Modern Synthetic Theory of Evolution/Neo-Darwinism

Neo-Darwinism is the term popularly used, even today, for the synthesis between Darwin's theory of evolution by natural selection and the assumption that the variations on which selection acts are produced solely or primarily by gene mutations, though the term Modern Synthesis is more correct since Romanes coined the term neo-Darwinism before Mendel's work on genetics was rediscovered. The Modern Synthesis adds discrete (Mendelian) inheritance to neo-Darwinism.
