By Kerry Lotzof. Charles Robert Darwin (1809-1882) transformed the way we understand the natural world with ideas that, in his day, were nothing short of revolutionary. He and his fellow pioneers in the field of biology gave us insight into the fantastic diversity of life on Earth and its origins, including our own as a species.

First, he argues that imperfect or functionless traits are evidence against design. Second, he argues that since special creationism can be made compatible with any observation, it is unscientific and explanatorily vacuous. In later works, Darwin shifts to …Lamarckism. Lamarck argued, as part of his theory of heredity, that a blacksmith 's sons inherit the strong muscles he acquires from his work.

Darwin used the expression "descent with modification" rather than "evolution".
Theory of Lamarck or Lamarckism: This theory defines that the traits acquired by any generation will be inherited by the next generation of the same species.
