Editing Interactor (section)

== Definition ==
Interactor is a concept commonly used in the field of [[evolutionary biology]]. A widely accepted [[Evolution|theory of evolution]] is the theory from [[Charles Darwin]]. He states, in short, that in a [[population]] there is often variation in heritable traits among individuals, in which a form of the trait might be more beneficial than the other form(s). Due to this difference, the chance of getting more adjusted offspring to the environment is higher.<ref>[[On the Origin of Species#Content]]</ref> The process describing the selection of the environment on the traits of organisms is called [[natural selection]]. Based on this idea natural selection seems to act on traits of individuals, which evolutionary biologist like to call the interactor. So stated in a different way; an interactor is defined as a part of an [[organism]] that natural selection acts upon.
