60秒科学:King Tut's Tough Life

King Tut's Tough Life
New analysis of the mummy of King Tut, published in the Journal of the American Medical Association, shows that the boy king had severe bone disease and malaria¹. Christopher Intagliata reports

The Journal of the American Medical Association doesn’t usually report autopsy² results. But they make an exception this week: for King Tut. The study of the boy king involved DNA³ analysis and CAT scans.

Researchers [led by Zahi Hawass of the Supreme⁴ Council of Antiquities⁵ in Cairo, Egypt] used genetic⁶ fingerprints⁷ from Tut and 10 presumed relatives to map out his most accurate five-generation family tree to date. It reveals a family history of clubfoot and scoliosis. And CAT scans of Tut turned up foot deformities, like a missing toe bone, and bone necrosis, which means some of his foot bones were dying due to poor blood circulation. Previous scans had identified a femur fracture.

The tests also found DNA from Plasmodium falciparum, meaning that the teenager and his great-grandparents had malaria infections. It's the oldest genetic proof for malaria in well-dated mummies. DNA also shows that Tut was probably spared bubonic plague, tuberculosis⁸, leprosy or leishmaniasis.

So here's the scenario⁹ the researchers propose: an already frail¹⁰ pharaoh, hobbling around on his cane¹¹, breaks his leg, maybe in a fall. Throw in that malaria infection, and around 1324 B.C., just nine years after taking the throne, King Tut was history.
