Domestication of wolves

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.

How did dogs become domesticated

However, this relationship might represent mitochondrial genome introgression from wolves because dogs were domesticated by this time. He suspects that the process would have begun at the end of the last Ice-Age approximately 15, years ago when people began to gather and live in one place for the first time. The European dog of that period is the one that went on to father most modern dog breeds found today, the researchers concluded. We may never know the exact story of how the first dogs and humans joined forces, but dogs have undoubtedly helped us in countless ways over the years. In , another study indicated 16,, YBP. The appearance of these villages was fairly rapid and coincidental with the fossil evidence of dogs as we know them. Pugs and poodles may not look the part, but if you trace their lineages far enough back in time all dogs are descended from wolves. Radiocarbon dating indicates its age to be 35, YBP, and this age could then be used to re-calibrate the wolf's mutation rate , indicating that the genetic divergence between dogs and wolves occurred before the Last Glacial Maximum, between 40,—27, YBP. Mice also become more social if changes occur to these genes, previous studies have discovered. The study concluded that at least 2 different male haplogroups existed in ancient Europe, and that the dog male lineage diverged from its nearest common ancestor shared with the gray wolf sometime between 68,, YBP.

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.
