Sympatrische Artbildung: theoretische Modelle und empirische Daten
Artbildung und Diversifikation in der adaptiven Radiation von BuntbarschenCharles Darwin recognized that new species can originate in several different kinds of geographic settings, including "allopatry" (from the Greek allos meaning "other" and patra meaning "fatherland"), where novel species arise resulting from geographical isolation and lack of homogenizing gene flow, as well as through "sympatric speciation" (from the Greek sym for "the same"), whereby populations diverge into separate species even in the absence of geographical isolation. However, the feasibility and frequency of the latter mechanism has been hotly debated ever since Darwin. Although theoretical as well as empirical evidence has been put forth regularly since the 1930s, biological assumptions of models and the level of support of empirical evidence in studies reporting on sympatric speciation are still often doubted, and, even today, few cases are widely accepted as bona fide evidence for sympatric speciation. While examples of sympatric speciation are published quite regularly, although rather infrequently, and rules for testing allopatric speciation are well-accepted, those for sympatric speciation remain controversial.
It is necessary to better understand the limitations of empirical work in determining crucial parameters of theoretical models such as the strength of selection in disruptive selection that is deemed necessary for sympatric speciation to occur. There is an obvious need for communication between theoretical and empirical evolutionary biologists interested in speciation.
