The Iceman’s maternal genetic line originated in the Alps and is now extinct.
A study was published last week on the DNA of Helicobacter pylori, the pathogen extracted from the stomach of Ötzi, the ice mummy who has provided valuable information on the life of Homo Sapiens; new research at the European Academy of Bolzano/Bozen (EURAC) further clarifies the genetic history of man who lived in the Eastern Alps over 5,300 years ago. In 2012 a complete analysis of the Y chromosome (transmitted from fathers to their sons) showed that Ötzi’s paternal genetic line is still present in modern-day populations. In contrast, studies of mitochondrial DNA (transmitted solely via the mother to her offspring) left many questions still open. To clarify whether the genetic maternal line of the Iceman, who lived in the eastern Alps over 5,300 years ago, has left its mark in current populations, researchers at the European Academy of Bolzano/Bozen (EURAC) have now compared his mitochondrial DNA with 1,077 modern samples.
