The ancient tribes which made us rh negative

As we are looking into the ancestries responsible for us being rh negative, we can easily take a quick look into where rh negative frequencies have once been high.

If we compute expected phenotypic frequencies, this suggests that around around 65% of Mesolithic hunter-gatherers would have been type O, compared to around 40% in present-day Europeans, and around 40% of Steppe-ancestry individuals would have been Rh-, compared to around 24% of hunter-gatherers, 4% of early farmers, and about 16% of present-day Europeans.

The Caucasus is an interesting connection point where several ancient cultures came together.

The early farmers came from the region of Anatolia, now Turkey. And those groups were low in rh negative blood. So we are a mix of different tribes, some high in rh negative frequencies, others lower.
