"Subtle chemical signals, or pheromones, have long been known to draw pairs together within the same species. In mice, for example, experiments showed that pheromones acted as attractants between males and females who were genetically similar except for a difference in a certain type of immune system gene - the HC (major histocompatibility locus). This pairing gives their offspring an advantage in beating back disease organisms."
So the question is, can humans smell out complimenting partners?
