Leprosy, a chronic infectious disease caused by Mycobacterium leprae (M. leprae), was very common in Europe till the 16th century. Here, we perform an ancient DNA study on medieval skeletons from Denmark that show lesions specific for lepromatous leprosy (LL). First, we test the remains for M. leprae DNA to confirm the infection status of the individuals and to assess the bacterial diversity. We assemble 10 complete M. leprae genomes that all differ from each other. Second,
The genetic formation of Central and South Asian populations has been unclear because of an absence of ancient DNA. To address this gap, we generated genome-wide data from 362 ancient individuals, including the first from eastern Iran, Turan (Uzbekistan, Turkmenistan, and Tajikistan), Bronze Age Kazakhstan, and South Asia. Our data reveal a complex set of genetic sources that ultimately combined to form the ancestry of South Asians today. We document a southward spread of
Population genomic studies of ancient human remains have shown how modern-day European population structure has been shaped by a number of prehistoric migrations. The Neolithization of Europe has been associated with large-scale migrations from Anatolia, which was followed by migrations of herders from the Pontic steppe at the onset of the Bronze Age. Southwestern Europe was one of the last parts of
I am not a fan of continuity theories – that much should be clear for anyone reading this blog. However, most of such proposals’ supremacist (or rather fear-of-inferiority) overtones don’t mean they have to be wrong. It just means that most of them, most of the time, most likely are.
While reading Tommenable’s comments, I thought about a potential alternative model, where one could a priori accept an identification of North Pontic cultures as ‘Indo-Slavonic’, which seems to be the Eastern European R1a continuist trend right now.
You might expect some rambling about bad journalism here, but I don’t have time to read so much garbage to analyze them all. We have seen already what they did with the “blackness” or “whiteness” of the Cheddar Man: no paper published, just some informal data, but too much sensationalism already.
Despite centuries of research, much about the barbarian migrations that took place between the fourth and sixth centuries in Europe remains hotly debated. To better understand this key era that marks the dawn of modern European societies, we obtained ancient genomic DNA from 63 samples from two cemeteries (from Hungary and Northern Italy) that have been previously associated with the Longobards, a barbarian people that ruled large parts of Italy for over 200 years after invading
NOTE: I know, I know, the Pontic-Caspian steppe is in East Europe, not Asia, but what can you do about people’s misconceptions regarding European geography? After all, the division is a conventional one, there are not many landmarks to divide Eurasia…
BACKGROUND The earliest fossils of Homo sapiens are located in Africa and dated to the late Middle Pleistocene. At some point later, modern humans dispersed into Asia and reached the far-away locales of Europe, Australia, and eventually the Americas. Given that Neandertals, Denisovans, mid-Pleistocene Homo, and H. floresiensis were present in Asia before the appearance of modern humans, the timing and nature of the spread of modern humans across Eurasia continue to be subjects of intense
