A 2015 study in Genome Research, for example, estimated that 25 percent of modern
Eurasian wolf DNA actually comes from interbreeding with domesticated dogs.
You really think that a Chihauhua is indistinguishable from
the Eurasian Wolf?
A well recorded, understood, DNA mapped and uncontroversial case of evolution of one sub-species — Canis lupus lupus,
the Eurasian wolf, into another, Canis lupus familiaris, the domestic dog.

Fido's cousins may be
Eurasian wolves, but new findings complicate the details of domestication
The researchers compared the genomes in these individuals to those from pure coyotes and
Eurasian wolves.

Larson takes the findings to suggest that some European

Eurasian domestic dogs whereas some Asian
wolf gave rise to east Asian domestic dogs.
Since the year 2000, the

wolf, Canis lupus lupus, has spread across Germany.
«We were surprised by the results, because we expected a substantial fraction of the genome of the red
wolf and eastern
wolf, maybe 20 % to 30 %, would be derived from a long - distinct species, much as about 1 % to 4 % of [human]
Eurasian genomes derive from Neanderthals,» said Wayne.

Populations of big carnivores such as brown bears,
Eurasian lynx, grey
wolves and wolverines are stable or increasing in a substantial part of Europe.
Despite the evidence of hybridisation among
Eurasian grey
wolves, the
wolf populations have remained genetically distinct from dogs, suggesting that such cross-breeding does not diminish distinctiveness of the
wolf gene pool if it occurs at low levels.
The international study showed that around 60 per cent of
Eurasian grey
wolf genomes carried small blocks of the DNA of domestic dogs, suggesting that
wolves cross-bred with dogs in past generations.
