Couples who are third or fourth cousins tend to have more kids and grandkids than other couples. And though considered somewhat of a cultural taboo, mating between “kissing cousins” makes good biological sense, say scientists. The findings, which come from a recent study of Icelanders, shed light on how relatedness affects reproduction and ultimately the size of families. The researchers suggest marrying third and fourth cousins is so optimal for reproduction because they sort of have the “best of both worlds.

The study also has implications for population growth in a world that’s becoming more and more urbanized. In Iceland, the dramatic demographic shift from a rural society to a highly urbanized one could slow population growth as individuals mingle with a bigger pool of distantly related mates and therefore have fewer kids.

Previous studies have uncovered positive correlations, but the biological data has been clouded by socioeconomic factors such as average marrying age and family size in those populations in which consanguineous marriage is commonplace, such as in India, Pakistan and the Middle East.
