The calm before the storm


It's been another slow month in the world of ancient DNA. I can promise you that next month is going to be awesome. Meantime, here's some reading to keep you awake until the dry spell breaks. Please note, some of these aren't meant to be taken seriously.

That Gresky et al. paper is stuck behind a pay wall, but there are lots of details about the samples in the free supp info...

Any news on the Xiahoe/Tarim Mummies aDNA?.

Davidski said...

I haven't heard anything.

Going to be Z-280's aren't they ? ;)

Davidski said...

There will be some Z282 in ancient South Central Asian remains, if enough of them are sampled. But I think the Tarim Basin R1a will belong to a sister clade of Z282 and Z93 that is now very rare, and only occasionally found in Tibet, Central Asia and West Asia.

Nirjhar007 said...

What makes you so sure?, do you have info that they tested for Z-280's also? and which rare clade you are talking about here?.

Davidski said...

I'm just speculating. It might end up being Y17491, which is actually under Z282.

In any case, you can forget about Z280 being there. It looks like a marker that colonized Eastern Europe recently from the west.

Nirjhar007 said...

My first bet is it will be Z-282 or related.

Second is L-664 and Third is a rare or extinct branch of M-417, in any case I have no problems whatsoever .

In case of Afanasievo , going against the majority of prediction, I think it will be mostly R1a-M417+ .

So lets see how it goes :) .

' It (Z280) looks like a marker that colonized Eastern Europe recently from the west.'

As in sometime in the mid-late Bronze Age ?

Davidski said...

Z280 was probably common in much of what is generally thought of as Eastern Europe since the Corded Ware, especially in the proto and early Baltic areas. But I don't think it became as common as it is now in southern and eastern European Russia until after the Srubnaya people cleared out into Asia.
