Is it normal to find a girl super hot?

I think I can shed some light.

Yes, we used the concept of hunter-gatherer, but what you didn't answer was "why". When the concept of hunter-gatherer was created by our ancestors, it was because our species believed that women were "missing" something. Just looking at our bodies visually, we didn't understand that some bodies had penises and some had vaginas. We thought that some had penises and these others were "missing" penises. (And obviously these terms for genitalia and sex/gender didn't exist at the time. I'm just using them to explain.)

This made our ancestors infer that those "missing" something on their bodies were not as strong as those who had something on their bodies. Thus why the people with penises went out to hunt, and those "missing" penises gathered food and stayed away from danger. When you think about it, our ancestors were incredibly smart to make this inference- the only problem is their inference was wrong. We understand today that these people are called males and females, and that a typical male is born with a penis and testicles, and a typical female is born with a vagina and ovaries.

This division from our ancestors caused differences in our evolution. Men began to have more muscles at birth in their upper body from hunting. But women actually are stronger in men in many ways- just in their lower body. They tend to have stronger legs and their vaginas can stretch to 30 times its original size to give birth to another human being. But our androcentric world doesn't focus on lower body strength. We don't see purpose in leg strength, we see purpose upper body strength because we can lift things.

Why are women pretty? Some are, and so are some men. Beauty is in the eye of the beholder. Calling women "pretty" and men "handsome" is something we created for gender norms. But ask yourself, who created gender norms? The reason women are "made to be pretty" is because MEN created the gender norms. Following the same mentality for thousands of years, thinking that men were stronger and that women were weaker, men were the ones that decided what the gender roles were when we became homo-sapien sapien, as with the development of politics, our grasps on religion, even science and medicine. For centuries, women were seen as property to men, and that their job was to be concerned with rearing children and pleasing their husbands- because men made it that way with their power. The did "scientific studies" to "prove" that men were stronger. They used religion to justify any difference between men and women, and they kept their control of women using politics. It wasn't until the previous century when Americans finally started to grasp that the people who believed these gender norms were wrong.

Even today in movies, magazines, television- all types of media- the ones telling women how to dress, how to shape their bodies, what to do with their hair, make-up, and breasts... it's mostly men. Women are de-humanized in our media and seen as objects to men. They made breasts sexualized parts of the body, which is why in the U.S. men can take their shirts off in public but women can't.

I know I went on a bit of a rant, but If you get a chance you should read some feminists theory. Simone de Beauvoir is a great french feminist theorist to start with. You might also enjoy some feminists works of Monique Wittig (another French feminist), Kate Bornstein (a well-known writer on gender), and bell hooks (a writer on women's movement as well as african american equality - her name is NOT capitalized). Just give it a try before you stayed convinced that men and women are so different.

The answer to your question is in my comment above. And 2.2 million years is long enough to form the primal instincts, homo sapiens or not.
