What explains the disappearance of Haplogroup C1a2 in Europe

[Illyrius]

So i saw this ancient paleolithic human skulls thread and it got me wondering about something.
What exactly caused this once major haplogroup's extinction in Europe. Why did it thrive in central and east asia but perished in the west?
Does anyone have any theories or conclusions about it?

I'm really curious right now I'd love to learn more about this odd haplogroup.

Mixing. It was mixed out of existence or they all died.

Due to their lifestyle native Hunter-Gatheres were a very small population in comparison to Farmers who could sustain a much larger population and also ANE Indo-Europeans who herded animals.

Kinda how Native Americans are almost completely dissapeared today, the scenario may have been very similar.

I see i see..i get the picture now. Everything is coming together and makes sense

But again we don't know how sparse exactly it is, with the current amount testing that has been done a very tiny percentage of Europeans still do carry C1.

But referring back to this post:

Its still very debatable which haplogroup is actually most dominant both Ydna and Mtdna.

The percentages of haplogroups for most countries are calculated from very little people actually tested. For example the entire Ydna and Mtdna statistic of Bulgaria is derived from 1000 people. 1000 people of 8 million. The ratio for the other countries is usually similar.

So nobody knows what the Ydna and Mtdna map of Europe would actually look like if every person was tested.

If higher percentages of people get tested in may turn out C1 is nowhere near as disappeared as we think it is. Might actually be out there in decent quantities.

Mixing with I, then overpopulating by G, and then R-made cleansing.

What did C1 people look like??

C-V20 is not extinct it still shows up in 1 in every few thousand Europeans

A way you can look at this is that in a database of 197,362 modern men 47 showed up as belonging to C-V20 So that's about 1 in 4,200

However not all of the 197,362 modern men list a place in Europe as where their earliest known paternal ancestors came from nor did 3 of the 47 men.

Looking at all the other info I can find it seems the frequency of C-V20 in Europe is probably between 1 in every 1500-4500 modern Europeans

Probably something like aboriginals and veddoids.

Probably something like aboriginals and veddoids.

you think this is how WHG looked ? (but with blue eyes)

+/-. Rosbust body, squere face, black skin (and eyes!), caucasoid features.
Look at Melanesians or dark Polinesians. They look often very caucasian, similarly like Veddoids and Dravidians, but are big, robust.
I and C folk were something similar, but original C folk was probably more australolid, like C-brothers in Asia.

Original WHG has no blue eyes. Blue eyes appeard at the very end of their separate existance and with EHG (i.e. indoeuropean) admix.
