Dog Cages

As humans migrated around the planet, a conglomeration of dog forms migrated with them. The agricultural revolution and sequent urban revolution led to an increase in the dog population and a demand for specialization. These circumstances would provide the opportunity for choicy breeding to compose specialized working dogs and pets.

The relationship between human and canine derelict broad roots. Converging archaeological and genetic evidence indicate a time of domestication in the blown Upper Paleolithic close to the Pleistocene/Holocene boundary, between 17,000 and 14,000 years ago. Fossil bone morphologies and genetic analysis of in progress and ancient dog and wolf populations have not yet been able to conclusively determine whether all dogs descend from a original domestication event, or whether dogs were domesticated independently in further than particular location. Domiciliary dogs may have interbred with local populations of escaped wolves on manifold occasions (a advance known in genetics Dog Cages as introgression).
