It is possible that wolves took advantage of resources that humans had, or humans may have been introduced to wolves in an area in which they didn't previously live. The oldest fossils generally agreed to be domestic dogs date to about 14, years, but several disputed fossils more than twice that age may also be dogs or at least their no longer entirely wolf ancestors.
The range of natural variation among these characters that may have existed in ancient wolf populations, and the time it took for these traits to appear in dogs, are unknown.

Archaeologist Robert Losey and associateswho conducted this study, suggest that these are indications that Kitoi hunter-gatherers considered that at least these individual dogs were "persons". When and where were dogs domesticated? But when this partnership first occurred is still under some debate.
This is complicated further by the cross-breeding that has occurred between dogs and wolves since domestication referred to as post-domestication gene flow. A 20th century Russian Geneticist, Dmitri Belyaev, was able to solve part of the mystery surrounding how a wolf made such a drastic transformation.
Dogs as Persons Some studies of dog burials dated to the Late Mesolithic-Early Neolithic Kitoi period in the Cis-Baikal region of Siberia suggests that in some cases, dogs were awarded "person-hood" and treated equally to fellow humans.
