Humans have selected traits in dogs which are characteristic of wolf puppies, such as shortened snouts and smaller size. The oldest dog remains are some 14,000 years old. Juvenile wolf behaviour may have been selected, rather than shape. Wolf pups are scavengers, and this may have led to contact with humans. Primary social bonds are established when the pups are between three-weeks old and 12-weeks-old. Wolf pups that exhibited aggression or failed to bond with humans were probably killed or driven away.
