isolating mechanism

in evolution, a mechanism that prevents two populations from interbreeding and thus enables the populations to diverge enough to allow separate species to evolve. Isolating mechanisms may also prevent interbreeding between overlapping species. Geographic separation, behavioral differences, differences in physical features, and different seasons for reproduction all serve as isolating mechanisms.
