The team found feeling jealous could actually be an evolutionary advantage, and we may have inherited it from our ancestors because it helps us protect resources such as our homes and children.
While previous studies have focused on sex differences in jealousy, the researchers set out to assess whether men and women differ when it comes to jealousy of their spouse's opposite-sex friends.
In their study, published in Evolutionary Behavioral Sciences, the researchers, led by Alyssa Sucrese, wrote: 'Past research in evolutionary psychology has proposed, and found evidence of, sex differences in the adaptive functions of jealousy.
