| Description | Ernst Mayr's main expertise lay in ornithology and the geographic distribution of bird species in the world. Two of his most important books are “Systematics and the Origin of Species” and, in particular, “Animal Species and Evolution”. Mayr reviewed the history of development of species concepts in systematics. Species definitions had been based on morphological criteria since Carolus Linnaeus's “Systema Naturae”. Every newly-collected individual organism that differed from others in some characteristic was marked as a “type” of a new species. Mayr argued that a species is a populational unit, composed of local populations of individuals which exchange genes freely among themselves, but not with populations belonging to other species. He considered that the issue of speciation deserves more attention, since there is no agreement among scientists about the genetic context of speciation. Contrary to common thought, geographical clines are not conducive to speciation. Book Name: Milestones in the Evolving Theory of Evolution |
