The genetic difference between domestic and wild populations can be framed within two considerations. The first distinguishes between domestication traits that are presumed to have been essential at the early stages of domestication, and improvement traits that have appeared since the split between wild and domestic populations.
The domestication of vertebrate animals is the relationship between non-human vertebrates and humans who have an influence on their care and reproduction. [7] In his 1868 book The Variation of Animals and Plants Under Domestication, Charles Darwin recognized the small number of traits that made domestic species different from their wild ancestors.
Domestic animals show differences in physical appearance in comparison to their wild ancestors as they underwent some changes such as having floppier ears, bigger skulls, curlier tail and changes in coat colour or pattern, as noted in domestications of dogs and the experimental domesticated red fox in Russia by Dmitry Belyayev.

A lion (Panthera leo).Lions are an example of charismatic megafauna, a group of wildlife species that are especially popular in human culture.. Wildlife refers to undomesticated animals and uncultivated plant species which can exist in their natural habitat, but has come to include all organisms that grow or live wild in an area without being introduced by humans.

A feral pig is a domestic pig that has escaped or been released into the wild, and is living more or less as a wild animal, or one that is descended from such animals. [2] Zoologists generally exclude from the feral category animals that, although captive, were genuinely wild before they escaped. [3]
Wild animals can be tame, such as a hand-raised cheetah. A domestic animal's breeding is controlled by humans and its tameness and tolerance of humans is genetically determined. Thus, an animal bred in captivity is not necessarily domesticated; tigers, gorillas, and polar bears breed readily in captivity but are not domesticated. [5]
Domestication syndrome refers to two sets of phenotypic traits that are common to either domesticated plants [1] [2] or domesticated animals. [3] Domesticated animals tend to be smaller and less aggressive than their wild counterparts; they may also have floppy ears, variations to coat color, a smaller brain, and a shorter muzzle.
