New research has found that people select mates by smell. People fall into distinct smell-types that appear to be directly related to corresponding types of immune systems. The study found that members of couples tended to NOT be of the same smell-type and thus also to not have the same types of immunities; perhaps because this results in offspring having more diverse immunities.
