Radiocarbon dating of the iceman otzi with accelerator mass spectrometry
A result of the Iceman's poor dental care (see below), this DNA came from the bacteria related to his periodontal disease.It traveled through his blood stream and colonized on his hip bone, which a biopsy revealed.That, in turn, caused Ötzi to go into shock and suffer a heart attack, according to the article published online in the .Even today, the chances of surviving such an injury long enough to receive hospital treatment are only 40 percent...." Chief researcher Frank Rühli said that the Ct images show "a large hematoma, which means he must have had huge bleeding into the thorax cavity." His death, the scientists stated, would have been rather quick under these circumstances.Because this agent is usually "absorbed shortly after an injury occurs," they concluded that the Iceman must have died quickly or the agent would not still be present.analyzed the Iceman's tattoos--all 61 of them (they found two more during their analysis).A reanalysis of Ötzi's findspot, along with the distribution of the artifacts located there, has prompted archaeologist Alessandro Vanzetti (Sapienza University of Rome), Luca Bondioli (National Museum of Prehistory and Ethnography in Rome) and three other scientists to conclude that the Iceman was killed at a lower altitude, carried up the mountain, and placed on a burial platform of stones.
The authors concluded that the "presence of the tattoos and their precise positioning on the mummy's body shall prove helpful in the future for the in-depth analysis of their relationship with recent scientifically acquired knowledge, to help determine the real function of tattooing in prehistoric times." An interesting study published in PLo S ONE found a sizable amount of non-human DNA in Ötzi's body.
They found 19 men who shared this same anomaly, which is a "reliable marker for ancestral relationships." There will probably be other living relatives to Ötzi, especially when a larger sample of men is studied.
, found that the Iceman had a number of cavities, severe wear on his tooth enamel from eating grain that was not finely ground, and periodontal disease.
By the way, MALDI-TOF is short for "Matrix-assisted laser desorption/ionization time-of-flight." Swiss researchers have used a multi-slice CT-scan at the University of Zurich to piece together views of the iceman's shoulder and determine exactly how he died.
They established that the point of the arrow tore "a hole in an artery beneath his left collarbone, leading to a massive loss of blood.
