Why do the females in our species become sexual BEFORE they become fertile?

Let’s be realistic. We may try and pretend that girls don’t become sexual until some socially approved age like 16 or 18 but the biological reality is that it happens at about 12. When the hormones kick in they develop an interest in sex and become sexually ornamented with boobs, pubic hair and sharper adolescent facial features that the males soon notice.

Now this is interesting because the typical age that girls would start ovulating and become fertile in prehistory was probably not until about 14. It looks like evolution has engineered girls to become sexual a couple of years before they become fertile.

What purpose does this serve?

>I think there's probably hidden structures within the brain that are unknown by science that would explain a lot of the sexual behavior that might develop before puberty.

Rub genitals = feels good. Rub genitals a lot = feels REALLY good. Rub genitals with another person = feels good and FUN!

Is it any wonder that so simple a thing can be figured out by kindergarten-age children? There is no magic or secret to sexuality; the concept of "sexuality" is entirely created by society and it's mores and laws and stipulations and expectations. Humans do not HAVE much of a built in sexuality, so there is nothing biological or psychological to discover.

unlike women

It seems that society does not give a fuck

We have a defined sexuality, which can be male or female, or other anomalies, even before we are born. Now, our sexual response is other thing, we can see kids kissing, that is more a secondary thing if the real purpose was to fulfill something, his desires to form part of something bigger and more complex with someone, although, their minds aren't prepared for that at an ethical nor operational level (a level that they are aware of the situation and can abstract it). The human sexual response is turned on since the human can feel sexual pleasure (basically since we have our nervous system and reproductive system), and we feel sexual pleasure because it makes the whole intercourse process a pleasant experience, wanting us to procreate more and more. Now, why the females become sexual before they become fertile? Maybe it's a bit hard to create a whole new system inside our body once the time has passed and we need it, and because the older we get, more time is needed to create tissue (and because all of the dangers our ancestors had, it was better to have it the sooner, so they don't need to wait the system to create and become functional to procreate and spread the species)

Why we can feel pleasure since kids and not when we become fertile? Because our nervous system is needed for that, and our nervous system take time to regenerate/create and become functional, at least in the level of complexity of the reproductive system. Other thing is the urge to fuck everything we see at a certain age, but that is for other day, i'm tired and have to study a fuckton of things tomorrow.

Good night good people.

Can someone explain in simple terms what "reproductive value" means?

And why does it peak at 17? What's so special about that age?

But human sexual preferences also have a significant memetic component, they are not purely biological.

They mostly fixed by biological necessity, though, otherwise they would be open to be altered into something maladaptive.

How true has this statement been proven?

It has not been proven true because the statement is clearly false. I dare anyone here to find a drug which can divide by seven or remember what it had for breakfast this morning.

what is the psychology behind rationality skepticism and forming hypothesis?

I feel it's impossible to research this with academic search engines because of the terminology.

Hello /sci/.

I'd like to know the efficacy and effectiveness of free online courses from major universities, such as the ones listed here:
http://www.openculture.com/freeonlinecourses

I'd also like to know how they compare to the actual courses one must pay tuition for. I've been thinking of learning about several subjects which are offered on this list, from ancient Roman history to music theory, but most of the subjects I hold interest in are science related.

Is it possible to find out who a person in a picture is without exif data? Is facial recognition a functioning thing that can find people just based off a picture of them? Or is that stuff PIs are only able to do?


>>
CandleJack 13/04/27(Sat)03:38 No. 14991 ID: 2f260d

Software is easy. A high-school student could probably write a functional facial-recognition program.

Unfortunately, without a database of faces to compare it to, it would be useless. Only governments have access to those kinds of databases, not you.

The toughest field in human academia is probably sociology.

Because humans are not logical or reasonable or predictable, especially in groups. Anything founded upon math (which encompasses basically all physical science) is easy because it makes sense and follows rules.

Any biotechnologists or neuroscientists in the house?

Are we anywhere near the point of being able to use surgery/robot-surgery to improve the brain directly?

There are already indirect methods, crude pharmaceutical applications that exploit the blood circulation system to get to the brain, but why not directly alter brain chemistry, surgically enhance brain physical structure, or 'trick' biological mechanisms into improving the brain?

On the same topic, why don't we, and if we can't, how many years are we off being able to implant technology into the brain to act as a peripheral device?

Imagine having an AI interface for your eyes!

It's not possible. Nobody has any idea how the brain even works, and there is only a rudimentary understanding of how it's arranged (as in, what parts of the brain have what approximate function). It is not possible to modify what is not understood without performing mad-scientist-level experiments of living persons.

Since such experimentation is unlawful, it will probably never happen.

This just in, guys. TIME MAY CEASE TO EXIST SOME DAY.

Apparently entropy is breaking news now.

Do any of you guys ever encounter redundant, or frankly stupid science articles? Not stupid theories (the one in the linked article is interesting, to say the least) but articles that just suck at portraying the message of what it's about?

Sorry, no time to explain this.
The trouble with seeing time as a dimension is how can you visualize rotating a cola bottle 90 degrees in time? You can rotate it 90 degrees between any two of the three dimensions. The problem is that physical length is fundamentally different from time just as time is fundamentally different from mass and mass from length.

Still it is a fun idea to play with. If you could do such rotations, you might be able to turn it inside out without opening it.

CandleJack 13/04/27(Sat)03:42 No. 14992 ID: 2f260d

>>14986

Time isn't a physical dimension, so a physical rotation is meaningless. One could rotate the cola bottle 90 years, in which case it will — depending on the direction — either end up smashed (or in the form of pieces of other glassware after recycling) or as sand (which it was before being glass).
