Since 1991, when the 5,300-year-old mummy commonly known as Ötzi was discovered atop a mountain in the Italian Alps, researchers have studied
every inch of his
remarkably preserved remains. Scientists have uncovered hints as to what he ate, how he lived,
diseases he suffered from and even how he died.
While Ötzi's frozen body has provided a wealth of knowledge about the lives of ancient Europeans, there are still many limits to what researchers can learn about him. Of particular interest is the species of animals that lent their hides for Ötzi to wear. After being frozen in ice for millennia, the hair and leather samples are too damaged for archaeologists to analyze with standard DNA techniques.
But using new analysis methods, scientists have unlocked a trove of information from the Copper Age man. They describe their results in a study published today in the journal
Scientific Reports."Just based on the hair or just based on the type of leather, it's not easy sometimes to come down to the species level," microbiologist
Frank Maixner, one of the study's authors, tells Smithsonian.com. "It was clear to have a little bit more insight, we had to go for the DNA."
In order to learn more about Ötzi's fashion choices, Maixner and his colleagues at the European Academy of Bozen/Bolzano (EURAC) used a form of DNA analysis that relies on markers found in mitochondrial DNA. While most DNA is stored in chromosomes within cells, mitochondria contain a tiny piece of their own DNA. It's a small fraction of the total human genome, but for the scientists, it was enough to pinpoint several animals that Ötzi turned into specific pieces of clothes.
