common hair and eye colors in the Middle Eastern population.
Much of the genetic information for skin colour was also missing, so the researchers similarly predicted that the men had light brown complexions.
“It’s great to see how genome sequencing and advanced bioinformatics can be applied to ancient DNA samples,” said Ellen Greytak, Parabon’s bioinformatics director, said in a news release.
Many police departments around the world use this technology to generate reconstructions when unidentified remains are found. Parabon researchers say it’s the first time that such DNA analysis has been done on specimens that are this old.
