Eurasian Grey and White wolf ancestors—800,000 years evolution, adaptation, pathologies and European dog origins

Abstract

The oldest known wolf appears 800,000 years ago (Marine Isotope Stage 21) in Eurasia with the unspecialized short-legged old Mammoth steppe wolf Canis lupus bohemica nov. spec. From this species, about 600,000–420,000 years ago (MIS 15-11), the interglacial Canis lupus mosbachensis (Soergel, 1925) short-legged Mosbach grey wolf subspecies roamed Eurasia. In the late Middle Pleistocene, there are two lineages, the southern interglacial grey and northern glacial White wolves in Eurasia. Since 320,000 (MIS 8), the short-legged White wolf Canis lupus spelaeus (Goldfuss, 1823) was the glacial Mammoth steppe-adapted wolf. Parallel to the “cave wolf” (found in the German Zoolithen Cave), the warm climate grey wolf Canis lupus brevis Kuzmina and Sablin, 1994 existed. C. l. spelaeus relates to the Holocene (MIS 1) extant Holarctic Greenland Canis lupus arctos and Siberian Canis lupus albus (Kerr, 1792). The Late Palaeolithic (MIS 2) “Gravettian Goyet dogs” fall into the DNA pool of C. l. spelaeus and are identified herein as pathological bite trauma individuals, which braincase shortened during the healing process. European prehistoric Neolithic dogs seem to have been imported from Central Asia with the Bandkeramik people (approx. 7000 BP) first, which have the stepped frontals originating from grey wolves.
