Usually this male and female are the only animals of the pack to breed. All of a pack's adults help to care for young In 1993, a study of the wolf-like canids found that there was a close kinship between domestic dogs, gray wolves, coyotes and Simien jackals but with a distance from the African wild dog and from the golden, side-striped and black-backed jackals. The domestic dog was an extremely close relative of the gray wolf, differing from it by at most 0.2% of the maternal mitochondrial Cytochrome b gene marker. In comparison, the gray wolf differs from its closest wild relative, the coyote, by about 4%. Therefore, the study concluded that the molecular genetic evidence did not support theories that dogs arose from jackal ancestors. The study proposed the hypothesis that because of the diversity of dog remains found in archaeological sites, that dogs may be derived from several different ancestral gray wolf populations. Later that year, the domestic dog Canis familiar is was reclassified as Canis lupus familiar is, a subspecies of Canis lupus in Mammal Species of the World.[26][76]pups by bringing them food and watching In 1999, a review of the scientific literature regarding the genetic origin of the dog proposed a number of hypotheses. The molecular data indicated that dogs have protein alleles in common with wolves, share highly polymorphic…
