A science fiction story goes deep into the topic. . .
If All Men Were Brothers, Would You Let One Marry Your Sister?
https://en.wikipedia.org/wiki/If_All...Your_Sister%3F
An Earthman visits the planet Vexvelt, which is shunned by the rest of the colonized universe for unknown reasons. He finds it a utopian paradise, but then discovers to his shock and horror that incest is actively encouraged there.
. . .
However, modern studies do show that inbreeding does harm, and thus voids the story's arguments.

The Westermarck Effect would point to it being mostly cultural i.e. the people you grow up with and live with cause your brain to desensitize any sexual feelings. This might explain why adopted children of women who are very young and attractive still don't find them arousing even though there's no basis for incest repulsion.

Similarly, genetic brothers/sisters who are separated at birth in foster homes sometimes meet later and fall in love (there was a case about that).

But what do you think? Are you attracted to any family members?
It's just nasty...plain and simple!

Are some people on this thread seriously seeking justification for incest?

Charles Darwin was married to his first cousin, and several of their children were sickly and died young, and several of the surviving children were unable to have children of their own. When he began studying plants he discovered that the healthiest, most robust specimens were crossbred, and the weakest ones were inbred. He realized that his own family was an example of this result in humans, and he was wracked with guilt for the rest of his life.

All I see is people conjecturing varied possibilities for the source of the taboo. Independent thought gives you the creeps, does it?

Some closed societies realize this. My ex was actively recruited by the local Hutterite community to get some "fresh blood".

He declined.

I find it amazing that of all people, Charles Darwin didn't know better.

Interesting point about animals. Will puppy littermates breed, if left to their own devices?

Decades ago in college I did research on the origins of the incest taboo. While there were a few exceptions to this taboo, this taboo is prevalent in most cultures for 1000's of years. What exactly was taboo varied a bit. The wide spread taboo, across time and cultures, suggests it's a biological "instinct" that is expressed and learned and reinforced via culture.

Do you remember whether it delved any deeper....like into prevalence by gender, for instance? To the extent that there may be an instinctive component, I wonder if it is stronger in females than males.

Yes. And no I do not justify such interaction of this abnormality.
With millions of adults to bond with choosing granny or cousin Jeb is not a necessity to entertain.

On a side note as a victim of a family member who violated...I find no 'normal' in that act. Nor did my therapist.

I found my wife's mom hot (I would have hit it) but that's probably out of context of incest.
