It's actually the editor who supplied that link. But the quotation from that article seems plausible to me, especially the last part about child-rearing.

The counterview you link to is about whether romantic love is universal. But that counterview takes on a strawman. What's universal is the chemistry of romantic love, the suite of love hormones. What's not universal is the culture of romantic love. In patriarchal societies, marriage is usually an economic transaction because the women are treated as property. Once the pair form a sexual relationship, they often "fall in love" because of the universality of the chemical reactions to the sex act. They bond together to help them raise the offspring.
