In May 2011, an examination of 48,000 single nucleotide polymorphisms in red wolves, eastern wolves, gray wolves, and dogs indicated that the red and eastern wolves were hybrid species, with the red wolf being 76% coyote and 20% gray wolf, and the eastern wolf being 58% gray wolf and 42% coyote, finding no evidence of being distinct species in ...
The gray wolves (Canis lupus) of Isle Royale National Park, Michigan, US, were a small highly inbred population that was considered to be at the threshold of extinction in 2019. [30] This wolf population had been experiencing severe inbreeding depression largely due to the homozygous expression of strongly deleterious recessive mutations .
The coyote is typically smaller than the gray wolf, but has longer ears and a relatively larger braincase, [7] as well as a thinner frame, face, and muzzle. The scent glands are smaller than the gray wolf's, but are the same color. [9] Its fur color variation is much less varied than that of a wolf. [13]
The wolf (Canis lupus; [b] pl.: wolves), also known as the grey wolf or gray wolf, is a canine native to Eurasia and North America. More than thirty subspecies of Canis lupus have been recognized, including the dog and dingo , though grey wolves, as popularly understood, only comprise naturally-occurring wild subspecies.

True members of Canis, namely the gray wolf and coyote, likely only arrived in the New World during the Late Pleistocene, where their dietary flexibility and/or ability to hybridize with other canids allowed them to survive the Quaternary extinction event, unlike the dire wolf. [14] Xenocyon (strange wolf) is an extinct subgenus of Canis. [15]
The latest wildlife mystery in Nevada has been solved. DNA testing confirmed the results with 99.9% certainty, the Nevada Department of Wildlife announced this week. The sighting in northeast ...
The proposed timing of the wolf/coyote divergence conflicts with the finding of a coyote-like specimen in strata dated to 1 million years before present. [41] In 2017 a group of canid researchers challenged the 2016 whole-genome DNA study's finding that the red wolf and the eastern wolf were the result of recent coyote–gray wolf hybridization.
