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]
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 ...
Ambulocetus (Latin ambulare "to walk" + cetus "whale") is a genus of early amphibious cetacean [a] from the Kuldana Formation in Pakistan, roughly 48 or 47 million years ago during the Early Eocene . It contains one species , Ambulocetus natans (Latin natans "swimming"), known solely from a near-complete skeleton.
Rodhocetus was a small whale measuring 2–3 m (6.6–9.8 ft) long. [4] Throughout the 1990s, a close relationship between cetaceans and mesonychians, an extinct group of cursorial, wolf-like ungulates, was generally accepted based on morphological analyses. In the late 1990s, however, cladistic analyses based on molecular data clearly placed ...
Archaeoceti ("ancient whales"), or Zeuglodontes in older literature, is a paraphyletic group of primitive cetaceans that lived from the Early Eocene to the late Oligocene 1] Representing the earliest cetacean radiation , they include the initial amphibious stages in cetacean evolution , thus are the ancestors of both modern cetacean suborders ...
Reintroduction of wolves. Wolves were reintroduced to the park in 1995, after being driven extinct in the area nearly 100 years ago. It is estimated that approximately 500 wolves are present now ...
A California gray wolf, dubbed OR 85, in 2023. The wolf was fitted with a satellite collar to help the California Department of Fish and Wildlife track the state's burgeoning wolf population.
The wolves of MIS 3 were smaller in body size than MIS 5 wolves and those found in Sweden today. These wolves were out-competed by the lion and hyena, leading to a more omnivorous diet with increased crushing ability in an open environment that supported more types of prey and more non-meat foods than the MIS 5 period.
