  2. Experimental evolution - Wikipedia

    en.wikipedia.org/wiki/Experimental_evolution

    Experimental evolution is the use of laboratory experiments or ... Like other experimental research in evolutionary biology during this period, much of this work ...

  3. Evolutionary biology - Wikipedia

    en.wikipedia.org/wiki/Evolutionary_biology

    Evolutionary biology is the subfield of biology that studies the evolutionary processes (natural selection, common descent, speciation) that produced the diversity of life on Earth. It is also defined as the study of the history of life forms on Earth. Evolution holds that all species are related and gradually change over generations. [1]

  4. Outline of evolution - Wikipedia

    en.wikipedia.org/wiki/Outline_of_evolution

    Evolutionary ecology – Interaction of biology and evolution; Evolutionary physiology – Study of evolutionary changes in physiological characteristics; Evolutionary taxonomy – Form of biological classification; Experimental evolution – Use of laboratory and field experiments to explore evolutionary dynamics

  5. Evidence of common descent - Wikipedia

    en.wikipedia.org/wiki/Evidence_of_common_descent

    Experimental evolution uses controlled experiments to test hypotheses and theories of evolution. In one early example, William Dallinger set up an experiment shortly before 1880, subjecting microbes to heat with the aim of forcing adaptive changes. His experiment ran for around seven years, and his published results were acclaimed, but he did ...

  6. Phyletic gradualism - Wikipedia

    en.wikipedia.org/wiki/Phyletic_gradualism

    The word phyletic derives from the Greek φυλετικός phūletikos, which conveys the meaning of a line of descent. [2] Phyletic gradualism contrasts with the theory of punctuated equilibrium, which proposes that most evolution occurs isolated in rare episodes of rapid evolution, when a single species splits into two distinct species, followed by a long period of stasis or non-change.

  7. Introduction to evolution - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_evolution

    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 .

  8. Evolutionary tradeoff - Wikipedia

    en.wikipedia.org/wiki/Evolutionary_tradeoff

    In evolutionary biology, an evolutionary tradeoff is a situation in which evolution cannot advance one part of a biological system without distressing another part of it. In this context, tradeoffs refer to the process through which a trait increases in fitness at the expense of decreased fitness in another trait.

  9. Red Queen hypothesis - Wikipedia

    en.wikipedia.org/wiki/Red_Queen_hypothesis

    A recently observed example has as protagonists M.xanthus (predator) and E.coli (prey) in which a parallel evolution of both species can be observed through genomic and phenotypic modifications, producing in future generations a better adaptation of one of the species that is counteracted by the evolution of the other, thus generating an arms ...
