Historical influences on Darwin

Although the theory was ultimately dismissed in favor of Darwin’s theory of evolution, his theory was integral for it’s observation of the connection between organisms and the external environment in the evolutionary process. Jean-Baptiste Lamarck is known for his contribution to science as an evolutionary theorist. He was the first individual to attempt to explain the evolutionary process, and although his theory was disproved, his notion of the inheritance of acquired characteristics being influenced by the environment help give Scientist like Darwin the right direction to find their own theories.
