It places him at the extreme end of the distribution, with more farmer ancestry than most contemporaneous Europeans.

The most likely explanation, as noted earlier, is geographic isolation.

The Alpine communities of the Copper Age, enclosed by difficult mountain terrain, mixed less with the wider European population than communities in more accessible regions.

Over generations, this limited mixing maintained a higher proportion of Anatolian farmer ancestry than the surrounding lowland populations had.

This interpretation has implications for understanding the role of geographic barriers in shaping genetic diversity.

The Alps apparently served as a significant genetic barrier even in the Copper Age, when human mobility was limited to foot and animal transport but trading connections and seasonal movement existed across the passes.
