Synthetic theory of evolution

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.
