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 ...
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. [3]
In biology, evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Biological populations evolve through genetic changes that correspond to changes in the organisms ' observable traits .
For example, Latin habēre and German haben both mean 'to have' and are phonetically similar. However, the words evolved from different Proto-Indo-European (PIE) roots: haben, like English have, comes from PIE *kh₂pyé-'to grasp', and has the Latin cognate capere 'to seize, grasp, capture'.

Etymology (/ ˌ ɛ t ɪ ˈ m ɒ l ə dʒ i /, ET-im-OL-ə-jee [1]) is the study of the origin and evolution of words, including their constituent units of sound and meaning, across time. [2] In the 21st century a subfield within linguistics, etymology has become a more rigorously scientific study. [1]
The word "pressed" connotes a certain weight put on someone. It could mean being upset or stressed to the point that something lives in your mind "rent-free," as Black Twitter might say. Or, in ...
Carcinisation (American English: carcinization) is a form of convergent evolution in which non-crab crustaceans evolve a crab-like body plan. The term was introduced into evolutionary biology by L. A. Borradaile, who described it as "the many attempts of Nature to evolve a crab". [2]
