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.
16 Σεπ 2013 · 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 is the use of a trait for a different function than it evolved for. Learn about exaptation in various fields of biology, such as molecular biology, plant science, ecology, and urban evolution.
10 Ιουλ 2020 · We identify distinctive patterns of exaptation and expose specific examples of papers that display those patterns. Our approach represents a first step towards the quantification of exaptation phenomena in the context of scientific evolution.
15 Οκτ 2009 · Exaptation is when a feature that evolved for one purpose is later co-opted for another. Learn about the concept, its history, and some examples from plants, animals, and humans.
11 Ιουν 2013 · The term exaptation was introduced to challenge the primacy of adaptation in biological evolution, but has not been widely used in biology. The authors propose a revised definition of exaptation and compare it with adaptation in the context of genetic and cultural evolution.
1 Σεπ 2013 · The term exaptation was introduced to encourage biologists to consider alternatives to adaptation to explain the origins of traits. Here, we discuss why exaptation has proved more successful in technological than biological contexts, and propose a revised definition of exaptation applicable to both genetic and cultural evolution.
