Meet the Whitakers, America’s most famous inbred family. The isolated family lives in Odd, West Virginia. Due to their secretive nature, not much is known about them besides the fact that most probably their many mental and physical defects are caused by extreme inbreeding:[1] <https://www.quora.com/#bfzDg> A report by Discover Magazine <https://www.discovermagazine.com/health/what-scientists-found-after-analyzing-cases-of-inbreeding-in-the-uk> found that inbred offspring suffer from reduced cognitive abilities and lung function and are at greater risk from diseases in general. It also found that inbred children are ‘at a high risk of rare recessive genetic disorders. The phenomenon of inbreeding is not an uncommon fact in that part of West Virginia, alas. Many other cases are known throughout history, in particular in royal families such as the Hapsburg family, which went entirely extinct in the 18th century due to its infamous inbreeding.[2] <https://www.quora.com/#VSmIR> (Charles II of Spain, showing the notorious “Hapsburg chin.”) Other, even more famous example: Tutankhanum:[3] <https://www.quora.com/#aXOYB> (…) he could barely walk. Because of necrosis (death tissue) in his left foot, he had to help himself with a cane. Archaeologists found over one hundred walking canes in his tomb. Molecular genetics and computed tomography (CT) scanning of his mummy revealed that he had weak bones and a frail immune system. Although he had all the power, he didn’t enjoy it much. He died of natural causes at the young age of eighteen. (Underneath the mask, we see a different boy.) Now you might think that inbreeding is okay in case of nonhuman animals, but it is actually as problematic as in the case of humans. One famous example are the wolves on Isle Royale, Lake Superior, Michigan (US). Of its wolf population, only two are left — a male and a female. Their relationship is so close that scientists have “no words to describe it,” even more inbred than the historical human examples above:[4] <https://www.quora.com/#fwqhJ> They are father and daughter as well as half siblings, born 2 years apart to the same mother. There once was a strange, abnormal-looking pup of this couple, but it has vanished at some point in time. In general, inbreeding leads to genetic defects in both nonhuman animals and animals. So next time you plan to sleep with your sister, dear reader, at least use some form of birth control.
