The stigma attached to first-cousin marriages was supported by early studies into human genetics suggesting that "recessive" versions of a gene (which are not expressed unless there are two of them, one from each parent) are more likely to be expressed in the children of genetically related parents, as well as more likely to be defective.Most states in America have either outlawed or restricted the practice, as has China, Taiwan and both North and South Korea.
In other words, it’s rough, and aside from the act of cannibalism, no single reflex of the hive mind triggers such a deep-seated, troglodytic response as whom we choose to couple with.
Which is funny, you know, because even with all of our proscriptions against incest and such, if you read your Bible you’ll notice that humans started with just one man and one woman, so clearly their children would have had to hook up to propagate our millennia-crossing, evolutionarily dominating species, right?
You and your third-cousin-lover share less than 1 percentage of your DNA. Humans have evolved to be unattracted to people with whom we are closely reared.
Growing up with someone as a relative, especially in close proximity, shuts off the boner part of your brain for them.
Although first-cousin marriages are legal in Britain, there have been calls to ban the practice because of reports that it has resulted in a higher-than-average incidence of birth defects in certain immigrant communities where it is common and culturally acceptable.
However, Professors Paul and Spencer said that the risk of congenital defects is about 2 per cent higher than average for babies born to first-cousin marriages – with the infant mortality about 4.4 per cent higher – which is on a par with the risk to babies born to women over 40.
Often, you have to change your opinions on related issues in order to honor that principle, or you have to throw out the principle and change your mind about the original question. You can't appeal to the Bible; in the Bible, God commands marriages between first cousins.
Instead, advocates of laws against cousin marriage appeal to science.
After doing a little research, we are surprised to find that, in about half of the U. Of course, your question does not concern the legality of your prospective union, but what society will say.
Fact is, that’s why these kinds of things are regulated.
You can't just say the practice in question is icky.
