I also have this that I just edited. The Treaty of Easton was signed on October 26 of 1758 during the French and Indian war. To make it official, a ceremony was held in Easton, Pennsylvania between the British colonial governors of the regions of Pennsylvania and New Jersey, and representatives of 13 different Native American nations. The treaty specified that the Native American nations would not create alliances with the side of the French against the British in the current war. In return, Pennsylvania returned large blocks of land which the Lenape had lost to them years before. The British colonial governors promised to recognize Lenape and other tribes' rights to their hunting grounds in the Ohio River valley. But, that part of the treaty was clearly broken. By the treaty, the Lenape yielded all remaining claims to land within the Province of New Jersey for the sum of one thousand Spanish dollars.

as university of miami psychologists debra lieberman and adam smith pointed out in a recent article in the journal current directions in psychological science, humans have social and psychological mechanisms to deter incest. with very few exceptions, marriages between brothers and sisters and between parents and their children are verboten in every human culture. the primary psychological anti-incest mechanism is the yuck response. even the idea of sex with their mom or dad, bro or sis is upsetting to most people. the psychologist jonathan haidt has found that nearly everyone is repelled by the prospect of brother-sister sex, even in hypothetical situations in which there is no chance of pregnancy).

the biological cost of incest

this raises an interesting question: just what’s so bad about incest? sure, having sex with your dad or your sister seems gross — but why? some anthropologists have argued that incest taboos are learned social conventions. this explanation, however, doesn’t make sense to me as it does not explain the widespread existence of anti-incest mechanisms in creatures ranging from cockroaches to chimpanzees. second, the incest taboo is about as close to a universal law as human moral rules get.

why should mechanisms to avoid incest be so widespread both in nature and across human societies? the answer is simple. the problem with having sex close with relatives is that there is an astonishingly high chance that your offspring will be born with a serious birth defect.
