Answer: In modern view, the origin of variation is mutation. Since Darwin stated that variation will occurs in the most useful part and is retained, most people don't use their left hands, if according to Darwin's theory, those left hands should be going to extinct by now.

Darwin just had a general idea about variation, offsprings tends to change in appearance from the parents. But this variation is not in terms of usefulness of the body parts of the parents, it is in terms of Gene mutation of the parents in their offspring.
