On Germinal Selection as a Source of Definite Variation

On Germinal Selection as a Source of Definite Variation, published in the late 19th century by German biologist August Weismann, presents a theory of evolution that expands upon Darwin's principles of natural selection. Weismann argues that variation and adaptation are influenced by germinal elements within organisms rather than solely by external environmental factors. This work is notable for rejecting the inheritance of acquired characteristics, contributing significantly to the discourse on evolutionary biology and the eventual rejection of Lamarckism. Weismann's exploration of heredity and selection mechanisms remains influential in the field today.
