**Ancient genomes reveal trans-Eurasian connections between the European Huns and the Xiongnu Empire**

_“We provide new compelling evidence on the origins of the Hun-period population, its considerable diversity and its ties to the steppe and the Xiongnu elites.”_

**Inference of human pigmentation from ancient DNA by genotype likelihood**

_“We then applied that protocol to 348 ancient genomes from Eurasia, describing how skin, eye and hair color evolved over the past 45,000 years. The shift towards lighter pigmentations turned out to be all but linear in time and place, and slower than expected, with half of the individuals showing dark or intermediate skin colors well into the Copper and Iron ages.”_

Our last #commonancestor lived 4.2 billion years ago—perhaps hundreds of millions of years earlier than thought
#Genomes of diverse #microbes point to early #evolution of a rudimentary #immunesystem
The last ancestor shared by all living organisms was a microbe that lived 4.2 billion years ago, had a fairly large #genome encoding some 2600 proteins, enjoyed a diet of hydrogen gas and carbon dioxide, and harbored a rudimentary immune system for fighting off viral invaders.

**Ancient genomes reveal Avar-Hungarian transformations in the 9th-10th centuries CE Carpathian Basin**

_“Our evaluations reveal spatially different histories in Transdanubia even between communities in close geographical proximity, highlighting the importance of dense sampling and analyses. Our findings highlight extensive homogenization and reorganization processes, as well as discontinuities between Hun, Avar, and Hungarian conquest period immigrant groups, alongside the spread and integration of ancestry related to the Hungarian conquerors.”_
