Cave Bear ancestors

Abstract

[Abstract] The lineage of the cave bear Ursus deningeri--> U. Spelaeus is well known, but to draw a limit in this evolution is not easy. The real difficulty is met when this cave bear lineage has to be linked to its ancestors... Dating physical methods, paleoclimatic and paleo environmental data, works on teeth and bones morphology, progress in paleogenetics are means our disposal to give essential information to phylogeny. A large collaboration is needed. Practical information are given about a possible discussion group
