Inferring the linguistic affinity of long dead and non-literate peoples: a multidisciplinary approach

Ancient DNA has treated us to many surprises in recent years. But it has also uncannily corroborated some well established hypotheses that were formulated decades ago from historical linguistics and archeological data. One such hypothesis is that the population associated with the Late Neolithic Corded Ware culture (CWC), and its myriad offshoots, spoke early Indo-European languages and spread

Some myths die hard

Ancient DNA tells us that the Bronze Age wasn't kind to the indigenous populations of Central Asia. It seems to have wiped them out totally. Indeed, Central Asia might well be the only major world region in which native hunter-gatherers failed to make a perceptible impact on the genetics of any extant populations.

Before the Neolithic transition, much of Central Asia was home to hunter-gatherers

Map of pre-Corded Ware culture (>2900 BCE) instances of Y-haplogroup R1a

Below is a map showing the global distribution of Y-chromosome haplogroup R1a prior to the expansions of the R1a-rich Corded Ware culture (CWC) people and their descendants across Europe and Asia from around 2900 BCE. I'll be updating this map regularly and using it to help me narrow down the options for the place of origin of R1a, and also to counter the misinformation about this topic that has

On Maykop ancestry in Yamnaya

What Maykop ancestry in Yamnaya? There is none, or at least not enough worth discussing, except in one highly unusual female outlier from a burial in what is now eastern Ukraine. But apparently this is still up for debate? Well it shouldn't be.



To anyone with even a passing interest in the Yamnaya culture, it should be rather obvious that it formed during the tail end of the Eneolithic on the

A Bell Beaker superhighway

Below is a density heat map of Bell Beaker pottery finds from a recent paper titled Der Glockenbecher in Europa - eine Karteirung (The mapping of the Bell Beaker in Europe). It's freely available as part of a series of new archeological papers on the Bell Beaker phenomenon at the Journal of Neolithic Archeology (see here).



Particularly eye catching, at least for me, is the trail of high

The Boscombe Bowmen

I'm thinking that the Boscombe Bowmen site in Wiltshire, southern England, might be a valuable case study of how the Bell Beaker population, and thus also the present-day western European gene pool, came to be.

Dated to 2500–2140 BCE, this isn't an especially early Bell Beaker grave, but its inventory is intriguing. It includes seven All-Over-Cord (AOC) beakers and one Cord-Zoned-Maritime (CZM)

Dutch Beakers: like no other Beakers

In my last two blog posts I tried to explain why the so called Bell Beakers of prehistoric Europe cannot be confidently derived in any significant way from the Yamnaya population of the Carpathian Basin, and are more likely to have been an offshoot, in varying degrees, of the Single Grave or Corded Ware people of the Lower Rhine region (see here and here).

To help drive my message home, below is

Single Grave > Bell Beakers

I've been studying in detail the genetic substructures within the Bell Beaker population with formal statistics and Principal Component Analyses (PCA). As far as I can see, among the two most homogeneous, and thus least likely to be recently admixed, Beaker groups are the Dutch Beakers and also the Dutch and British Beaker males belonging to Y-haplogroup R1b-P312. This, of course, makes good

Hungarian Yamnaya > Bell Beakers?

Ever since the publication of the Olalde et al. Beaker paper (see here), there's been a lot of talk online about Hungarian Yamnaya as the most likely source of the Yamnaya-related, R1b-P312-rich northern Bell Beakers who went on to dominate much of Central and Western Europe during the Late Neolithic and Bronze Age.

Certainly, this is still possible, and we might find out soon if it's true

The resistance crumbles

Over the years some scientists from the Estonian Biocentre have been among the staunchest opponents of the idea that Bronze Age pastoralists originating in the steppes of Eastern Europe had a significant genetic and linguistic impact on South Asia (for instance, see here).

But this week they put out a review paper titled The genetic makings of South Asia [LINK] featuring the figure below. It's a

Corded Ware people =/= Proto-Uralics (Tambets et al. 2018)

A new paper on the genetic structure of Uralic-speaking populations has appeared at Genome Biology (see here). It looks to me like the prelude to a forthcoming paleogenetics paper on the same topic that was discussed in the Estonian media recently (see here). Although not exactly ground breaking (because it basically argues what I've been saying at this blog for years, like here and here), it's a

Indo-European crackpottery

I'm sometimes asked in the comments here and elsewhere what I think of Carlos Quiles and his Indo-European website (see here if you're game). Discussing this topic is a waste of time and effort, so I'm writing this blog post for future reference just in case this question comes up again. In all honesty, I think Carlos is a troll and his ramblings are of no value.



Now, many of you probably

A Mycenaean and an Iron Age Iranian walk into a bar...

What do they have in common? The same type of Near Eastern ancestry? From Iran? Nope, that's a joke. Obviously, they share the same type of steppe ancestry. This probably has some very important linguistic implications.



The relevant Principal Component Analysis (PCA) datasheet is available here. Below are two pairs of formal mixture models that support my inferences from the PCA.

On the doorstep of India

One of the most remarkable discoveries in the recent Narasimhan et al. 2018 preprint has to be the presence of what are essentially Eastern European migrant populations within the Inner Asian Mountain Corridor (IAMC) during the Middle to Late Bronze Age (MLBA). Remarkable for so many reasons, but seemingly under-appreciated by a lot of people, judging by the online discussions that I've seen on
