Was there ever a point in time where a human society didn't know how pregnancy was caused? Given the huge delay between sex and actual signs of pregnancy?

[Anonymous No.4390132]

This is actually an interesting question. Bump.

Right now, in several places around the world. Notably Africa.

Oddly enough, he was likely asexual.

The Christian kid in my 7th grade class didn't know sex was necessary for procreation.

[Anonymous No.4390181]

Huge delay?

If a girl doesn't have her first period and has sex she won't get pregnant. If she has her period and has sex she will. If she doesn't have sex she will continue to bleed monthly, if she has sex she doesn't.

I'm sure some people were dumb enough to not figure it out, but all the important civilizations (ones that could write) knew that pregnancy came from sex.

Sorry but this is bullshit.
There is no human society that does not recognize a link between sex and pregnancy. Some societies have believed that the man just sort of "facilitates" the pregnancy, but all of them recognize that sex is necessary for it.
Until the last few centuries, though, many societies (including Europeans) thought that the sperm contained the entire genetic content, and the woman's body was just a sort of soil in which the seed grew. Hence the metaphor of "seed" for semen, when the seed of a plant is really a zygote.

I know there's at least one of those isolated tribal societies that still isn't aware of the sex/pregnancy connection. They have polygamous families, and each man is conducted to be as much the father of every child in the family as any other because they don't know that a child has a specific father.

[Anonymous No.4390206]

I believe the Aboriginals of Australia did not learn of the sex/pregnancy connection until last century.

Then again ... I probably read that in some eurocentric, racist blurb. I don't really care enough to confirm.

1. It's actually quite hard to become pregnant. It takes many tries. Having unprotected sex won't get your pregnant or stop your periods.

2. Miscarriages are VERY common. Bleed monthly, then have sex, you may not bleed next month, but you may the month after.

3. Periods can vary in intensity.

4. Some girls may never get pregnant at all.

You're still a virgin, aren't you?

[Anonymous No.4390212]

>>4390201
This is a point I was going to raise: Why have the father/mother/child(ren) relationship if it is not known that the man has anything to do with the pregnancy. Looking back, most important societies recognised this as the main family unit, so by extension we can assume they knew that the father was actually getting the baby mamma pregnant without even looking into it.

> one of the first person to ever really understand procreation.

That's such a vague statement. In 100 years future scientists will be considered the first people to ever really understand procreation because they will solve the question of determinism in the fertilization process. In another hundred years the scientists will once again be the first people to ever really understand procreation because they'll solve the question of what causes attraction and exactly map out fertility as a function of genetic and environmental factors.

When you say anyone is "the first to really understand X" there's going to be many, many people who are the "first" to understand it. That's a contradiction, of course, so it really means that nobody can be the first to REALLY understand something. You can't just draw the line at some arbitrary point.

None of that implies that they didn't know the connection between sex and pregnancy, i.e. that it is necessary for a woman to have sex before she can be pregnant.

the phyiscal body and brain have the urges whilst the mind is coerced by both to get sexin'. although, the mind has the final say and can think independently with self-discipline

Haha, are you a fan of da Vinci like myself? He said nearly the same thing.

>"The art of procreation and the members employed therein are so repulsive, that if it were not for the beauty of the faces and the adornments of the actors and the pent-up impulse, nature would lose the human species." -Leonardo da Vinci

The scientific explanation though is that beautiful genitalia was never sexually selected for. For instance, we used to sexually select based on physical appearance of most of the face and body, but no one ever got in bed with a hot looking girl, saw her vagina and went "WHOAH THERE! This is ugly as shit, I'm out!"

[Anonymous No.4390247]

>>4390232
Yeah, what I was saying is you can't using the link between sex -> next period not occurring > eventual pregnancy as a chain of cause and effect between sex and pregnancy because periods aren't as reliable as you might think.

[Anonymous No.4390253]

>>4390242
This is very much true, but you have to understand it in historical context. The allegation was made anonymously through a sort of 15 century complaint box. It was pretty much a common prank back in the day. His accuser never stood trial and he was acquitted.

[Anonymous No.4390250]

>>4390241
so, by having the pussy and penis equally ugly (in all) we would not have a preference over a vaginal type, meaning, each person has an equal chance for procreation?

don't get into elasticity. by the time you figure out its loose, its too late

[Anonymous No.4390256]

>>4390205

In addition to those factors:

- there surely have been a lot of cultures where intercourse began before menstruation. Girls could get pregant before ever having menstruations.

- If sex occurs daily, there's just no way to suppose that the pregnancy that begins one day is, for some reason, linked to one particular intercourse weeks ago. Sex happens, and one day, maybe months later, pregnancy happens; there is no way to tell they are linked, unless the sex is occasional enough to make pairwise links between the two events.

- There is a lot of things that typically accompany sex in most culture: marriage, intimacy, cohabitation, various rituals, changes in alimentation, change of social status. If every single pregnancy correlated not only with intercourse, but also with many other factors, there is no way to conclude that sex causes pregancy as opposed to, say, going to live in your husband's home.

He was young when it happened, he was still under the apprenticeship of Verocchio, he wouldn't have had understudies at the time.

It could well be instinctively programmed into us.
It would be a cruel but interesting experiment of having two isolated and different sex children grow up with no given sexual knowledge.

It is likely we (men) are biologically programmed to get horny at the site of a vagina, and just basically know to stick it in.
Most of us just basically stumble upon fapping without being told.

Maybe, your right. Maybe it is instinctive.

When a female is horny, her vagina gets wet, indicating that a source of pleasure.
When a man is horny, he gets hard, indicating that as a source of pleasure.

Anyway, story time.

This drawing was only recently discovered. It was thought to be a 18th century German drawing, and some guy didn't believe it was he tried to buy it at auction for about 20k, but was barely out bid. Years later he sees it again in an art gallery and buys it for 22k. It's been, and is being, analyzed and it is very much suspected to be a drawing by da Vinci of one of Ludovico Sforza's illegitimate daughters. The current estimated price of the drawing is now 150 million dollars.
