Why does jealousy exist?

Evolutionary behavioral adaptation to try to keep the hunter that provides all your protein near you and away from other hungry females. It better ensures the survival of the progeny you have with that particular male.

Just my guess.

TRUTH! Primal instinct for us is to survive and pass on our genes. The healthier and more "attractive" a mate is, chances are the offspring will also carry both sets of genes down and continue the legacy.

To build on this and take the chance of seeming misogynistic:

Women tend to be more jealous among the sexes because men can drop seed and flee. A woman has the far more taxing task of bearing and caring for the offspring. A female and her offspring would be more successful if she could keep the male close and encouraged him to remain with her. Fending off other females (evolutionary jealousy) and providing that particular male with easy access to sex (not just for procreation) helped to ensure this.

This is of course just theory but I find the ideas behind it fascinating.

I studied evolutionary biology also and it's not misogynistic to discuss those concepts. But, I always remember learning that actually females would group together to help each other with the babies. It was men that had jealousy because they needed to keep other men away from their women because another man could impregnate her and he would never know and would raise another man's baby as his own child. Wasting his resources on some other man's propagation of his genes.

you're all correct and the two explanations are not mutually exclusive

men cooperatively hunted to get protein and fat for the tribe. women gathered other foods, which would include some sources of protein (e.g. insects, birds eggs etc) but mainly carbs and micronutrient rich foods. Each relied on the other - as a community more than as specific individuals, i.e. the idea of one man hunting meat for one woman is not strictly correct, although it may be true for small animals like rabbits and squirrels. bigger animals were hunted by a group of men together then shared with the whole tribe, and larger animals also usually provided more fat (you can't live off of rabbits or squirrels as they don't provide enough fat).......... at the same time men relied on the carbohydrates from gathered food, because hunting did not always succeed and they also needed carbs in their system to be successful at hunting. Food would generally have been shared through the whole tribe, though individual food sharing between couples would have happened as well.

Anyway, back to jealousy and affairs........... men tend to be more jealous of sexual infidelity, because it's very bad from an evolutionary point of view to be cuckolded, however there's a big advantage to being the one whose baby is being raised by another man, which is why cuckoldry has remained and not been removed by natural selection. This is confounded somewhat in a tribal society, in that many modern hunter-gatherer tribes have a collective view of paternity (and you'd expect this to be the case, or even more so, in palaeolithic hunter-gatherer tribes, who may not have even understood the concept of paternity), i.e. all the men in the tribe collectively contribute to the tribe's children, so such jealousies are actually rarer than you'd think (though fights to the death over women do happen in modern hunter-gatherer tribes on occasion) because if you're helping to raise the child of another man in the tribe, then he's also helping to raise your child.... this kind of jealousy became more common after the development of agriculture because planting crops leads to the concept of individual ownership of property, and that leads to the concept of inheritance of property, and then that means it's a lot more important to ensure your kids really are your kids, as opposed to someone else's in the same tribe, whether or not he's raising your child, because the property and cultural knowledge is no longer collectively owned, it's individually owned

on the other hand, women tend to be more jealous of emotional affairs, because what she wants from a man (whether or not he's the father of her children) is someone to provide her with protein and fat, which she needs in large quantities while pregnant or breastfeeding, so she needs that investment either from an individual man or from the men of the tribe collectively. It's probably the case that palaeolithic women would have been more upset if a male partner shared food with another woman than if he had casual sex with her, although she would probably not look kindly on the other either, as sex could be the start of a loving relationship that would involve food sharing, which would ultimately result in her getting fewer resources.

Men would have relied on women as well from an emotional point of view, for example he needs the carbohydrates and micronutrients from food gathered by women, and also it's been know that humans have looked after sick and injured members of the tribe, and evidence for this behaviour goes back nearly 2 million years, so if a man in injured while hunting, it may have been his female partner who looked after him, so he is also dependent on emotional investment from women, so you'd expect some jealousy from men of emotional affairs too.... just less so than sexual infidelity, because this could mean that the child of his woman who he loves and shares his food with isn't actually his. But emotional attachment, food sharing, looking after each other when sick, etc, are all very important to human societies and the importance of this is often underestimated in relation to the importance of providing women with meat to sustain pregnancy and breastfeeding, and the importance of men ensuring that the kids they provide for are really their kids.

If you are such a tomboy, why do you believe these nonsense stereotypes about women? Once again a woman that thinks all women in all of the world are different from her. She is the only good woman in the whole entire world. Not realizing that she is buying into a stereotype that has alienated her from female friendships.
