The reference to the by-product quote I am not sure about. Is that a direct quote? I can assure you that Thornill most adamantly does NOT believe rape is simply a by-product but exhibits all the signs of an adaptation.
Yeah, direct quote from Randy Thornhill in an interview a couple years after the paper was published. From Straw men and fairy tales: Evaluating reactions to A Natural History of Rape. It might be a pet idea of his (all scientists have ideas on how things work) but even he has to concede that he didnt find evidence supporting rape-adaptation.
Parsimonious said:
Lets first address your response to there being physical adaptation. There is absolutely no reason to think that having a psychological or behavioral adaptation has to correspond to having a physical adaptation. Why does this have to be the case?
Well there is some reason to think so. In different species psychological selection has had physical selection directly tied in with it or tied in as a byproduct. Hyenas are an example of the byproduct scenario. The aggressive behavior is accompanied by pseudo-penises and other testosterone associated products. There are just several mechanical mechanisms in other organisms that ensure efficient delivery of the goods. Im just saying that I expect to see some mechanism of the same persuasion.

In addition I think it would be very helpful if you say how you would define an adaptation. How you would look to tell the difference between by-products, spandrels, exaptations, ect. The approach that Evolutionary Psychology uses, as well as a great deal of evolutionary biology is the approach of functional design. Adaptations are the result of direct selection and the only evolutionary mechanism that can develop function design is direct selection. Do you agree with this approach or not? I think that might be helpful to get straight.
I agree with the definition.
Parsimonious said:
The functional design is specifically related to the consequences of rape. This design and specificity is strong evidence for adaptation against rape. If women have specific adaptations against rape it means that rape was consistent enough to be a cause of selection.
I didnt pick this out from the papers.

This is only half the evidence to work with. There is the direct evidence of the analysis of men.
Havent seen evidence for it.
Parsimonious said:
And perhaps a more holistic question to ask is do you believe humans have context specific psychological and behavioral adaptations at all?
Hard to say. I think that general responses are prevalent, but I cant rule out the context specific ones either. I just havent seen a context specific reaction paper.
Parsimonious said:
Under these conditions rape as a CONTIGENT plan could evolve.
The contingent circumstances would have to happen very frequently for this to occur. Usually only one method of procreation is ever selected for in a population (the most advantageous)
Yes, actually, personally only in the orangutan and scorpion fly, but there are many documented cases of rape in animals. But the OP specifically asked us not to go to far down this route. But cross-species comparisons of rape and rape behavior can be very interesting and informative when analyzing human rape behavior.
There is a psychological factor involved in rape no present in other organisms, lets try and stick to humans as much as we can.

In the animal kingdom the goal is get your sperm into a female. Male animals will do this in whatever way possible. If a female is unwilling she'll either get away, fight it off, or get "raped." It has nothing to do with evolution or creation.
Well it actually does matter, it may or may not be a method of selection. Hopefully well get some references from research done on the topic and find out.

Rape is disadvantageous to women but that says NOTHING about its advantage to men.
On a final note, going along with my idea that I would expect to see a physical change, selection on just males would have to be quite prominent to not effect female selection. This would also further support my idea that selecting for male adaptations would include some physical traits. But then again I might be wrong, I just havent seen the support for this view.
