adaptive type A population or taxon that has distinctive adaptive attributes, expressed as a particular morphological theme, characteristic of a particular habitat or mode of life. In evolutionary terms, the appearance of a new adaptive type is frequently followed by radiations that yield variants; these partition the environment and exploit it more effectively.
