Drosophila Melanogaster

Humans exploit many animal species for food, both through domesticated livestock and hunting wild marine species. Chickens, cattle, sheep, pigs and other animals are raised as livestock for meat worldwide. Animal fibers, leather, and furs are also obtained from livestock and hunted animals to produce textiles, shoes, coats and other goods. Throughout history, animals have served important economic and scientific roles, including as working animals for agriculture, experimental models in research, and to create vaccines and medicines.

The human population exploits a large number of other animal species for food, both

of domesticated livestock species in animal husbandry and, mainly at sea, by hunting wild species.


[150][151]
 Marine fish of many species are caught commercially for food. A smaller number of species
are farmed commercially.[150][152][153] Invertebrates including cephalopods, crustaceans,
and bivalve or gastropod molluscs are hunted or farmed for food.[154] Chickens, cattle, sheep, pigs
and other animals are raised as livestock for meat across the world. [151][155][156] Animal fibres such as
wool are used to make textiles, while animal sinews have been used as lashings and bindings, and
leather is widely used to make shoes and other items. Animals have been hunted and farmed for
their fur to make items such as coats and hats.[157] Dyestuffs including carmine (cochineal),[158]
[159]
 shellac,[160][161] and kermes[162][163] have been made from the bodies of insects. Working
animals including cattle and horses have been used for work and transport from the first days of
agriculture.[164]
Animals such as the fruit fly Drosophila melanogaster serve a major role in science as experimental
models.[165][166][167][168] Animals have been used to create vaccines since their discovery in the 18th
century.[169] Some medicines such as the cancer drug Yondelis are based on toxins or other
molecules of animal origin.[170]
