Most animal testing involves invertebrates, especially Drosophila melanogaster, a fruit fly, and Caenorhabditis elegans, a nematode. These animals offer scientists many advantages over vertebrates, including their short life cycle, simple anatomy and the ease with which large numbers of individuals may be studied.
Animal testing, science, medicine, animal welfare, animal rights, ethics Animal testing , also known as animal experimentation , animal research , and in vivo testing , is the use of non-human animals , such as model organisms , in experiments that seek to control the variables that affect the behavior or biological system under study.
Fortrea primate-testing lab, Vienna, Virginia, 2004–05. Most of the NHPs used are one of three species of macaques, accounting for 79% of all primates used in research in the UK, and 63% of all federally funded research grants for projects using primates in the U.S. [25] Lesser numbers of marmosets, tamarins, spider monkeys, owl monkeys, vervet monkeys, squirrel monkeys, and baboons are used ...
In 1954, the Universities Federation for Animal Welfare (UFAW) decided to sponsor systematic research on the progress of humane techniques in the laboratory. [2] In October of that year, William Russell, described as a brilliant young zoologist who happened to be also a psychologist and a classical scholar, and Rex Burch, a microbiologist, were appointed to inaugurate a systematic study of ...
The black-headed gull is a species which aggressively engages intruding predators, such as carrion crows. Classic experiments on this species by Hans Kruuk involved placing hen eggs at intervals from a nesting colony, and recording the percentage of successful predation events as well as the probability of the crow being subjected to mobbing.

Transgenic animal production consists of injecting each construct into 300–350 eggs, typically representing three days' work. Twenty to fifty mice will normally be born from this number of injected eggs. These animals are screened for the presence of the transgene by a polymerase chain reaction genotyping assay. The number of transgenic ...
Some were concerned that Ferrier's experiments would separate God from the mind of man in the name of science. [20] Some of the anti-vivisection movement in England had its roots in Evangelicalism and Quakerism. These religions already had a distrust for science, only intensified by the recent publishing of Darwin's Theory of Evolution in 1859 ...
NORINA's search engine is linked to those of two other databases: TextBase, which provides information on textbooks and other written material of relevance to laboratory animal science and alternatives, and 3R Guide which gives details of guidelines, information centres, databases, journals and email lists within the field of replacement ...
