WebApr 11, 2024 · The "Modern Synthesis" paradigm of the 1930s and 1940s resulted from integrating Darwin's evolutionary theory based on natural selection with the finding of granular gene heredity. The Modern Synthesis disproved many biological myths, notably Lamarck's notion of acquired character transmission and the mixing concept of inheritance. WebDarwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809-1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
