- n. Darwinism as modified by the findings of modern genetics.
Century Dictionary and Cyclopedia
- n. New or modified Darwinism; specifically, the doctrine or opinion that the survival of the fittest, in the struggle for existence, is an all-sufficient account of the origin of species, as contrasted with Darwin's opinion that natural selection is an important, but not the exclusive means of modification. Since Weismann is the latest of its prominent advocates it is commonly regarded as identical with Weismannism, although many neo-Darwinians reject the system of metaphysical subtilties that makes up Weismann's doctrine of germ-plasm. See
Weismannism .
GNU Webster's 1913
- n. The theory which holds natural selection, as explained by Darwin, to be the chief factor in the evolution of plants and animals, and denies the inheritance of acquired characters; -- esp. opposed to
