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 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]
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]
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]
Here the weight of males was reported at between 45 and 72 kg (99 and 159 lb), while the females were reported at 36 to 60 kg (79 to 132 lb). [12] The Northwestern wolf is also one of the longest wolf subspecies, as its length usually ranges from 5 to 6 ft (152–183 cm) and can reach as long as 7 ft (213 cm). [13] [14]
Baby weighed as appropriate for gestational age. Birth weight is the body weight of a baby at their birth. [1] The average birth weight in babies of European and African descent is 3.5 kilograms (7.7 lb), with the normative range between 2.5 and 4.0 kilograms (5.5 and 8.8 lb). [2]
