You have given me an excellent chance to make my point by posing a wonderfully dishonest question.
You start out by saying “A man and a woman are required for human sexual reproduction.”
Fine, so far, but then you commit the logical fallacy of “the old switcheroo”: “What was the evolutionary stop just before sexual reproduction evolved?”
WHOA!
What happened to the human part? So I’ll fix it for you: “What was the evolutionary stop just before human sexual reproduction evolved?”
This HONEST question can be easily answered: “There is none. The human species have always reproduced sexually.”
Or, the question could be honestly posed in an alternative way, like this: “A male and a female are required for sexual reproduction. What was the evolutionary stop just before sexual reproduction evolved?”
In this case, the answer would be “asexual reproduction”. However, let it be said, that there are species that can reproduce either way. It isn’t necessarily a one or the other situation.
“In this case, the answer would be “asexual reproduction.””
So was there some point in the evolutionary process that asexual reproduction converted to sexual reproduction? Based on the basic hypothesis of evolution (minute changes over billions of years), there must have been. If so, exactly how did the conversion from asexual to sexual reproduction take place?

Is it not really clear that the second sentence is a continuation of the first one? I believe most people would understand that. However, in order to make sure there is no question, I added “human” to the second sentence.
So, my question still stands: How exactly did (assumedly human) asexual reproduction turn into human (male and female) sexual reproduction? Do you really believe that at some point a man and a woman magically appeared through evolution, having the correct sexual characteristics to procreate? Please - use your imagination and give me a credible, believable scenario of how that could have happened.
