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.
Define exaptation. exaptation synonyms, exaptation pronunciation, exaptation translation, English dictionary definition of exaptation. n. Biology The utilization of a structure or feature for a function other …
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 …
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.
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 …
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, …
Exaptation is defined as a change in function of a trait that originally evolved for a different purpose, allowing it to serve new adaptive roles without any structural changes. An example is the wing feathers …
Exaptation explains how evolution repurposes existing traits for new functions, from feathers enabling flight to how your brain learned to read.
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 …
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.
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 …
Exaptation refers to considering alternatives to adaptation to explain the origins of traits, and has been more successful in technological than biological contexts.
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.
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.
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 …
A computational study reveals surprising flexibility hidden within metabolic networks, providing new evidence for an evolutionary concept called exaptation. Evolution is littered with examples of ...
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.
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 submissive behavior of a wolf toward another in its pack, but toward a different species.
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.
