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.
4 Μαρ 2022 · Here we suggest that the concepts of adaptation and exaptation are universal, synergistic, and recursive and apply to small molecules such as metabolites, cofactors, and the building blocks of extant polymers.
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 refers to the shifts in functions of a trait during evolution, so that one trait originally serving a particular function may evolve and serve another one, achieving complete fitness for that trait (Gould, 1991; Gould and Lewontin, 1979).
11 Ιουν 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.

10 Ιουλ 2020 · Exaptation is a term coined by Gould to challenge the adaptationist bias of neo-Darwinian evolutionary theory. This chapter reviews the theoretical background, the philosophical critiques and the empirical support of exaptation in light of recent research.
