Scientists in Iceland have discovered that the secret to high fertility levels may lie in family genes. Biologically speaking, partnering with someone who is a second, third or in some cases first cousin can lead to a higher birth rate. According to scientist Kari Stefansson of the University of Iceland, a species is "a group of individuals who are closely enough related to each other to be able to have offspring". By that definition, we have to be related to have kids, albeit only distantly. Staying closer, it seems, improves the odds for fertility.
Further probing into the article reveals that procreating with a cousin can be a double-edged sword. On the one hand, the mother and the fetus have a better chance of genetic compatibility, reducing the risk of Rh incompatibility, a condition that is deadly to a fetus. On the flip-side, the chances for the child inheriting genetic defects is higher, since both parents may posses the genetic markers for the same defect.

As the article points out, marrying a cousin can be marred by social norms. Although science suggests that it can be a healthy practice, only 26 states allow it. What I've never understood is why, when modern science tells us we may be wrong on certain notions, we insist on sticking to our archaic values.
Scientists are suggesting we start marrying our siblings, although step-siblings have been known to marry before. Too often are we afraid to accept new ideas. Why does marrying a cousin even sound like its taboo? Because our forefathers said it was? Society is far to willing to accept something on blind faith. In order to evolve as a species, we have to open our minds to new ideas. No matter how crazy they sound.
