Brutal stone age tribe in Amazon rain forest

National Geographic spends a month just to film a lost tribe of about 120 people. They are a violent people who mostly die by commiting suicide, and who kill deformed children in the most violent way possible. But they are very fit and very healthy with little or no disease.

I've not watched it yet, but I wonder if they used telephoto lenses or if there was exaggeration involved.
Watch that 'little or no disease' phrase though. A few posters here will say that committing suicide at "old age" is a religious act and therefore a disease.
Very violent? In what ways is this manifested other by killing the deformed? Are those who committ suicide avoiding violence?

Well they don't just mercy kill the deformed. They leave them in the jungle to be mauled to death by jaguars. The suicides are usually done because of depression. There are no people in the village much over the age of 30.

There is discussion of violence in the beginning of the clip as one of the women says she wants to kill one of the white people. There is a discussion of Brazilian law which exempts these people from murder trials. If this woman had run up to the stranger and stabbed him with a poison dart, she would not be punished.

Also they are addicted to hallucinogens, and take them frequently (including children).

There would have to be a huge amount
of inbreeding, which would explain the
deformed kids and the depression. One
man gets two women pregnant and those
offspring have a child. They wouldn't know
not to, like old EU royalty.

Even larger communities of people have known medical problems associated with not enough genetic diversity. The Amish for one, and they aren't exactly a tiny community.

The Amish Community Clinic receives two thirds of its annual operating revenues from a week long auction, an example of Community Medicine.

I think 120 is a very small number though.

Didn't we "discover" a tribe like this in the 1960s and it was a hoax?

Yes, it turned out they were a gang
of illegals in Los Angeles. Their
colorful jackets and speaking Esperanto
fooled everybody.

Yes, and a female staffer at WBAI was enraged that the authorities had given knives to the men rather than to the women.

I think in primitive tribes if you marry your first cousin your parents can't be sisters. Only two brothers or brother and sister.

If you marry your first cousin you know you have one set of grandparents in common, but if your mothers are sisters, then there is a possibility of marrying your half sibling.

That doesn't totally eliminate the possibility of marrying a half sibling, but it does greatly reduce it. You have to rely on social conventions.

Marrying a long line of first cousins is not the safest thing in the world to do, but it is fairly common around the world. The classic inbred European royal was the genetically deformed Charles II, whose death set off the first global war in 1700. But he was descended from three uncle-niece marriages in addition to multiple first cousin marriages. Adding up the contributions from all 14 previous generations, he had the same consanguinity index as someone born from a brother and sister.



https://en.wikipedia.org/wiki/Coefficient_of_relationship#Human_relationships
The fact that he was the son of an uncle niece marriage gave him a relationship coefficient of 25% (the same as if he had been the product of half siblings). but the cumulative effect which takes a while to calculate of all the previous marriages meant his relationship coeefficient was 50% (the same as if he had been the product of full siblings).

But in a tribe of 120 people you could probably have a lot of 2nd and 3rd cousin marriages, as well as 1st cousin marriages. Choosing from people who are 4th or 5th cousins would probably give you a very small or nonexistent selection.

Queen Elizabeth and Prince Phillip are third cousins from Queen Victoria's side, and 2nd cousins once removed from the King of Denmark (King Christian's) family.

Rudy Giuliani's first wife was Regina Peruggi from 1968 to 1982. In those days you could appeal to the Catholic church for an anullment on the grounds that you were second cousins once removed. The Catholic church now permits any marriage of people that are more distantly related than first cousins.
