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 ...
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 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]
The coyotes from Alaska, California, Alabama, and Quebec show almost no wolf ancestry. Coyotes from Missouri, Illinois, and Florida exhibit 5–10% wolf ancestry. There was 40%:60% wolf to coyote ancestry in red wolves, 60%:40% in eastern wolves, and 75%:25% in the Great Lakes wolves.
In 2020, a study conducted DNA sequencing of canines across southeastern US to detect those with any red wolf ancestry. The study found that red wolf ancestry exists in the coyote populations of southwestern Louisiana and southeastern Texas, but also newly detected in North Carolina. The red wolf ancestry of these populations possess unique red ...
Legislation proposed in Albany would require DNA testing of canids killed in New York state weighing over 50 pounds to determine if it is a wolf.
Canis edwardii, also known as Edward's wolf, [2] is an extinct species of wolf in the genus Canis which was endemic to North America three million years ago from the Late Blancan stage of the Pliocene epoch and was extinct by the end of the Irvingtonian stage of the Pleistocene epoch.
