For biologists, the 45 or so species of deer -- many very different from each other -- are all artiodactyl
ungulate ruminants of the Cervidaefamily, lacking upper incisors and a gall bladder.

Cattle/buffalo and sheep/goat categories may include some bone fragments from similarly-sized wild artiodactyls
About 60 years ago, researchers first suggested that cetaceans were related to plant-eating ungulates, specifically to even-toed, artiodactyl
mammals like sheep, antelope and pigs.
The ancestors of artiodactyls
, the group that includes gazelles, cattle, and most of today's other large herbivores, appeared during this interval.
The results of a study of the patterns of a certain type of genomic change, called transposon insertions, among thirteen vertebrate species supported an earlier proposal of evolutionary trees showing that primates (human, chimpanzee, baboon) are more closely related to rodents like the mouse and rat than to carnivores like the cat and dog or artiodactyls
like the cow and pig.
However, the NHGRI studies indicate that the genomes of rodents are mutating faster than those of primates, carnivores, or artiodactyls
(a type of ungulate).
Interspecific competition between four exotic species and native artiodactyls
in the United States.
Several records show that rodents, lagomorphs and artiodactyls
derive minerals directly from rocks.
Sung," used as the alternative past tense of "sing," is a vehicle especially popular with the obtruding artiodactyls
We believe that similar distributional patterns can be found and documented in expanding populations of carnivores and artiodactyls
, such as the least weasel, Mustela nivalis, which is expanding south and west; white-tailed deer, Odocoileus virginiana, which is expanding westward; and moose, Alces alces, which is expanding southward.
1991) determined that the guinea pig diverged prior to the separation of primates and artiodactyls
(even-toed ungulates: cow and pig) from myomorphic rodents (rats and mice).
The disease mainly affects cattle, sheep, pigs, camels, and other artiodactyls
There is considerable osteological variability within, and overlap between, the postcranially similar-shaped and similarsized artiodactyls
, pronghorns (including Antilocapra, Tetrameryx, and Stockoceros), mule deer (Odocoileus hemionus), white-tailed deer (Odocoileus virginianus), and bighorn sheep (Ovis canadensis).
Some 30 new rodents, carnivores, primates and artiodactyls
(the group that includes sheep, goats, camels, pigs, cows, deer, giraffes and antelopes, among others) appeared on the scene.
