Albert Einstein and his second wife and first cousin , Elsa Einstein, took family marriage to a new level. They were related through both maternal and paternal lineages: Their mothers were sisters and their fathers were first cousins. Yaniv Erlich has a soft spot for genealogy. A data scientist at Columbia University and the chief science of officer of the DNA test company MyHeritage, he describes many things in the context of family.

The paper, published Thursday in the journal Science, looks at genetic data from millions of online genealogy profiles. Among other things, the researchers were able to determine at what point in history marrying your cousin went out of vogue, and the average degree of relation between married couples today. And scientific geniuses like Albert Einstein and Charles Darwin married their cousins, too.
Why You Should Marry Your Third Cousin
But within a century, that had changed. By , married couples were, on average, more like seventh cousins, according to Erlich. One common sense explanation for this shift is that when transportation methods improved, bachelors and bachelorettes had access to potential partners they had once been denied by geography.
This makes sense, given that before , most people stayed in place and ended up marrying someone who lived with in a six-mile radius of where they were born. Other factors could be at play, however.
Erlich says that, according to his data, many continued to marry their cousins even after the Industrial Revolution dramatically improved mobility. While proximity may be one key to romance, it seems consolidating money or power played an important part in family marriages, too. By Emily Chambers Miscellaneous January 25, Who is this Dolly Harling from Smithtown, and why is she so badass?
New Girl employed the same plot device last night when it was discovered that Jess and Robby are third cousins.

Or, to make it blunt, you and your date have a great-great-grandparent in common. Did you feel squicked out? For these non symmetrical relationships the relationship of the person from the most recent generation is displayed i. Cousin marriage is important in several anthropological theories which often differentiate between matriarchal and patriarchal parallel and cross cousins.
Some groups encourage cousin marriage while others attach a strong social stigma to it. In some regions in the Middle East over half of all marriages are between first and second cousins. In other places it is legally prohibited and culturally equivalent to incest. Married couples that possess higher than normal consanguinity , shared identical DNA and genetic material, have an increased chance of sharing genes for recessive traits.
First cousins have four times the consanguinity of second cousins, while first cousins once removed have half that of first cousins. Double first cousins share both sets of grandparents and have twice the degree of consanguinity of ordinary first cousins; genetically, they are as related as half-siblings.
Children of these marriages may have an increased risk of genetic disorders , particularly if their parents both carry a harmful recessive mutation. In a scenario where two monozygotic identical twins mate with another pair of monozygotic twins, the resulting double cousins would test as genetically similar as siblings.
Scientists through multiple studies have established a substantial and consistent positive correlation between the kinship of couples and the number of children and grandchildren they have. The deCODE study results show that couples related at the level of third cousins have the greatest number of offspring, with the greatest reproductive success observed for couples related at the level of third and fourth cousins. The study result was somewhat counterintuitive from an evolutionary perspective because closely related parents have a higher probability of having offspring homozygous for deleterious recessive mutations, although closer parental kinship can also decrease the likelihood of immunological incompatibility between mother and offspring, for example in rhesus factor blood type.
