High Quality Content by WIKIPEDIA articles! A hybrid zone exists where the ranges of two interbreeding species meet. For a hybrid zone to be stable, the offspring produced by the cross have to be less fit than members of the parent species, although this condition does not need to be met in the very first hybrid generation. Some hybrid zones move, typically at a rate of 0.1-10 metres per year. Hybrid zones are relatively rare, although a surprising number are now known to science. They present a problem to the taxonomy of the species involved, and the definition of species more generally. They...
High Quality Content by WIKIPEDIA articles! A hybrid zone exists where the ranges of two interbreeding species meet. For a hybrid zone to be stable, the offspring produced by the cross have to be less fit than members of the parent species, although this condition does not need to be met in the very first hybrid generation. Some hybrid zones move, typically at a rate of 0.1-10 metres per year. Hybrid zones are relatively rare, although a surprising number are now known to science. They present a problem to the taxonomy of the species involved, and the definition of species more generally. They are also important study systems for understanding how new species form, as they are believed to be in transition to reproductive isolation. These zones are often mapped including the current range of both species, with the overlap ranges highlighted. Hybrid zones are locations where the hybrid offspring of two divergent populations are prevalent and form a cline.
