Definition

Glossary of Evolution (2nd ed.) by Futuyma (2009)

  • A process of genetic change in a population whereby, as a result of natural selection, the average state of a character becomes improved with reference to a specific function, or whereby a population is thought to have become better suited to some feature of its environment. Also, an adaptation: a feature that has become prevalent in a population because of a selective advantage conveyed by that feature in the improvement in some function.

Glossary of Ecology (6th ed.) by Krebs (2009)

  • any alteration in the structure or function of an organism by which the organism becomes better able to survive and multiply in its environment.

Glossary of Plant Systematics (1st ed.) by Simpson (2006)

  • A structure or feature that performs a particular function and which results in increased survival or reproduction.

Glossary of The Cell (5th ed.) by Alberts et al. (2008)

  • (1) adaptation (desensitization): Adjustment of sensitivity following repeated stimulation. The mechanism that allows a cell to react to small changes in stimuli even against a high background level of stimulation. (2) evolutionary adaptation: an evolved trait.

Glossary of "Evolution (3rd ed.)" by Futuyma (2013)

  • A process of genetic change in a population whereby, as a result of natural selection, the average state of a character becomes improved with reference to a specific function, or whereby a population is thought to have become better suited to some feature of its environment. Also, an adaptation: a feature that has become prevalent in a population because of a selective advantage conveyed by that feature in the improvement in some function. A complex concept.

Glossary of "Biology (3rd ed.)" by Hardin & Bajema (1978)

  • the fitness of an organism for its environment; it is usually measured by longevity (physiological adaptation) or by reproductive success (evolutionary adaptation); also, the process leading to the adapted condition.
