Lamarckism Vs Darwinism Research Paper

Free Response #2 Both Lamarckism and Darwinism were theories of evolution rooted in the concept of adaptation and an organisms response to environmental changes, however they differed in the mechanisms of how it happens. Lamarckism is in support of a theory that organisms evolve by acquiring favorable characteristics in response to their environment and directly pass them onto their offspring. In addition, according to Lamarckism, genetic variation occurs in a favorable direction, meaning that evolution is progressive from generation to generation. For example, Lamarckism evolution would argue that if a species lived in an environment that favored hairy coats, animals would perceive this need, grow the coats, and pass it on to their ancestors.
