dc.description.abstractRichard Woltereck first described the concept of Reaktionsnorm (norm of reaction) in his 1909 paper 'Weitere experimentelle Untersuchungen uber Art-veranderung, speziell uber das Wesen quantitativer Artunterschiede bei Daphniden' ('Further investigations of type variation, specifically concerning the nature of quantitative differences between varieties of Daphnia'). This concept refers to the ways in which the environment can alter the development of an organism, and its adult characteristics. Woltereck conceived of the Reaktionsnorm as the full range of potentialities latent in a single genotype, evocable by the environmental circumstances of a developing organism. Biologists used variants of Woltereck's concept of Reaktionsnorm, often called the reaction norm or norm of reaction, throughout the twentieth century in attempts to explain how developmental responses to the environment can evolve, and even alter the tempo and direction of evolutionary change.en_US
