continuously both in time and space, so that ecotypes or forms may qualify as distinct species in a few generations. Begon, Townsend, and Harper offer the following analogy:

Thus ecotypes and morphs can be thought of as precursory steps of potential speciation.

Range and distribution

Research indicates that sometimes ecotypes manifest when separated by great geographical distances as a result of genetic drift that may lead to significant genetic differences and hence variation. Ecotypes
