Darwin and Darwinism : DARWIN’S THEORY OF EVOLUTION
We know Charles Darwin for his theory of evolution. However, many of us do not know he was not the first person to propose a theory of evolution. He was not the first naturalist to have proposed a concept of evolution or that species undergo important changes over time. Buffon and other naturalists proposed ideas related to evolution before Darwin.
Darwin’s theory was a selectionist theory of evolution; Lamarck’s was an instructionist theory. Lamarck proposed a mechanism called “the inheritance of acquired characteristics”. He remained unsuccessful at linking his theory to strong scientific evidence. The result was his theory being disapproved scientifically.
