Rensch, Bernhard (Carl Emmanuel) (Germany 1900-1990)
evolutionary biology, systematics

One of the main architects of the Neo-Darwinian Synthesis, Bernhard Rensch held a position in twentieth century German biology not unlike that his contemporary Ernst Mayr did in the United States: both men were primarily ornithologists by training, both were centrally interested in evolutionary theory, and both took the philosophy of systematics--and science in general--quite seriously. Rensch's early studies concentrated on the zoogeographical characteristics of speciation, finding in the geographic range patterns of polytypic and incipient species clues that shed light on how climate and other factors influenced evolution. He became a pioneer in the use of allometric methods, analyzing Bergmann's rule and working out and naming Allen's and Gloger's rules. Rensch then looked into whether such forces could explain the origin of the more general taxonomic levels, the results of which study are related in his book Neuere Probleme der Abstammungslehre: Die Transspezifische Evolution, one of the primary documents of the Neo-Darwinian synthesis. Rensch's studies touched on many additional subjects; he became especially interested, however, in the relation of animal behavior to physiology and morphology and published work on learning and memory, the brain, sensory physiology, and ethology (which he referred to as "animal psychology").
