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.
Nature is a leading science journal publishing peer-reviewed research and fostering groundbreaking discoveries for global thought-leaders and decision-makers.
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 …
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.
Adaptation — a feature produced by natural selection for its current function (such as echolocation in bats, right). Exaptation — a feature that performs a function but that was not produced by natural …
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.
Exaptation, a key concept in evolutionary biology, refers to the repurposing of existing traits for new functions. This process plays a significant role in both biological and cultural innovation, …
EXAPTATION definition: a process in which a feature acquires a function that was not acquired through natural selection. See examples of exaptation used in a sentence.
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 — 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 …
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 …
The term “exaptation” was coined to describe acquisition, or “cooption” of a new function with a positive effect on fitness.
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, 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 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.
The meaning of EXAPTATION is a trait, feature, or structure of an organism or taxonomic group that takes on a function when none previously existed or that differs from its original function which had been derived by evolution; also : the condition or circumstance of possessing one or more such traits, features, or structures. How to use exaptation in a sentence.
An “exaptation” is just one example of a characteristic that evolved, but that isn’t considered an adaptation. Evolutionary biologists Stephen Gould and Elizabeth Vrba proposed vocabulary to let biologists talk about features that are and are not adaptations: Adaptation — a feature produced by natural selection for its current function (such as echolocation in bats, right). Exaptation ...
An exaptation is fundamentally a shift in a trait’s function over evolutionary time. This process involves two distinct stages in the history of a feature. First, the trait exists in an organism, either as an adaptation for an unrelated function or as a byproduct of the evolution of another characteristic (a nonaptation).
Exaptation explains how evolution repurposes existing traits for new functions, from feathers enabling flight to how your brain learned to read.
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.
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.
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.
