To be totally frank, my experience with material produced by Harun Yahya (a noted holocaust denier
Talk Reason: arguments against creationism, intelligent design, and religious apologetics ) has not been good. Granted his holocaust denial does not make his ideas about evolution false, but it does call into question his judgment. His creationist writings, while beautifully produced, are universally bad, relying largely on misdirection and quote mines. In fact in Yahya's magnum opus, Atlas of Creation, he uses a picture of a fishing lure as evidence that insects have not evolved.

I do not think that Yahya is a good source of information.
