Ancient man may have also started the domestication process by befriending wolves which helped them hunt and drive herds. There were advantages at that time to having semi-tame wolves. The acute hearing of the wolf would alarm humans of imminent danger at night, for example. Selective breeding has allowed human manipulation to create the traits that you see in dogs today, such as the pushed-in face of the pug, or the speed of the greyhound to catch its prey. Regardless of how far your dog has evolved from its ancestor, there is still a great deal of wolf present in the domestic dog.
Dogs are still genetically wolves, and they share seventy-eight chromosomes.
Besides the physical similarities, there are many behavior similarities between the wolf and the dog. Wolves and dogs live in pack societies. They have group rituals such as greetings, feeding, playing, mating, and hunting. Leading each pack is a dominant male or female. This dog or wolf is known as the alpha.
