Document Summary
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 morphological skeletal and dental features of present domesticated dogs--appear by 15-12,000 ybp in different parts of eurasia and soon thereafter in north america. Three distinct sized dogs at 8,000 ybp from denmark. Before humans mastered selective breeding techniques, distinct dog lineages appeared in different geographic regions through self-selection (or, self- domestication) Humans in different parts of eurasia developed diverse needs for dogs, such as 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 detection, etc. ) Different types of dogs that have adapted to local ecology (use with humans, environment, etc. ) Forest dogs are small, smell well and can help hunters find small game.
