From the pathology of love page, I paste

Moreover, we are attracted to people with the same genetic makeup and smell (pheromones) of our parents. Dr Martha McClintock of the University of Chicago studied feminine attraction to sweaty T-shirts formerly worn by males. The closer the smell resembled her father's, the more attracted and aroused the woman became. Falling in love is, therefore, an exercise in proxy incest and a vindication of Freud's much-maligned Oedipus and Electra complexes.

Writing in the February 2004 issue of the journal NeuroImage, Andreas Bartels of University College London's Wellcome Department of Imaging Neuroscience described identical reactions in the brains of young mothers looking at their babies and in the brains of people looking at their lovers.

"Both romantic and maternal love are highly rewarding experiences that are linked to the perpetuation of the species, and consequently have a closely linked biological function of crucial evolutionary importance" - he told Reuters.

This incestuous backdrop of love was further demonstrated by psychologist David Perrett of the University of St Andrews in Scotland. The subjects in his experiments preferred their own faces - in other words, the composite of their two parents - when computer-morphed into the opposite sex.
