Otzi's remains were discovered in a glacier in the Ötzal Italian Alps in 1991, and since then scientists have spent decades researching his ancestry, diet, tools, lifestyle, health and attire.
While biomolecular research on Otzi's clothing has been hampered by the material's relatively high decomposition, in the latest study scientists used new techniques of mitochondrial DNA capture and gene sequencing to analyze the materials.
In their article, published in the journal Scientific Reports, the scientists said that the genome sequencing shows the animals' genetic relation to those found in the Tyrolean region today.
"The genetic haplotypes of the wild species of both roe deer and brown bear are consistent with present day phylogeography (geographical genetic distribution) in the Alpine region."
Scientists have also studied the remains of Otzi's stomach and found 30 different types of pollen, leading them to deduce that he died in spring or early summer. In July 2001 they X-rayed Otzi's skeleton and discovered a flint arrowhead in his shoulder, which is probably what killed him.
