Document Summary
Main points: dogs with features like modern domesticated dogs present in archeological record by 15-12000 bp. Genetic data from modern wolves and dogs and archeological evidence, confirm that dogs arose from separate stocks of european and asian wolves. Domesticated dogs- with the morphological skeletal and dental features of present domesticated dogs appear by. 15-12000 bp in different parts of eurasia and soon thereafter in north america. 3 distinct sized dogs at 8000 bp from denmark. Before humans mastered selective breeding techniques, distinct dogs lineages appeared in different geographic regions through self selection or self domestication. Humans in different parts of eurasia developed diverse needs for dogs, such hunting, transport, protection, herding, etc. Through self selection over several hundred years human needs became matched to the relevant dog characteristics (running speed, body size, scent) ---- land races. Difficult to keep wild canids (wolves and related carnivores) from opportunistically interbreeding with the self domesticated breeds so long as humans were mobile hunter-gatherers.
