New genomic data suggest that the first human settlers on the Scandinavian peninsula followed two distinct migration routes. The study also indicates that the resulting mixed population genetically adapted to the extreme environmental conditions.

Ancient DNA reveals genetic replacement despite language continuity in the South Pacific
New genetic research reveals the complex demographic history of Vanuatu, explaining how Austronesian languages were retained throughout its history despite near-total replacement of early Austronesian-Lapita with Papuan ancestry Continue reading “Ancient DNA reveals genetic replacement despite language continuity in the South Pacific”
Genomes of five late Neandertals provide insights into Neandertal population history
Researchers at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, have sequenced the genomes of five Neandertals that lived between 39,000 and 47,000 years ago. These late Neandertals are all more closely related to the Neandertals that contributed DNA to modern human ancestors than an older Neandertal from the Altai Mountains that was previously sequenced. Their genomes also provide evidence for a turnover in the Neandertal population towards the end of Neandertal history. Continue reading “Genomes of five late Neandertals provide insights into Neandertal population history”
Ancient DNA tells tales of humans’ migrant history
Scientists once could reconstruct humanity’s distant past only from the mute testimony of ancient settlements, bones, and artifacts. Continue reading “Ancient DNA tells tales of humans’ migrant history”
