Parallel palaeogenomic transects reveal complex genetic history of early European farmers

last monthAcademics : Nature AOP

Ancient DNA studies have established that Neolithic European populations were descended from Anatolian migrants who received a limited amount of admixture from resident hunter-gatherers. Many open questions remain, however, about the spatial and temporal dynamics of population interactions and admixture during the Neolithic period. Show More Summary

Ancient DNA offers new view on saber-toothed cats' past

Researchers who've analyzed the complete mitochondrial genomes from ancient samples representing two species of saber-toothed cats have a new take on the animals' history over the last 50,000 years. The data suggest that the saber-toothed cats shared a common ancestor with all living cat-like species about 20 million years ago. Show More Summary

Humans no longer have ancient defence mechanism against viruses

Insects and plants have an important ancient defence mechanism that helps them to fight viruses. This is encoded in their DNA. Scientists have long assumed that vertebrates - including humans - also had this same mechanism. But researchers at KU Leuven (University of Leuven), Belgium, have found that vertebrates lost this particular asset in the course of their evolution.
