    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 ...

  3. Devolution (biology) - Wikipedia

    en.wikipedia.org/wiki/Devolution_(biology)

    Devolution, de-evolution, or backward evolution (not to be confused with dysgenics) is the notion that species can revert to supposedly more primitive forms over time. The concept relates to the idea that evolution has a divine purpose and is thus progressive (orthogenesis), for example that feet might be better than hooves, or lungs than gills.

  4. Evolvability - Wikipedia

    en.wikipedia.org/wiki/Evolvability

    Evolvability is defined as the capacity of a system for adaptive evolution.Evolvability is the ability of a population of organisms to not merely generate genetic diversity, but to generate adaptive genetic diversity, and thereby evolve through natural selection.

  5. Humans did not evolve from either of the living species of chimpanzees (common chimpanzees and bonobos) or any other living species of apes. [174] Humans and chimpanzees did, however, evolve from a common ancestor. [175] [176] This most recent common ancestor of living humans and chimpanzees would have lived between 5 and 8 million years ago. [177]

  6. Evolution - Wikipedia

    en.wikipedia.org/wiki/Evolution

    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]

  7. Objections to evolution - Wikipedia

    en.wikipedia.org/wiki/Objections_to_evolution

    Objections to evolution have been raised since evolutionary ideas came to prominence in the 19th century. When Charles Darwin published his 1859 book On the Origin of Species, his theory of evolution (the idea that species arose through descent with modification from a single common ancestor in a process driven by natural selection) initially met opposition from scientists with different ...

    A thesaurus (pl.: thesauri or thesauruses), sometimes called a synonym dictionary or dictionary of synonyms, is a reference work which arranges words by their meanings (or in simpler terms, a book where one can find different words with similar meanings to other words), [1] [2] sometimes as a hierarchy of broader and narrower terms, sometimes simply as lists of synonyms and antonyms.
