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." While first-cousin couples could have inbreeding problems, couples who are far-removed from each other could have genetic incompatibilities.

"Our definition of a species is a group of individuals who are closely enough related to each other to be able to have offspring," said lead author Kari Stefansson of the University of Iceland in Reykjavik.At the end of the 18th century, the average age of first marriage was 28 years old for men and 26 years old for women.During the 19th century, the average age fell for English women, but it didn’t drop any lower than 22.In that passage, we are commanded not to marry a parent, a step-parent, a grandchild (and, understood, a grandparent), a sibling, a brother or sister of a parent (i.e., an aunt or uncle), or a half-sibling.Marriage between cousins is nowhere forbidden in the Bible.
