An analysis of ancient DNA recreates the genetic history of Portugal and Spain

The genomes of individuals who lived on the Iberian Peninsula in the Bronze Age had minor genetic input from Steppe invaders, suggesting that these migrations played a smaller role in the genetic makeup and culture of Iberian people, compared to other parts of Europe. Daniel Bradley and Rui Martiniano of Trinity College Dublin, in Ireland, and Ana Maria Silva of University of Coimbra, Portugal, report these findings July 27, 2017 in PLOS Genetics.

Scientists discover genomic ancestry of Stone Age North Africans from Morocco

An international team of researchers, led by Johannes Krause and Choongwon Jeong from the Max Planck Institute for the Science of Human History (Jena, Germany), and Abdeljalil Bouzouggar from the Institut National des Sciences de l’Archéologie et du Patrimoine (Rabat, Morocco) and including scientists from the Mohammed V University in Rabat, the Natural History Museum in London, University of Oxford, Université Mohammed Premier in Oujda and the Max Planck Institute for Evolutionary Anthropology in Leipzig, have sequenced DNA from individuals from Morocco dating to approximately 15,000 years ago, as published in Science.

Europeans: there has been no long-term genome-wide removal of Neandertal DNA

A team of researchers at the Max Planck Institute for Evolutionary Anthropology (Martin Petr, Svante Pääbo, Janet Kelso, and Benjamin Vernot) has found evidence that suggests there has been no long-term removal of Neanderthal DNA from modern Europeans. Here we present a small part of their paper titled “Limits of long-term selection against Neandertal introgression“.
