I1565 + OST003 23andme format

When we think about Neolithic Europe, we usually imagine a continent transformed by incoming farmers from Anatolia, agriculture spreading, villages forming, and hunter-gatherers gradually disappearing into the genetic background. But the DNA doesn’t always follow the neat story we expect. Today, we’re looking at two remarkable Neolithic individuals from Germany who challenge the idea that Europe’s indigenous hunter-gatherers were quickly absorbed or replaced.

The first is OST003, from northeastern Germany, dated to around 3200 BCE, carrying the Y-chromosome lineage I1, known to be common in modern Scandinavians. The second, I1565, comes from western Germany and dates even earlier, to about 3700 BCE, with a Y-chromosome lineage I2a. What makes both of these individuals extraordinary is their ancestry. This qpAdm analysis on I1565 reveals it is under 10 percent Anatolian, with the rest being Western Hunter-Gatherer.

This qpAdm run on OST003 reveals that it is 85 percent Western Hunter-Gatherer with only 14 percent Anatolian-related ancestry.

F4 runs on both OST003 and I1565 show basically the same picture - they are Anatolian shifted relative to European hunter-gatherers, and significantly hunter-gatherer shifted relative to Anatolians.
