Question

Quizplus · Accepted Answer

The most revolutionary aspect of Darwin's theory was the notion of natural selection as the mechanism for evolution. While the idea of evolution itself was not entirely new, Darwin's proposed mechanism for how it occurred was groundbreaking. The idea of inheritance of acquired characteristics had also been proposed before by Lamarck, but it was not a part of Darwin's theory. Therefore, option D is incorrect as "all of the above" includes the notion of inheritance of acquired characteristics, which was not a part of Darwin's theory.
