Urban environments often favor coyote genes, while the ones in the rural and deep forest areas maintain higher levels of wolf content. A 2016 meta-analysis of 25 genetics studies from 1995 to 2013 found that the northeastern coywolf is 60% western coyote, 30% eastern wolf, and 10% domestic dog.
This canine has been named Canis latrans var. [3] and has been referred to as the eastern coyote, northeastern coyote, coywolf, [4] and the southern tweed wolf. [5] [6] Coyotes and wolves first hybridized in the Great Lakes region, followed by a hybrid coyote expansion that created the largest mammalian hybrid zone known. [7]
The comparison indicated that the red wolf was about 76% coyote and 24% gray wolf with hybridization having occurred 287–430 years ago. The eastern wolf – which was referred to as the "Great Lakes" wolf in this study – was 58% gray wolf and 42% coyote with hybridization having occurred 546–963 years ago.
The eastern wolf probably was a result of a wolf-coyote admixture, combined with extensive backcrossing with parent gray wolf populations. The red wolf may have originated during a time of declining wolf populations in the Southeastern Woodlands, forcing a wolf-coyote hybridization, as well as backcrossing with local parent coyote populations ...
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 red wolf is an enigmatic taxon, of which there are two proposals over its origin. One is that the red wolf is a distinct species (C. rufus) that has undergone human-influenced admixture with coyotes. The other is that it was never a distinct species but was derived from past admixture between coyotes and gray wolves, due to the gray wolf ...
Neither Wile E. Coyote nor lawyer Will Forte look at all confident about their case in a first photo from Coyote vs. ACME, the live-action/animation hybrid film that Warner Bros. recently decided ...
The taxonomic status of the red wolf is debated. It has been described as either a species with a distinct lineage, [73] a recent hybrid of the gray wolf and the coyote, [10] an ancient hybrid of the gray wolf and the coyote which warrants species status, [74] or a distinct species that has undergone recent hybridization with the coyote.
