Science quotes, from a lecture given at the 7th World Congress on Mummy Studies, the latest findings concerning Europe’s oldest natural human mummy, found in September 1991 in the Ã–tztal Alps, near Hauslabjoch on the border between Austria and Italy and usually referred to as Ã–tzi or the Iceman.
Less than 2 hours before he hiked his last steps in the Tyrolean Alps 5000 years ago, Ã–tzi the Iceman fueled up on a last meal of ibex meat. That was the conclusion of a talk here last week at the 7th World Congress on Mummy Studies, during which researchersâ€”armed with Ã–tzi’s newly sequenced genome and a detailed dental analysisâ€”also concluded that the Iceman had brown eyes and probably wasn’t much of a tooth brusher.
The Iceman, discovered in the Italian Alps in 1991 some 5200 years after his death, has been a gold mine of information about Neolithic life, as researchers have extensively studied his gearâ€”copper ax, hide and leather clothing, and accessoriesâ€”and his body. Previous research on the Iceman’s meals focused on fecal material removed from his bowels. The contents showed that he dined on red deer meat and possibly cereal some 4 hours before his death.
But a team led by microbiologist Frank Maixner of the Institute for Mummies and the Iceman in Bolzano, Italy, recently reexamined computed tomography scans taken in 2005 and spotted, for the first time, the Iceman’s stomach. As the researchers reported at the meeting, the organ had moved upward to an unusual position, and it looked full. When they took a sample of the stomach contents and sequenced the DNA of the animal fibers they found, they discovered that Ã–tzi, just 30 to 120 minutes before his death, had dined on the meat of an Alpine ibex, an animal that frequents high elevations and whose body parts were once thought to possess medicinal qualities.
The new findings are “cutting edge” says Niels Lynnerup, a specialist in forensic medicine at the University of Copenhagen. “We are now inching our way to the last minutes of the Iceman.”
In a separate presentation, dentist Roger Seiler and anatomist Frank RÃ¼hli of the Centre for Evolutionary Medicine at the University of ZÃ¼rich, examined the dental health of the Iceman, who probably died between the age of 35 and 40. Previously, researchers examining radiological images of his teeth discerned no trace of cavities or other dental problems. But the Swiss team created new three-dimensional images of the ancient traveler’s dentition. These showed that the Iceman suffered a blunt force trauma to two teethâ€”possibly a blow to the mouthâ€”at least several days before his death and was plagued by both periodontal disease and cavities. The cavities, Seiler said in his talk, confirm that the Iceman ate a diet abounding in carbohydrates, such as bread or cereal, and reveal that he possessed a “heavy bacterial dose on these teeth.”
