The traditional hypothesis of cetacean evolution, first proposed by Van Valen in 1966, [9] was that whales were related to the mesonychians, an extinct order of carnivorous ungulates (hoofed animals) that resembled wolves with hooves and were a sister group of the artiodactyls (even-toed ungulates). This hypothesis was proposed due to ...
The New World wolves did not show any gene flow with the boxer, dingo or Chinese indigenous dogs but there was indication of gene flow between the Mexican wolf and the African basenji. [13] All species within the genus Canis, the wolf-like canids, are phylogenetically closely related with 78 chromosomes and can potentially interbreed. [100]

South American foxes look like true foxes, despite being a unique canid genus more closely related to wolves and jackals. [60] Whales exhibit hyperphalangy—an increase in the number of phalanges beyond three phalanges-per-digit. Whales share this characteristic with extinct marine reptiles, but not present-day marine mammals. [61]
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.
The name Whippomorpha is a combination of Ancient Greek and Latin (w[water] + hippo[horse]) and μορφή (morphē), meaning "living being". [2] Some attempts have been made to rename the suborder Cetancodonta, due to the misleading utilization of the suffix -morpha for a crown group, [6] as well as the risk of confusion with the clade Hippomorpha (which consists of equid perissodactyls); [7 ...
California wildlife officials recently outfitted 12 gray wolves with satellite collars, allowing enhanced monitoring of the population that has started to take off in recent years.
