exaptation (countable and uncountable, plural exaptations) (biology, evolutionary theory) The use of a biological structure or function for a purpose other than that for which it initially evolved.
Exaptation or co-option is a shift in the function of a trait during evolution. For example, a trait can evolve because it served one particular function, but subsequently it may come to serve another. Exaptations …
Note: The word exaptation was proposed by Stephen Jay Gould and Elizabeth Vrba in the 1980s as an alternative to preadaptation, which was felt to imply that such traits, features, or structures were …
Exaptation — a feature that performs a function but that was not produced by natural selection for its current use. Perhaps the feature was produced by natural selection for a function other than the one it …
Exaptation is a concept in evolutionary biology describing a trait that is co-opted for a new function, one for which it was not originally shaped by natural selection. This challenges the simple view …
The brain regions responsible for gesture could have been taken over by those used in speech through an evolutionary process called exaptation, wherein parts of an organism take on different or completely …
An exaptation is a trait that evolved for one purpose but later got recruited for a completely different one. Feathers are the classic example: they evolved for insulation long before any bird used them to fly.
The term “exaptation” was coined to describe acquisition, or “cooption” of a new function with a positive effect on fitness.
Exaptation, also radical repurposing, is the taking of an idea, concept, tool, method, framework, etc., intended to address one thing, and using it to address a different thing, often in another domain. The …
Exaptation is a term used in evolutionary biology to describe a trait that has been co-opted for a use other than the one for which natural selection has built it.
Exaptation refers to considering alternatives to adaptation to explain the origins of traits, and has been more successful in technological than biological contexts.
This is one of the best known cases of exaptation, but we see it again and again with both physical and behavioral traits. A dog licking its owner’s face in greeting is an exaptation of the …
Exaptation or co-option is a shift in the function of a trait during evolution. For example, a trait can evolve because it served one particular function, but subsequently it may come to serve another. Exaptations are common in both anatomy and behaviour. Bird feathers are a classic example.
Note: The word exaptation was proposed by Stephen Jay Gould and Elizabeth Vrba in the 1980s as an alternative to preadaptation, which was felt to imply that such traits, features, or structures were destined for a future function.
Exaptation — a feature that performs a function but that was not produced by natural selection for its current use. Perhaps the feature was produced by natural selection for a function other than the one it currently performs and was then co-opted for its current function.
Exaptation is a concept in evolutionary biology describing a trait that is co-opted for a new function, one for which it was not originally shaped by natural selection. This challenges the simple view that every biological feature must have evolved specifically for its current role.
The brain regions responsible for gesture could have been taken over by those used in speech through an evolutionary process called exaptation, wherein parts of an organism take on different or completely novel roles.
Exaptation, also radical repurposing, is the taking of an idea, concept, tool, method, framework, etc., intended to address one thing, and using it to address a different thing, often in another domain. The term "exaptation" was proposed by Stephen Jay Gould and Elisabeth Vrba in 1982.

Because of the rigors of experimentation and control, it is understood to be more likely to be true than a hypothesis is. In non-scientific use, however, hypothesis and theory are often used interchangeably to mean simply an idea, speculation, or hunch, with theory being the more common choice.
In science, an explanation or model that covers a substantial group of occurrences in nature and has been confirmed by a substantial number of experiments and observations. A theory is more general and better verified than a hypothesis. (See Big Bang theory, evolution, and relativity.)
