Free access articles from PNAS

This week’s PNAS early edition (Proceedings of the National Academy of Sciences) for 29th October 2012 offers some really interesting articles as open access articles:

  • Joaquim Fort, University of Girona, Spain looks at the Neolithic transition models (demic and cultural model) of the European Neolithic transition from a physicist’s viewpoint: Synthesis between demic and cultural diffusion in the Neolithic transition in Europe’ (PNAS article)
  • Michael Storey from the Roskilde University in Denmark and his colleagues succeeded in a much more precise dating of the Toba supereruption in Sumatra by 40Ar/39Ar dating of sanidine crystals. Apart from a global synchronization for a time period beyond the range of 14C dating they also reflect on the consequences for the peopling of Southeast Asia by Homo sapiens. (PNAS article)
  • Jean-Jacques Hublin and team from the Max-Planck-Institute for Evolutionary Anthropology in Leipzig report new radiocarbon dates from the Grotte du Renne and Saint-Césaire which support an Neanderthal origin of the Châtelperronian. They also demonstrate that the Neanderthal production of body ornaments postdate the arrival of modern humans in neighbouring areas and therefore is probably based on cultural diffusion (PNAS article)
  • Also of interest is an article by William Forde Thompson and al. (Macquarie University, Sydney) about a musical protolanguage hypothesis: music and language share mechanisms that trigger emotional responses to acoustic attributes, as predicted by theories that propose a common evolutionary link (PNAS article)
  • Michael Knapp et al. from the Departments of Anatomy and Anthropology and Archaeology at the University of Otago, Dunedin, New Zealand present a complete mitochondrial genome sequence from the likely founding population of Aotearoa/New Zealand, recovered from the site of Wairau Bay. Their data provide some insights into the genetic diversity of human populations in the Pacific at the time of the settlement of East Polynesia (PNAS article)

Quite an offer🙂 Thank you PNAS!
