Changes in the size and proportions of the body

Dwarf and giant forms have developed as a result of domestication. In the early phases of domestication the overall size of the body decreased (cattle, goat, sheep). This change is attributed to premeditated selection (easier control and housing of smaller individuals) combined with inadequate food. Extra long ears also appeared (dog, sheep, pig, cattle, cat, rabbit), curled tails (dog, pig), or very short tails (dog, cat, sheep). Horns also became variable in size and curvature, totally disappearing in some species (cattle, sheep, goat).
