Herbert Spencer Jennings was a zoologist, geneticist, and eugenicist. His research helped demonstrate the link between physical and chemical stimulation and automatic responses in lower orders of animals. Tracy Sonneborn would later write: Jennings was so struck by the continued production of hereditarily diverse clones at conjugation, even after many successive inbreedings, that he undertook to examine the matter mathematically.

dbpprop:abstract
  • Herbert Spencer Jennings was a zoologist, geneticist, and eugenicist. His research helped demonstrate the link between physical and chemical stimulation and automatic responses in lower orders of animals. Tracy Sonneborn would later write: Jennings was so struck by the continued production of hereditarily diverse clones at conjugation, even after many successive inbreedings, that he undertook to examine the matter mathematically. As a result, general formulae for the results of diverse systems of mating were published in a series of papers between 1912 and 1917; these were one of the main seeds from which the whole field of mathematical genetics developed.
  • Herbert Spencer Jennings est un zoologiste et un généticien américain, né le 8 avril 1868 à Tonica (Illinois) et mort le 14 avril 1947 à Santa Monica. Ses recherches sur les coélentérés et les échinodermes sont présentées notamment dans son ouvrage The Behaviour of the Lower Organisms (1906). Il étudie le comportement de protozoaires comme ceux des genres Paramoecium et Amoeba. Il complète les observations de Jacques Loeb (1859-1924). Il s’intéresse également à la question de l’hérédité et fait paraître Life and death, heredity and evolution in unicellular organisms.
