Adaptation, in biology, the process by which a species becomes fitted to its environment; it is the result of natural selection’s acting upon heritable variation over several generations. Organisms are adapted to their environments in a variety of ways, such as in their structure, physiology, and genetics.

In biology, adaptation is defined a heritable behavioral, morphological, or physiological trait that has evolved through the process of natural selection, and maintains or increases the fitness of an organism under a given set of environmental conditions. This concept is central to ecology: the study of adaptation is the study of the ...
Adaptation is one of the two main processes that explain the observed diversity of species, such as the different species of Darwin's finches. The other process is speciation , in which new species arise, typically through reproductive isolation .
16 cze 2022 · Physiological adaptation (biology definition): a metabolic or physiologic adjustment within the cell, or tissues, of an organism in response to an environmental stimulus resulting in the improved ability of that organism to cope with its changing environment.
19 paź 2023 · In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. Although scientists discussed adaptation prior to the 1800s, it was not until then that Charles Darwin and Alfred Russel Wallace developed the theory of natural selection.
Describe what an adaptation is and how it arises, and explain examples of common adaptations in plants and animals. Compare and contrast some of the broad strategies organisms employ to deal with a variable environment.
20 cze 2018 · An adaptation, or adaptive trait, is a feature produced by DNA or the interaction of the epigenome with the environment. While not all adaptations are totally positive, for an adaptation to persist in a population it must increase fitness or reproductive success.
