……………She has presented her posterior and he tries to respond. However, her newly arranged and pneumatic body (“…as the female primate changed into the female human, her new body made sex difficult. Her vagina was now not easily accessible but difficult to get to. It moved far forward, got a covering layer of flesh, and became hidden between two heavy columns of bone and muscle.”) prevents his success. Now, what happens if some bright boy comes up with a flash of brilliance: “If I can’t reach from this side, how about if I try from the other?” Carrying out his brilliant plan, he flips her on her back, spreads her legs, and tries again.

This is fine for him. However, what is her reaction? Remember, up to this time, all mating has been from the rear. For him to flip her on her back and get on top of her must mean, to her, that he is attacking, not mating. On her back her soft belly is unprotected, she can’t run, her legs are unavailable since he’s between them. In other words, she’s scared out of her little protohuman mind.

She has two choices: fight back, or submit. If she fights back, he fights as well. Since he is probably bigger and stronger, if only slightly, he will probably win. She will thus fall back on choice two — she submits and makes appeasement signals.

Now is when things get weird. She submits, making appropriate appeasement signals. He, following instinct triggered by her signals, immediately stops what he is doing and backs away. It doesn’t matter that he wasn’t actually attacking. What does matter is she made appeasement signals and he must back away.

She, of course, is bewildered. She was all set for the undoubtedly enjoyable activity of sex. Suddenly, he attacks her. What’s the matter with him?

He’s even more confused. She came up obviously prepared for fun. He was of like mind. However, he has difficulties because of her changed anatomy that he hasn’t adapted to yet. He came up with the perfect solution, and she immediately tried to fight him off. What’s the matter with her? Then, when she stopped fighting, he instantly lost interest. What’s the matter with him? What’s the matter with this whole business?

However, this was the story of Mr. A. What about Mr. B? Same scenario, but when she makes appeasement signals, Mr. B reacts. However, unlike Mr. A, he does not back off, but continues until orgasm. Why? His instinctual reaction to appeasement signals is weak; they do not instantly turn off his actions. The upshot is Mr. A and his genes die out; Mr. B and his genes continue. Enough Mr. Bs and the instinct for stopping aggressive behavior when opponents surrender is bred out of the species. Aggression is bred into sex.
