In 1991, German tourists discovered, in the Eastern Italian Alps, a human body that was later determined to be the oldest naturally preserved ice mummy, known as Otzi or the Iceman. Now, researchers reporting in the journal Current Biology on July 12 who have conducted the first in-depth analysis of the Iceman’s stomach contents offer a rare glimpse of our ancestor’s ancient dietary habits. Among other things, their findings show that the Iceman’s last meal was heavy on the fat.
