An omnivore (/ ˈ ɒ m n ɪ v ɔːr /) is an animal that regularly consumes significant quantities of both plant and animal matter. [ 3 ] [ 4 ] Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates , protein , fat , and fiber , and metabolize the nutrients and energy of the sources absorbed. [ 5 ]
Their molecular phylogeny shows the extant Carnivora are a monophyletic group, the crown group of the Carnivoramorpha. [35] From there carnivorans have split into two clades based on the composition of the bony structures that surround the middle ear of the skull, the cat-like feliforms and the dog-like caniforms .

Anserimimus (/ ˌ æ n s ər ɪ ˈ m aɪ m ə s / AN-sər-im-EYE-məs; "goose mimic") is a genus of ornithomimid theropod dinosaur, from the Late Cretaceous Period of what is now Mongolia.It was a lanky, fast-running animal, possibly an omnivore.
Most bears are opportunistic omnivores and consume more plant than animal matter, and appear to have evolved from an ancestor which was a low-protein macronutrient omnivore. [67] They eat anything from leaves, roots, and berries to insects, carrion, fresh meat, and fish, and have digestive systems and teeth adapted to such a diet. [58]
The evolution of the digestive system has formed a significant influence in mammal evolution. With the emergence of mammals, the digestive system was modified in a variety of ways depending on the animal's diet. For example, cats and most carnivores have simple large intestines, while the horse as a herbivore has a voluminous large intestine. [127]
The recent evolution of procyonids has been centered on Central America (where their diversity is greatest); [14] they entered the formerly isolated South America as part of the Great American Interchange, [15] beginning about 7.3 Ma ago in the late Miocene, with the appearance of Cyonasua. [16]
Canidae (/ ˈ k æ n ɪ d iː /; [3] from Latin, canis, "dog") is a biological family of dog-like carnivorans, colloquially referred to as dogs, and constitutes a clade.A member of this family is also called a canid (/ ˈ k eɪ n ɪ d /). [4]
