Beschreibung:
The mammoth lineage provides an example of rapid adaptive evolution in response to the changing environments of the Pleistocene. Using well-dated samples from across the mammoth's Eurasian range, we document geographical and chronological variation in adaptive morphology. This work illustrates an incremental (if mosaic) evolutionary sequence but also reveals a complex interplay of local morphological innovation, migration, and extirpation in the origin and evolution of a mammalian species. In particular, northeastern Siberia is identified as an area of successive allopatric innovations that apparently spread to Europe, where they contributed to a complex pattern of stasis, replacement, and transformation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lister, A M -- Sher, A V -- New York, N.Y. -- Science. 2001 Nov 2;294(5544):1094-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University College London, London WC1E 6BT, UK. a.lister@ucl.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11691991" target="_blank"〉PubMed〈/a〉
