Rape would increase reproduction so why have they evolved to prevent it?

AnTiFreeze3 said:Evolution occurs in part due to non-random mating, so I would assume that females evolved to prevent reproducing with just any male, so that way they can selectively choose with whom they mate.

So you're saying that because females resist rape, increasingly complex vaginas would somehow be favored in evolution? I don't see that connection.
Not exactly what I had expected. Interesting.Turion said:

The female duck with no say in chosing her partner will have less fit offspring than the choicy one.Turion said:Suppose two female ducks are born and that they only can give birth to female ducks. Now suppose that one has the power to mate only with the male she wants to mate with. The other doesn't.
The one that can choose her mates might be more selective and only reproduce with one mate. She passes her genes and so the offspring also can choose her mates.
The other might reproduce more due to rape and would have 3 offsprings that cannot choose their mates.
The problem is that females ducks all attempt to prevent rape.

Also, it seems like rape is a good gene to have. So why haven't the males for all species convergently evolved to rape?
Until you get to humans. Motives change when you're not governed by only genetics.bobze said:Your children really only count if they get a shot to grow up and reproduce as well. Females are choosy for this reason.

This is a commonly asked question because duck mating is often portrayed as aggressive and non-consensual. However, female ducks have evolved mechanisms to prevent rape in order to ensure the survival of their offspring.
Female ducks have evolved several physical and behavioral adaptations to prevent rape. These include complex genitalia that make forced copulation difficult, vocalizations to attract other males for protection, and the ability to control the release of their eggs.
By preventing rape, female ducks are able to choose the best and healthiest mates to ensure the survival of their offspring. They are also able to avoid potential injuries and infections that can result from forced copulation.
While preventing rape can have many benefits for female ducks, there are some potential negative effects. For example, the complex genitalia of female ducks can make it difficult for them to mate with desired partners, and they may also experience higher levels of stress and energy expenditure due to the constant threat of rape.
No, not all duck species have evolved these anti-rape adaptations. Some species, like the mallard duck, have relatively simple genitalia and do not have the same level of control over their reproduction as other species. This highlights the diversity and complexity of reproductive strategies in the animal kingdom.
