Weismannism

[waismәnizәm]

Definition

n. the doctrine in biology of August Weismann (born 1834)—that acquired characters are not transmitted function and environment affecting the individual only not the species the sole source of evolutionary change being the intermingling of germ-plasma which occurs in fertilisation and the condition of progress being found in the action of natural selection on the germinal variations which thus arise.
