“We are testing the limits… and seeing how far back in time we can go,” said Gowland, who was not involved in this latest study. It’s exploding a little bit, which is exciting,” said bioarchaeologist Rebecca Gowland, a professor at the University of Durham, who was part of a team that first developed the method involving tooth enamel. Amelogenin, however, preserves well, meaning it could be widely used to figure out the sex of even incomplete skeletons. Research Group ATLAS from University of SevillaĪncient DNA can also reveal the sex of human remains, but it’s fragile, easily contaminated, expensive and often not possible to retrieve from damaged bones, particularly in warmer places. That’s why it’s easy to make mistakes when looking at a pelvic opening to determine biological sex, as in the case of the “Ivory Lady.”Īn elephant's tusk found in the grave indicated the woman may have traveled to faraway places. The problem is that hip bones - compared with some other parts, such as skulls - are thin, which means they turn brittle over time and are easily crushed. The typical way archaeologists tell the sex of a skeleton is by looking at the pelvis: Women’s pelvises generally have wider openings than men’s do. In other studies, the technique has also been used to dispel the cliché of “man the hunter” that has informed much thinking about early humans. The newer method to determine the sex of old bones - first used in 2017 - involves analyzing tooth enamel, which contains a type of protein with a sex-specific peptide called amelogenin that can be identified in a lab.Īnalysis of a molar and an incisor from the skeleton detected the presence of the AMELX gene - which produces amelogenin and is located on the X chromosome - indicating that the remains were female rather than male, according to the study.

The woman's tomb was filled with lavish grave goods. “This technique, we think, is going to open up an entirely new era in the analysis of the social organization of prehistoric societies.” Therefore, he’s a man.’ Of course, deeply mistaken, because it assumes that in the past gender roles were the way we conceive them today,” García Sanjuán said. “In the past, it was not uncommon for an archaeologist to find (remains) and say, ‘OK, this individual has a sword and a shield. What they learned about the woman and the society she lived in opens a new window on the past and will likely force many to reconsider traditionally held views about prehistory. So, this actually forced us to rethink everything about this site,” said study author Leonardo García Sanjuán, a professor of prehistory at the University of Seville. It turned out that the “Ivory Man” was in fact a woman. More than a decade later, the researchers used a new molecular method in 2021 to confirm the skeleton’s sex as part of a broader study on the discovery, and they got quite a shock. A team of European archaeologists dubbed the remains the “Ivory Man,” and began researching what they called a “spectacular” find. Buried with an elephant’s tusk, an ivory comb, a crystal dagger, an ostrich eggshell and a flint dagger inlaid with amber, the skeleton discovered in a tomb near Seville, Spain, in 2008 was clearly once someone important.īased on analysis of the pelvis bone, a specialist initially identified the 5,000-year-old skeleton as a “probable young male” who died between age 17 and 25.
