Evolution, the modern synthesis. A cornerstone of early neo-Darwinian thought was August Weismann's theory of the germ plasm, which proposed a segregation between germinal and somatic cells during development, thus ruling out the possibility that acquired characters could be inherited. Weismann proposed the theory of the continuity of germ-plasm, a theory of heredity.

Somatic cells (of the body) develop afresh in each generation from the germ plasm.
