    Mapping the origins and expansion of the Indo-European language family (2012)
    American Association for the Advancement of Science (AAAS)

    Publication Date: 2012-08-28
    Description: There are two competing hypotheses for the origin of the Indo-European language family. The conventional view places the homeland in the Pontic steppes about 6000 years ago. An alternative hypothesis claims that the languages spread from Anatolia with the expansion of farming 8000 to 9500 years ago. We used Bayesian phylogeographic approaches, together with basic vocabulary data from 103 ancient and contemporary Indo-European languages, to explicitly model the expansion of the family and test these hypotheses. We found decisive support for an Anatolian origin over a steppe origin. Both the inferred timing and root location of the Indo-European language trees fit with an agricultural expansion from Anatolia beginning 8000 to 9500 years ago. These results highlight the critical role that phylogeographic inference can play in resolving debates about human prehistory.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4112997/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4112997/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bouckaert, Remco -- Lemey, Philippe -- Dunn, Michael -- Greenhill, Simon J -- Alekseyenko, Alexander V -- Drummond, Alexei J -- Gray, Russell D -- Suchard, Marc A -- Atkinson, Quentin D -- 260864/European Research Council/International -- R01 GM086887/GM/NIGMS NIH HHS/ -- R01 HG006139/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2012 Aug 24;337(6097):957-60. doi: 10.1126/science.1219669.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Computer Science, University of Auckland, Auckland 1142, New Zealand.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22923579" target="_blank"〉PubMed〈/a〉

    Language phylogenies reveal expansion pulses and pauses in Pacific settlement (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-01-24
    Description: Debates about human prehistory often center on the role that population expansions play in shaping biological and cultural diversity. Hypotheses on the origin of the Austronesian settlers of the Pacific are divided between a recent "pulse-pause" expansion from Taiwan and an older "slow-boat" diffusion from Wallacea. We used lexical data and Bayesian phylogenetic methods to construct a phylogeny of 400 languages. In agreement with the pulse-pause scenario, the language trees place the Austronesian origin in Taiwan approximately 5230 years ago and reveal a series of settlement pauses and expansion pulses linked to technological and social innovations. These results are robust to assumptions about the rooting and calibration of the trees and demonstrate the combined power of linguistic scholarship, database technologies, and computational phylogenetic methods for resolving questions about human prehistory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gray, R D -- Drummond, A J -- Greenhill, S J -- New York, N.Y. -- Science. 2009 Jan 23;323(5913):479-83. doi: 10.1126/science.1166858.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, University of Auckland, Private Bag 92019, Auckland 1142, New Zealand.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19164742" target="_blank"〉PubMed〈/a〉
