Darwin in his famous book "The Origin of Species," wrote "If it could be demonstrated that any complex organ existed which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down." Yes there are such organs. They are the reproductive organs. Darwin assumed in his theory that these organs already existed in the first place. Reproductive organs are quite ‘complex organs’. Since most of you know how the human reproductive organs works, and if we were to follow Darwinian evolution path, let’s see how this might be explained by Darwinian evolution. 1. A mutation causes an ovary to grow inside a human, we now call woman. 2. Few generations later, a mutation causes the testicles to grow inside a human, we now call, man. 3. Few generations later, another mutation causes uterus to be in the woman. By now, the reader has to agree, that these is illogical since there is no 'next generation' without having all the organs listed here plus many other organs, in the first place. So by Darwin’s own words, his theory absolutely breaks down. Q.E.D.

Richard Dawkins in his book “Blind Watchmaker" he only glances the subject of reproduction saying crystals 'reproduces' by as it grows and rejects a non-like crystal. He doesn't explain how complex living organisms could have its reproduction organs by series of steps of mutations. It's because he can't do it. Dawkins says in his other book "Climbing Mount Improbable", one can climb such a mountain by many small steps at a time. We know how complex the reproductive organs are. So the question to Dawkins is 'How can series of mutations can result in having reproductive organs without having reproductive organs to start the series of mutations?' Dawkins violates his own Darwinian evolution logic of series of small steps to get to the top of the mountain since having reproductive organs in the first place is a HUGE JUMP, and NOT a series of small steps.
