If same blood sex children didn't born disabled, would most marriages happen within family?

Question

hes it got to do with morals, ethics or just a biological fact determining our way of thinking and whom we ''fall'' for?

Answer 1

Actually, in all truth, 98% of children born to incestuous parentage turn out fine.

Morals or ethics? Not exactly. More like economics. Our marriage customs are defined by economics. Marriage has always been an economic arrangement, going all the way back to ancient civilizations like Greece and Rome where the purpose of marriage was to ensure that property would be passed down to offspring.

That said, incest is a taboo because incestuous marriages don't bring new wealth into a family. It's a common thread of marriage throughout cultures from Europe to India to Asia: You don't marry someone poorer than your own family, and you try to marry someone richer. Those are nearly universal in how different cultures have viewed marriage the same way. It would especially have been true in cultures where families were also businesses (i.e., farming families, where every member works on the family farm). If you marry your brother/sister in that situation, you're not bringing new wealth into the family. If you expand the number of people in your family (such as by marrying outside your family), you increase the overall wealth your family has access to.

The notable exception is European royalty, who regularly practiced incestuous marriage all the way back to ancient Rome. Even then, the reason is the same: You can't marry someone poorer than your own family. If you're royalty, you have to marry other royals. Since most royals belonged to the same bloodline they tended to marry within their own families to protect their socioeconomic status. Not always, but it was certainly very common.

Of course, over time justifications have developed for why this should be: incest is morally wrong and violates religious beliefs, incest produces deformed offspring, etc. But you have to remember, these beliefs were justifications for the economic practicality of marrying outside your own family.

Answer 2

There is a saying ..... familiarity breeds contempt. Marriage is the result of an initial special attraction flowering into love and/or intent to marry. Within family members, this kind of initial attraction does not normally take place.

Another reason is the strong social custom prohibiting such marriage, which in turn must be due to the medical reason of risks of deformed or otherwise unsatisfactory offspring.

However, there are stray social customs whereby marriage of cousins is actually preferred with the aim of retaining family wealth within the family itself.

In jest I may also add that if marriages are made in Heaven, perhaps Heavenly principles forbid marriage between close blood relatives.

Answer 3

if your asserting that a number of the babies born to inbred contributors of the comparable kinfolk, are all of them going to be born O.ok. and the respond isn't any vehemently No, do not even think of it NO. i will take you to a city in Northern Minn. it is one kinfolk, particularly up till 1945 then and, in uncomplicated terms then all of it started spreading yet, some contributors nevertheless insisted on interbreeding, cousins (first cousins) or perhaps sisters, and brothers. total households are mentally disabled six and 7 babies, are developmentally disabled. i offered my eggs from a kinfolk that had 8 childrens that have been from one set of first cousins, it grew to become into like finding at an comparable image and none ought to write their names, some have been of their 1930s. So with this reported, No, comparable kinfolk won't be able to, should not be married.

Answer 4

It is neither morals or biology as the main reason... Biology happens to be a great deterrent....
The very basic nature of man is to expand himself... and he seeks through every possible activity, like the business trying to expand overseas (though it is enough to trade in one's own street to make a living).... marriage is no exception... there is a tremendous joy in 'bonding' with an entirely new type of person, and then 'together' seeking a newer life's experience through the off-springs !

Answer 5

I think morals and ethics go a long way to keep you from banging your sister. However, Biologically, is also a deterrent
Even animals, in the wild, try to keep from interbreeding.
It's just something in our genitic makeup that tells us No.
