Sardinians are among the most genetically distinctive modern European populations, carrying unusually high proportions of Neolithic Anatolian farmer ancestry and correspondingly low proportions of later steppe ancestry (which has transformed most of continental Europe’s genetics).

The Sardinian genetic profile represents, in some ways, a window into what pre-steppe European genetics looked like.

Ötzi’s genome extended that window backward into the Copper Age, confirming that the Alpine populations of the fourth millennium BCE were similarly “preserved” in their genetic character relative to the broader transformations of European population history.

The Appearance That Rewrote The Image

The finding about ancestry was important but technical — the kind of result that matters greatly to ancient genomics researchers and to the broader scientific community, but that doesn’t immediately shift the popular understanding of who Ötzi was.

The findings about Ötzi’s physical appearance were different.
