Oetzi the Iceman has a new look. Decades after the famous glacier mummy was discovered in the Italian Alps, scientists have dug back into his DNA to paint a better picture of the ancient hunter.
They determined that Oetzi was mostly descended from farmers from present day Turkey, and his head was balder and skin darker than what was initially thought, according to a study published Wednesday in the journal Cell Genomics.
Oetzi, who lived more than 5,000 years ago, was frozen into the ice after he was killed by an arrow to the back. His corpse was preserved as a “natural mummy” until 1991, when hikers found him along with some of his clothing and gear — including a copper ax, a longbow and a bearskin hat. Since then, many researchers have worked to uncover more about the mummy, which is displayed at the South Tyrol Museum of Archaeology in Bolzano, Italy.
An earlier draft of Oetzi’s genome was published in 2012. But ancient DNA research has advanced since then, so scientists decided to take another look at the iceman’s genes, explained study author Johannes Krause, a geneticist at Germany’s Max Planck Institute for Evolutionary Anthropology. They used DNA extracted from the mummy's hip bone.
The updated genome is “providing deeper insights into the history of this mummy,” said Andreas Keller of Germany’s Saarland University. Keller worked on the earlier version but was not involved with the latest study.
Based on the new genome, Oetzi's appearance when he died around age 45 was much like the mummy looks today: It's dark and doesn't have much hair on it, said study author Albert Zink, head of the Institute for Mummy Studies at Eurac Research in Italy. Scientists previously thought the iceman was lighter-skinned and hairier in life, but that his mummified corpse had changed over time.
His genome also showed an increased chance of obesity and diabetes, the researchers reported.
And his ancestry suggests that he lived among an isolated population in the Alps, Zink said. Most Europeans today have a mix of genes from three groups: farmers from Anatolia, hunter-gatherers from the west and herders from the east. But 92% of Oetzi’s ancestry was from just the Anatolian farmers, without much mixing from the other groups.

After the latest school shooting in Uvalde, Texas, it wouldn't be a surprise if the traumatic event takes a toll on your mental health — or that of your children. Amy Morin, the editor-in-chief of Verywell Mind and licensed psychotherapist, joined Cheddar News to share coping skills and offer advice about how to talk to your children about these increasingly common tragic events. “I think its important for parents to know what the school’s plan is, what the teacher's plan is, and then we can have our own plans with kids too," she noted. "It's so important for us to talk to kids about how they're feeling — guaranteed they've heard something about it, so ask them what they know already, use age-appropriate language, and rather than just dismissing their fears by saying don't worry about it or I'm sure you'll be safe, talk to them about their feelings."
An recently conducted AP-NORC poll found that majorities of the Black and Hispanic populations in the U.S. still find themselves either somewhat worried or extremely worried over the pandemic, while more than half of white Americans responded with either being not too worried or not worried at all. Dr. Chris Pernell, the chief strategic integration and health equity officer at University Hospital, joined Cheddar News to talk about how perceptions of COVID-19 differ between groups of Americans. "We’re still seeing people get infected, and because of the toll of the disproportionate impact, we have concerns among the Black and brown community about whether or not they have an increased risk of exposure because of where they work, because of the use of public transportation, because they live in homes that they may not be able to safely quarantine and or isolate in, and because they have at baseline chronic health conditions that may make coronavirus more severe in those persons," she said.
Judith Enck, a former regional administrator for the EPA and the president of Beyond Plastics, joined Cheddar News to talk about the role of plastics in the climate crisis and California's investigation of ExxonMobil and other oil companies for misleading the public on the ability to recycle plastics. "The reason why petrochemical companies like Exxon have gotten away with selling more and more plastic is that they've lied to the public and told us don't worry about all those negative upstream impacts and downstream impacts of plastics. Just be sure to recycle it. Well, guess what? Plastics largely are not recycled," Enck said.

Virtual care and digital medicine provider Biofourmis recently raised $300 million in a Series D round led by General Atlantic and with participation from CVS Health. Biofourmis offers at-home care and digital therapies backed by artificial intelligence, which can remotely monitor patients while they are at home. The company says it hopes its technology can improve patient outcomes while reducing the cost and burden of care. Kuldeep Signh Rajput, Founder and CEO of Biofourmis, joins Cheddar News' Closing Bell to discuss.
Moderna is asking the FDA to consider emergency use authorization for its COVID vaccine to be used with children under 6 years old. Dr. Christina Johns, a senior medical advisor at PM Pediatrics, joined Cheddar News to talk about the pharmaceutical company's research into the safety and efficacy of the vaccine for the very youngest of children. "This is very exciting news because children met that goal in their neutralizing antibody response in this age group — means that we really can extrapolate a lot from what we know about data in adults," she said. "I will say that there's a caveat that we have not seen yet the full dataset released, so I'm waiting for that and my fingers are crossed for next week."
