I'm thrilled that our new article was published today in @AJHGNews. It was an excellent collaboration with @cschlebu, Yoro Diallo, Vaclav Janousek, and Viktor Cerny. Population history and admixture of the Fulani people from the Sahel #Africa #OpenAccess

Here is a nice News piece ( https://t.co/UIk0OnnPZW) by @spoke32 about the work, with a quote from @JoGretzing. 6/6

2000-year-old graves suggest women wielded as much—and sometimes more—power than men in some Celtic tribes

What I get from this is that we should all be more data-mining of published data. There are still hidden gems in there, and as the data is growing faster than people can analyze, the rate of unpublished gems may be growing! 5/6

Turns out the British Iron Age really stands out with its low MT-diversity, being almost uncannily consistent with Roman and other historic writers about Celtic tribes in Britain and their powerful women. Amazing! 4/6

Motivated by this striking discovery, the authors simply check mitochondrial diversity across centuries and in all of Europe from published data, and found a pattern that was there all along but nobody looked for it: 3/6

... with women, daughters and granddaughters all buried at the site. This is the opposite pattern of what we’ve seen in other large-pedigree studies from the Neolithic or later, which are all patrilocal. 2/6

Fascinating study came out two weeks ago by @_larsporsena and Colleagues on a South British Iron Age burial site with an extraordinary matrilocal relatedness pattern ( https://t.co/2z8DZsldbk)... 1/6

"Ancient DNA reveals family ties" is named on of the top 10 Science Break-throughs in 2024 by Science ( https://t.co/Bmwi3e1iWk). Our work on early Celtic princely burials and their discovered close kinship gets mentioned, too!

It was recently reported that Africans experienced a sharp, severe bottleneck around 900kya and that this signal is absent in non-Africans. Here, we present evidence to show why this is likely a statistical artifact: @ras_nielsen @yun_s_song

👏👏 @arevsumer! Contains our IBD analysis led by @YileiHuang317: Multiple really long 20cm++ IBD segments link the two record 45ky-old sequenced modern human sites Zlatý kůň (Czechia) and Ranis (Germany). Showing they are closely related - within few generations. 😮😮 (1/3)
Oldest modern human #genomes sequenced. These seven early #Europeans belonged to a small, isolated group that left no present-day descendants. Study @Nature led by @arevsumer, Kay Prüfer, Johannes Krause @MPI_EVA_Leipzig. https://t.co/thySPSDXyR & https://t.co/IDwbcYjkkF

Out today in @sciencemagazine, we've journeyed into our shared history with Neandertals by analyzing over 300 present-day and ancient modern humans, including 59 individuals who lived between 2,000 and 45,000 years ago. https://t.co/V9OBe4VTjC

Gene flow from Neanderthals has shaped genetic and phenotypic variation in modern humans. We generated a catalog of Neanderthal ancestry segments in more than 300 genomes spanning the past 50,000...
