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. A similar urban shift is happening across the globe. During the past two centuries, the researchers point out, the average relatedness of Icelandic couples has widened from third and fourth cousins to the more recent couple relatedness of fifth cousins.

Children of siblings are cousins. Children of first cousins are second cousins, and their children are third cousins. The results make sense from a biological perspective.

Commonly ” cousin ” refers to a “first cousin”, a relative whose most recent common ancestor with the subject is a grandparent. Degrees and removals are used to more precisely describe the relationship between cousins. Degree measures the separation, in generations, from the most recent common ancestor to one of the cousins whichever is closest , while removal measures the difference in generations between the cousins themselves.

To illustrate usage, a “second cousin” is a cousin with a degree of two. When the degree is not specified first cousin is assumed. A cousin that is “once removed” is a cousin with one removal. When the removal is not specified no removal is assumed. Various governmental entities have established systems for legal use that can precisely specify kinship with common ancestors any number of generations in the past, for example, in medicine and law, a first cousin is a type of third-degree relative.

People are related with a type of cousin relationship if they share a common ancestor, and are separated from their most recent common ancestor by two or more generations. The degree is the number of generations subsequent to the common ancestor before a parent of one of the cousins is found. This means the degree is the separation of the cousin from the common ancestor less one.

Also, if the cousins are not separated from the common ancestor by the same number of generations, the cousin with the smallest separation is used to determine the degree.

Since each ancestor has two parents one mother and one father , you have a total of 2 n ancestors at level n : two parents, four grandparents, eight great-grandparents, sixteen great-great-grandparents, and so on. In short, your ancestors form a perfect binary tree — simplicity itself. Unlike with ancestors, there is no simple formula for your number of descendants. Rather, you have to count up all of your children, and all of their children, and so on.
