Bernhard Rensch was born January 21, 1900 in Thale, Germany and died on April 4, 1990 in Munster, Germany. Rensch was a German evolutionary biologist and an ornithologist. In 1927 he took part in expedition to the Lesser Sunda Islands and then to India. He was one of the main architects for the neo-darwinian synthesis, which is a theory of evolution of natural synthesis, and he also believed that geographic isolation, which is a term used when species are isolated from one another to an extent that prevents or interferes with genetic interchange, of a species is key part in evolution. Organisms set clear conditions on evolution and set ways to deal with location problems. When a species goes through a significant amount of evolution with Taxon, the previous stage of the species usually dies out and the new stage comes into the world. When he completed his expeditions and analysis of his data, he found connections in three major fields: the area of evolutionary theory, the trans-specific evolution of animal psychology, and biophilosophy. Rensch's rule was proposed in 1950, which stated that this law "is an allometric law about the relationship between sexual size dimorphism and which sex is larger. It observes that across species size dimorphism increases with increasing body size when the male is the larger sex, and decreases with increasing average body size when the female is the larger sex". In other words, living things of a certain species of the smaller veriety correlate with the larger variety. Rensch's rule is used in modern science to help determine evolution.
