Ancient DNA reveals Maya collapse was a transformation, not extinction

A new genetic study is rewriting the history of the collapse of the Classic Maya civilization, revealing that even though city-states such as Copán and others experienced severe population depletion around 1,200 years ago, the Maya themselves never disappeared. Published on May 28 in Current Biology, the research, led by Shigeki Nakagome, an assistant professor of genomic medicine at Trinity College Dublin, sheds light on the continuity and resilience of the Maya people through one of the most dramatic societal transformations of ancient times...

Genetic study reveals origin and diversity of Huns

The origins of the Huns, the formidable nomad warriors who changed European history in the late fourth century, have been a topic of discussion among scholars. In the past, experts thought the Huns descended from the Xiongnu, an empire that ruled the Mongolian steppe but collapsed around 100 CE. However, the 300-year gap between the Xiongnu’s collapse and the emergence of the Huns in Europe has been a mystery in history. A recent genetic study now sheds new light on this old question.

A team of geneticists, archaeologists, and historians conducted an analysis of 370 ancient genomes. These samples span about 800 years, from 200 BCE to 600 CE. The research didn’t find evidence of a large, united group of Asian or steppe origin among the Huns in the Carpathian Basin. Instead, the genetic landscape was diverse, hinting that the Huns didn’t arrive as a single migrating group but as a mix of different peoples. However, a few people buried in elite “eastern-type” graves—often linked to nomadic traditions—showed clear East Asian genetic markers...

Ancient genomics reveal the origins of Italo-Celtic and Graeco-Armenian languages

A new study revealed key insights about Mediterranean language families’ origins, including Italo-Celtic and Graeco-Armenian branches of Indo-European. An international team of geneticists and archaeologists conducted this research. They examined how ancient migrations influenced the emergence of linguistic groups that shaped Mediterranean civilizations.

The team published their findings on the preprint server bioRxiv. They analyzed genetic data from 314 ancient individuals who lived in the Mediterranean 5,200 to 2,100 years ago. The researchers used advanced genome sequencing and strontium isotope analysis. This revealed significant genetic and cultural differences between eastern and western Mediterranean populations.

DNA evidence rewrites history of Pompeii victims buried in volcanic eruption

A recent study led by an international team of researchers has unveiled new insights into the victims of Pompeii, challenging longstanding assumptions about the identities and relationships of those entombed by the catastrophic eruption of Mount Vesuvius in 79 CE. This research, published on November 7, 2024, in Current Biology, relies on ancient DNA extracted from skeletal remains within the plaster casts that have preserved the forms of Pompeii’s residents for nearly two millennia.

For centuries, scholars have examined these casts, attempting to deduce the victims’ relationships and stories based on physical proximity, attire, and positioning at the time of their deaths. Traditional interpretations often assumed family connections based on these factors. For instance, an adult wearing a golden bracelet and holding a child was widely believed to be a mother with her child. However, DNA evidence now reveals that this adult was an unrelated male holding a child, dismantling this long-standing interpretation. Similarly, two individuals found in a close embrace, once thought to be sisters or a mother and daughter, were found to include at least one genetic male...

Scandinavia’s early farmers slaughtered the hunter-gatherer population 5,900 years ago

A recent study conducted by Lund University in Sweden challenges previously held beliefs regarding the transition from hunter-gatherer to agricultural societies in Scandinavia.

The research, which involved an international team of scientists, utilized DNA analysis of skeletons and teeth dating back 7,300 years found in present-day Denmark. Contrary to prior assumptions, the study reveals not one but two significant population turnovers occurred in the region, reshaping the genetic landscape and rewriting the history of ancient migrations.

Previous narratives portrayed this transition as peaceful, but the study suggests the farmers, originating from Anatolia and southern Russia, drove out the indigenous hunter-gatherer populations through a combination of violence and the introduction of new pathogens from their livestock...

These tests also do some frankly bizarre 'trait' analysis which seems a little sketchy to me. Apparently I'm less likely to get hangry (true), a night owl (true), less likely to enjoy dancing (?! and false) and unlikely to enjoy coriander (true) as well as a bunch of other things. Also, spoiler alert, I'm a blonde/red head with freckles and straight hair. #DNAanalysis

@medievalists Interesting article, & use of DNA analysis! Chess pieces made of horse, cow & deer bones - and "fashioned by groups (of pawns, of rooks, of bishops and knights and of queens and kings), which testifies to planned, routine activity, probably in a specialized workshop."
