The Green-Eyed Monster (no, not Doyle...)

[m31andy]

Quite a while ago, cuvalwen raised the question "what evolutionary advantage has jealousy?", to which I couldn't really answer. But it looks like the question may be laid to rest at last.

Looks like it's a by-product of bonding: 'Cuddle chemical' may create green-eyed monster

ETA: kelemvor just pointed out that what they are actually talking about is envy, not jealousy. I'm blaming the monthly report on this one as my brain is currently mush.

Not quite,it's more to do with rivalry than I've got it and you can't have it. You can be jealous of the person who beat you to a promotion for example or jealous of the time parents spend with a sibling. In both cases you don't have the thing you want. Fearful or wary of being supplanted is a good definition.

Is that necesseraly jealousy or mis-named envy?

The 2 are very close but I think the exact facts determin whether its jealousy or envy. You can have all the time you want with your parents and not actually want any more (No envy of your sibling) but still be jealous of the time they spend with your sibling. The fear is that they become closer to your sibling than to you. Same with the promotion, you may not want your collegue's job, or may even have the same job but still feel jealous because you are now not as important as you were. Both situations could also be envy though, if say you wanted more time with your parents or you did want the promotion your collegue got.
