All of these facts, the types of plants and animals found on oceanic islands, the large number of endemic species found on oceanic islands, and the relationship of such species to those living on the nearest continents, are most easily explained if the islands were colonized by species from nearby continents that evolved into the endemic ...
Understanding Animal Research (UAR) is a British membership organisation formed in late 2008 through the merger of the Research Defence Society and the Coalition for Medical Progress. Its main aims are to "explain why animals are used in medical and scientific research.
Scientific evidence is evidence that serves to either support or counter a scientific theory or hypothesis, [1] although scientists also use evidence in other ways, such as when applying theories to practical problems. [2] Such evidence is expected to be empirical evidence and interpretable in accordance with the scientific method.
Zoology (UK: / z u ˈ ɒ l ə dʒ i / zoo-OL-ə-jee, US: / z oʊ ˈ ɒ l ə dʒ i / zoh-OL-ə-jee) [1] is the scientific study of animals.Its studies include the structure, embryology, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems.
A scientific theory is a well-substantiated explanation of such facts. The facts of evolution come from observational evidence of current processes, from imperfections in organisms recording historical common descent, and from transitions in the fossil record. Theories of evolution provide a provisional explanation for these facts. [1]
Animal body lengths range from 8.5 μm (0.00033 in) to 33.6 m (110 ft). They have complex ecologies and interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology, and the study of animal behaviour is known as ethology.
None of these animals that science suggests are good to keep are actually all that popular among humans.
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.
