Domestication - WikipediaDomestication is a sustained multi-generational relationship in which one group of organisms assumes a significant degree of influence over the reproduction and care of another group to secure a more predictable supply of resources from that second group. Charles Darwin recognized the small number of traits that made domestic species different from their wild ancestors. He was also the first to recognize the difference between conscious selective breeding in which humans directly select for desirable traits, and unconscious selection where traits evolve as a by-product of natural selection or from selection on other traits. There is also such a difference between the domestication traits that researchers believe to have been essential at the early stages of domestication, and the improvement traits that have appeared since the split between wild and domestic populations. The dog was the first domesticated vertebrate,    and was established across Eurasia before the end of the Late Pleistocene era, well before cultivation and before the domestication of other animals. Birds are also widely kept as cagebirds , from songbirds to parrots. The longest established invertebrate domesticates are the honey bee and the silkworm.

The information below is provided as a guide to assist students in engaging appropriately with the course requirements. The University's policy on Assessment for Coursework Programs is based on the following four principles: Assessment must encourage and reinforce learning.
To the greatest extent possible, activities that might be noisy should be conducted in animzl or areas separate from those used for animal housing. Pest Control! The Guide for the Care and Use of Laboratory Animals provides a framework for the judgments required in the management of animal facilities--a resource of proven value, now updated and expanded.

The provision of straw gives an important stimulus and outlet for exploration, foraging, rooting and chewing behaviors. A good understanding of animal behavior is required if we are going to achieve our objective of enabling animals in our care to express their basic behavioral needs Lund and Weary, A basic understanding of natural behavior can be obtained from observing animals under natural conditions or in the wild. Natural behavior can be defined as the repertoire of different behaviors animals show when kept in environments where they can carry out behaviors created in the evolutionary process Lidfors et al. Motivation and innate behaviors are important aspects of natural behavior, and hindering them may lead to abnormal behavior and stress see also Housing and Behavior. Studies of domestic pigs that have escaped back into the wild have shown that their behavior closely resembles that of the European wild boar Sus scrofa from which they originated. An understanding of the natural behavior of pigs can therefore help us to identify and improve pig welfare and to design systems that enhance positive welfare conditions.
However, and behavioral reasons might preclude a successful outcome of this kind of housing, and R. Gordon. Comparison by a cell culture study. Greer.
Research using domestic animals also contributes importantly to the global effort to alleviate poverty and promote human health and this is especially important to prniciples countries 19which relies on farmers for its aninal and dissemination.
