Human Evolution Prohibits Incest

The history of evolution has a simple explanation as to why we find incest repulsive, at least if you believe in Darwinism. Where and how we began, and how we managed to evolve into a superior species are explained in The Origin of Species. Watch Human Evolution Made Easy. Neanderthal, hominid fossils, human remains across different continents reveal evolutionary steps in the human species. The one “fossil” that made little sense was Piltdown Man, a hoax invented in 1913 and solved in 1953 that had some of the science world fooled. The lower mandible of Piltdown’s jaw came from an orangutan and the remainder of the skull was human. A man

named Charles Dawson who discovered the skull, was suspected as the perpetrator of the hoax.   Watch Origin of Species Human evolution proves resistant to incest with good reason: incest results in defective offspring since the bloodline between siblings and parent-child is too close to be safe in producing children. The progeny of incestuous relationships therefore have a higher mortality and sterility rate than normal. However there have been families known to marry siblings to one another. If siblings are raised apart for many years, it is feasible they can be married. The same is true of parent-child marriages (weird). This practice occurred in Ancient times among royal families of Ancient Egypt, Greece and Rome who wished to retain family power and wealth. In Roman Egypt sibling marriage was fairly common and socially accepted. However in the animal world incest occurs quite rarely. Read The Enigma of the Incest Taboo.

 Edward Westermarck developed a theory about how incest came to be a social taboo. He claimed that close contact with a person during childhood created an aversion towards sexual relations between the two family members later in life, stating “ there is an absence of erotic feelings between persons living very closely together from childhood.” From this reasoning Westermarck states that “a natural human aversion towards incest develops into a cultural taboo since it defies social norms “(it’s warped).  Freud capitalized on that one when he came out with the Oedipal concept, suggesting that boys become sexually attracted to their mothers at a certain age unless his unconscious mind quashes that idea and he identifies with his father.  Freud was all about sex. Watch Uncertainty Avoidance

The article The Evolution of Incest Avoidance Mechanisms asks the question “what would be the fate of a mutation that made mothers sexually attractive to sons, in a world where mothers found sons attractive also? ”  A mutation of this type would be the result of a double recessive gene, a recessive gene being the submissive gene compared to a dominant gene. That’s a good thing since a recessive gene is almost always over-ridden by a dominant gene and therefore it is more difficult for a recessive gene to pass onto the next generation. However if such a possibility as sexual attraction to one’s own offspring or one’s sibling can be expressed through a gene and this gene is easily replicated then we get into  (creepy) trouble. Watch science of sex: incest

It would appear that we have nothing to worry about in that area at least as far as nature can help. The human geonome has evolved to create revulsion between two blood-related kin when they are raised together and are aware that they are genetically related. However if the two are raised apart and are ignorant of the fact that there is a blood relation, a sexual attraction, although unlikely, is a remote possibility. It is nature’s ability to create a psychological aversion between blood kin that seldom if ever happens. Even human senses, such as our sense of smell, develop an aversion to kin. Body scent, controlled by the immune system, is very similar between siblings and parent-child.  Nature does whatever it can to prohibit human and animal incest although nature’s goal is not based on social taboos, but rather on the avoidance of genetically damaged, infertile and unhealthy offspring.
