I had a disagreement with some other posters about this subject on another thread some time ago, and wandered off to search the internet for more information, then couldn’t remember what thread the subject was mentioned in!
I think most people make the mistake of anthropomorphizing the actions of animals. I also hang out on a couple of ethology lists, and have heard several professional behaviorists complain about others using such human-associated, emotionally-laden terms as ‘prostitution’, ‘rape’, and ‘coercive sex’ in reference to animal behavior.
One factor that should be taken into consideration is that, to the best of my knowledge, humans are the only animal with a hidden estrous. All other female animals signal their readiness to mate by odor, physical changes, behavioral changes, etc. Females rarely have much of a voice in which males they mate with - their hormones are demanding copulation, and they will usually mate with whatever male is available and willing at the time. However, normal mating behavior often involves the ‘domination’ of the female by the male, possibly to prove his fitness as a mate. The violence of these encounters may certainly appear to be ‘rape’, but consideration must be given to fact that the female is basically ‘willing’ when she is in estrus.
Since male animals are capable of easily detecting when a female is in estrus and therefore physically ready for impregnation, the idea of rape in animals as a reproductive tactic is ridiculous. Why risk injury from an angry, unwilling female when you KNOW you are wasting your sperm? Just hang around until she comes into heat, and breed her as soon as she is receptive! I would really like to see some evidence from anyone that shows a male animal ‘raping’ a female that is not in estrus, as I’ve not been able to find any examples of such behavior.
This leaves sexual pleasure as the only motivation for ‘rape’ in animals, and again I believe we see a great deal of anthropomorphizing in this area. While the act is undoubtedly pleasurable to at least some degree in most animals, we have no way of knowing how intense this ‘pleasure’ is - it may simply be equivalent to the scratching of an itch. It seems to me that if the desire for the pleasures of copulation in animals was strong enough to drive the males to rape, then animal rape would be the norm and seen on a daily basis. After all, animals don’t have the moral inhibitions of humans - why shouldn’t the males just rape any female in reach whenever they feel like it?
But anyone who has spent any time observing animals can see that this doesn’t happen at all. Look at the behavior of any herd or pack animals - one dominant male breeds teh receptive females, while the junior males hang around the fringes and watch the action. The junior males must be terribly sexually frustrated by this - why aren’t they taking advantage of the senior male’s preoccupation with mating to attack and rape the non-receptive female members of the herd/pack?
Which brings me to my next point - just how the hell does one animal ‘rape’ another? They don’t have guns or knives, and beating the female senseless is certainly not much of an option, especially when the unwilling female is equivalent in size and weaponry. How does a 1500 pound stallion force a 1500 pound mare to stand still while he mounts and rapes her? He’s more likely to get kicked in the belly or genitals and severely injured.
However, it also makes sense that rape IS a viable reproductive tactic in a species such as humans that has a hidden estrous. Since the male has no way of knowing whether or not a female has, or is ready to, ovulate and is therefore receptive to impregnation, forcing copulation with any female available may be worthwhile, based on the chance that he MIGHT impregnate her and therefore pass on his genes.
I found mention of a book due to be published in April 2000 by MIT Press called “A Natural History of Rape: Biological Basis of Sexual Coercion”, by R. Thornhill and C. T. Palmer. Any chance these were the same scientists seen on TV discussing this? I very much want to read this book when it is published. I’ve been around animals all of my life, grew up on a farm, raised cows, dogs, chickens, etc., have worked in a vet clinic for years and am currently attending vet tech school, and have been breeding and raising pedigreed cats for years, and in my experience the whole ‘animal rape’ thing is a load of hooey.
