Ancient agricultural DNA everywhere
Heady days for ancient DNA researchers. There have been two major papers in the past month looking at the DNA of Neolithic farmers. Back in June, a huge research consortium published “The genetic structure of the world’s first farmers” as a preprint in bioRxiv, with subsequent write-up in Nature. And now a different huge consortium comes out with “Early Neolithic genomes from the eastern Fertile Crescent,” in Science. That also got widely picked up.
Don’t ask me why two separate research groups need to be working on basically the same problem, in basically the same way. I suppose they’re using somewhat different methods on different material. I really couldn’t tell you whether it would have been better to pool the material, or standardize the methods, or indeed both. Maybe someone out there will tell us. In any case, it’s reassuring, I suppose, that the two studies came to broadly similar conclusions, namely that there were genetic differences among early farmers, and that genetically distinct people from different parts of the Fertile Crescent migrated north into Europe and eastwards further into Asia. Which in turn suggests to some that the origins of agriculture may be described as “federal”:
Different and genetically distinct populations were all engaged in this same general project, albeit exchanging ideas with each or other or sometimes coming up with the same idea independently.
Meanwhile, sequencing of DNA from a 6000-year-old barley from the Dead Sea shows close similarity with varieties still grown in the southern Levant and Egypt. Intriguing to speculate whether a similar study of material from the Zagros Mountains would show a parallel pattern to the human DNA. But will it need a different group of researchers to do it.

- Desertification may not be a thing.
- Biodiversity loss is, though, right?
