No they do not. In the Origin of the Species Darwin argued that evolution was the result of natural selection. A decade later in the Descent of Man, he argued that it was due to sexual selection. It took only ten years for him to need to patch holes in his theory. Practically everything he ever said has been refuted by science and has even been abandoned by his own followers.
Surprisingly, you're kind of right. Much of what he established has been superseded by more recent researchers. However, they still agree with the basic idea, it's his specifics that weren't correct.
