Abstract:	Despite the large body of research devoted to understanding the role of Quaternary glacialcycles in the genetic divergence of European trees, the differential contribution of geographicisolation and/or environmental adaptation in creating population genetic divergence remainsunexplored. In this study, we used a long-lived tree (Taxus baccata) as a model species toinvestigate the impact of Quaternary climatic changes on genetic diversity via neutral (isola-tion-by-distance) and selective (isolation-by-adaptation) processes. - We applied approximate Bayesian computation to genetic data to infer its demographic his-tory, and combined this information with past and present climatic data to assess the role ofenvironment and geography in the observed patterns of genetic structure. -We found evidence that yew colonized Europe from the East, and that European samplesdiverged into two groups (Western, Eastern) at the beginning of the Quaternary glaciations,c. 2. 2 Myr before present. Apart from the expected effects of geographical isolation duringglacials, we discovered a significant role of environmental adaptation during interglacials atthe origin of genetic divergence between both groups. -This process may be common in other organisms, providing new research lines to explorethe effect of Quaternary climatic factors on present-day patterns of genetic diversity.
