Animal science is described as "studying the biology of animals that are under the control of humankind". It can also be described as the production and management of farm animals. [ 1 ] Historically, the degree was called animal husbandry and the animals studied were livestock species, like cattle , sheep , pigs , poultry , and horses .
The human population exploits a large number of non-human animal species for food, both of domesticated livestock species in animal husbandry and, mainly at sea, by hunting wild species. [ 6 ] [ 7 ] Marine fish of many species, such as herring , cod , tuna , mackerel and anchovy , are caught and killed commercially, and can form an important ...
The close link between human health and ecological/faunal health is substantiated with five important concepts: animals cause and disseminate disease for humans and vice versa, animals can be guards of human health, animals are used in traditional medicine practices throughout the world, animals are a source of drugs and treatments in human ...

World Animal Protection's objectives include helping people understand the critical importance of good animal welfare, encouraging nations to commit to animal-friendly practices, and building the scientific case for the better treatment of animals. They are global in a sense that they ...
[88] [89] In artificial selection, animals were selectively bred for specific traits. [90] Given that traits are inherited, populations contain a varied mix of traits, and reproduction is able to increase any population, Darwin argued that in the natural world, it was nature that played the role of humans in selecting for specific traits.

In 2012, Understanding Animal Research, responding to a small dip in public support for animal research, [14] announced the Declaration of Openness with 41 organisations, including charities, pharmaceuticals and universities, promising to take part "in an ongoing conversation about why and how animals are used in research and the benefits of ...
Biodiversity is the result of 3.5 billion years of evolution. [102] The origin of life has not been established by science, however, some evidence suggests that life may already have been well-established only a few hundred million years after the formation of the Earth.
