Affinity (taxonomy) – mainly in life sciences or natural history – refers to resemblance suggesting a common descent, phylogenetic relationship, or type. [1] The term does, however, have broader application, such as in geology (for example, in descriptive and theoretical works [2] [3]), and similarly in astronomy (for example, see "Centaur object" in the context of 2060 Chiron's close ...
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
3' untranslated region (3'-UTR). Also three-prime untranslated region, 3' non-translated region (3'-NTR), and trailer sequence.. 3'-end. Also three-prime end.. One of two ends of a single linear strand of DNA or RNA, specifically the end at which the chain of nucleotides terminates at the third carbon atom in the furanose ring of deoxyribose or ribose (i.e. the terminus at which the 3' carbon ...
Pierre Belon systematically compared the skeletons of birds and humans in his Book of Birds (1555) [1]. Homology was noticed by Aristotle (c. 350 BC), [1] and was explicitly analysed by Pierre Belon in his 1555 Book of Birds, where he systematically compared the skeletons of birds and humans.
Factors such as mutations, genetic divergence, and hybridization all are considered evolutionary units. [1] With the specific branches, researchers are able to determine the applications and uses for modern-day systematics. These applications include: Studying the diversity of organisms and the differentiation between extinct and living creatures.
