"Modern evolutionary synthesis From Wikipedia , the free encyclopedia Â• Learn more about using Wikipedia for research Â• Jump to : navigation , search The modern evolutionary synthesis refers to a set of ideas from several biological specialities that were brought together to form a unified theory of evolution accepted by the great majority of working biologists . This synthesis was produced over a period of about a decade ( 1936-1947 ) and was closely connected with the development from 1918 to 1932 of the discipline of population genetics , which integrated the theory of natural selection with Mendelian genetics . Julian Huxley invented the term , when he summarised the ideas in his book , Evolution : The Modern Synthesis in 1942 . Though the 'Modern Synthesis ' is the basis of current evolutionary thinking , it refers to a historical event that took place in the 1930s and 1940s . Major figures in the development of the modern synthesis include R. A. Fisher , Theodosius Dobzhansky , J.B.S . Haldane , Sewall Wright , Julian Huxley , Ernst Mayr , Bernhard Rensch , George Gaylord Simpson , and G. Ledyard Stebbins . The modern synthesis solved difficulties and confusions caused by the specialisation and poor communication between biologists in the early years of the twentieth century . Discoveries of early geneticists were difficult to reconcile with gradual evolution and the mechanism of natural selection . The synthesis reconciled the two schools of thought , while providing evidence that studies of populations in the field were crucial to evolutionary theory . It drew together ideas from several branches of biology that had become separated , particularly genetics , cytology , systematics , botany , morphology , ecology and paleontology ."
