Past studies based on SNPs, genome-wide similarities with Chinese wolves, and lower linkage disequilibrium might reflect regional admixture between dogs with wolves and gene flow between dog populations, with divergent dog breeds possibly maintaining more wolf ancestry in their genome. The study proposed that analysis of ancient DNA might be a ...
In 2013, a mitochondrial DNA sequencing of ancient wolf-like canids revealed another separate lineage of 3 haplotypes (forming a haplogroup) that was found in 3 Late Pleistocene specimens from Belgium; however, it has not been detected in extant wolves. [29] [28] One of these was the "Goyet dog". [29] mDNA phylogenetic tree for wolves. Clades ...
In 2016, a whole-genome DNA study suggested that all of the North American canids, both wolves and coyotes, diverged from a common ancestor 6,000–117,000 years ago. The whole-genome sequence analysis shows that two endemic species of North American wolf, the red wolf and eastern wolf, are admixtures of the coyote and gray wolf. [26] [27]
Another view is that because northern breeds can trace at least some of their ancestry back to the Taimyr wolf, this indicates the possibility of more than one domestication event. [1] In 2020, the nuclear genome was generated of a 33,000 YBP Pleistocene wolf from an archaeological site on the Yana River, arctic northeastern Siberia. The Yana ...
The study also indicated that all North America wolves have a significant amount of coyote ancestry and all coyotes some degree of wolf ancestry, and that the red wolf and eastern wolf are highly admixed with different proportions of gray wolf and coyote ancestry. The study found that coyote ancestry was highest in red wolves from the southeast ...
A DNA analysis showed that it belonged to the Beringian wolf clade, that the most recent common ancestor of this clade dates to 86,700–67,500 YBP, and that this clade was basal to all other wolves except for the Himalayan wolf.

In 2021, researchers sequenced the nuclear DNA (from the cell nucleus) of the dire wolf. The sequences indicate the dire wolf to be a highly divergent lineage which last shared a most recent common ancestor with the wolf-like canines 5.7 million years ago, with morphological similarities with the grey wolf being convergent evolution.
