Human inbreeding is the act of mating between two closely related people, including relatives, parents, or siblings. It is often associated with consanguinity and incest. Human inbreeding is said to be started 60,000 years ago when a small group of early African tribes settled down in Asia and Europe. As the years go by, people have realized the danger of inbreeding amongst humans 34,000 years ago and developed social norms. However, the practice of inbreeding is still present nowadays despite being recognized as a strong taboo across the world.
Inbreeding in the United States of America is legal in 19 states, allowing first-cousin marriages. About 0.2% of all marriages in America are inbred, or roughly 250,000 Americans. About 70% of inbred families live in desolate areas. Inbreeding is common in the southeast region and more rural states, such as Eastern Kentucky.
