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 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 ...
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 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. [75] [76]
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.
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 ...
However, the divergence was a much greater 8.0% between gray wolf (C. lupus) mtDNA and eastern/red wolf haplotypes, and 10.0% between gray wolf and coyote haplotypes. The sequence difference observed between eastern Canadian wolf sequences and coyote sequences is consistent with a separation of 150 000 – 300 000 years, using a divergence rate ...
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 ...
