Just when Long Yun was thinking wildly, the sound of rushing water had stopped.

Hearing the sound of the deadbolt, Long Yun looked up and saw that Shangguan Ling had already come to the front and took the bath towel from his hand.

"-Phew, the water temperature is good today, and I am very happy swimming."

Shangguan Ling, who had already put on a swimsuit, wiped the residual water stains on his body with a bath towel; Seeing Long Yun's eyes, she was a little stunned, she withdrew her slender legs on the chair, and glanced at the man sitting on the side a little suspiciously.

This Long Yun, what kind of eyes were there just now?

She has seen too many dementia symptoms like that, can she say that he is the same?

"Ling, it seems that you exercise a lot."

"- yes, what?"

To Shangguan Ling's surprise, Long Yun's confused eyes only flashed, "Your calf tibia is quite long, you should be born from regular horizontal exercises, such as swimming." ”

What Long Yun said was actually what he thought just now, he didn't look at women out of eroticism, but often with a bit of research.

is a little different from the posture of ordinary women, Shangguan Ling's well-proportioned calves are quite eye-catching, and it can be seen that the tibia is almost as long as the femur; In addition to the genetic advantage, the stimulation of the tibial cartilage layer by acquired exercise is also important. With slender calves, it is easy to be tall and tall, and it is difficult to think of an outstanding figure, and he is actually expressing his heartfelt appreciation.

"Oh, really?"

Feeling that this man's words were a bit novel, Shangguan Ling responded and looked at him deliberately, but he didn't see any urgency on his rather focused face.

Looking back on the previous experience, those wild bees and butterflies that lingered around her were nothing more than coveting her beauty or straight breasts, and staring at her legs really didn't look much; As for the length of the tibia like him, this is the first time Shangguan Ling has heard of it.

"Because of the sport, I still know that. Is it good-looking? ”

"Yes." Long Yun nodded, "It looks really beautiful." ”

Although Long Yun himself does not think that there is any difference between genes and inferiority, but from ancient times to the present, the ratio of calves to thighs is indeed slowly increasing.

Relatively speaking, this also means that women with slender calves are more "evolved", and the power of natural selection will also make men feel that they look more beautiful. Because such a structure can increase instantaneous explosive power, but will reduce the level of endurance at a certain level, the environment that can allow this kind of genetic growth must be relatively comfortable and calm, and there is no protracted struggle, which is also the general direction of human social progress.

Seeing Shangguan Ling's eyes, Long Yun simply said his theory in a few words, and the eldest lady listened with a little relish: "In this way, natural selection will promote people's genes and develop in the direction of beauty?" ――In layman's terms, there will be more and more beautiful women? ”

"Unfortunately, that's not the case. This trend is only an increase in the overall average, and the definition of beauty is 'an above-average individual', and this proportion will not change. - Moreover, for particularly outstanding individuals," Long Yun glanced at Shangguan Ling thoughtfully, "because the competition is too fierce, it is often difficult to have more offspring. ”

"Too much competition?" Shangguan Ling obviously didn't quite understand, "What do you mean?" ”

In other words, because men are quite eager for such women, the situation of competition with each other will hurt the interests of women. To take an extreme case, uh," Long Yun didn't know whether to say it or not, "For example, the more beautiful a woman is, the greater the temptation, if she falls into the dust, has experienced abortion, sexually transmitted diseases, or even physical injury, do you think she will have many healthy offspring?" ”

"-Oh? …… But that's no longer the case, isn't it? ”

"Extinct? Do you say yes or no......"

Long Yun thought to himself, how could it not be, is this eldest lady too naïve or what?

To his surprise, Shangguan Ling seemed to frown and ponder for a moment when he heard Long Yun's words, and then spoke again to express his agreement.

"Yes, I think that's still the case. You mean, a condition like beauty isn't all an advantage in the face of competition for survival, is it? ”

"That's pretty much it. -- Frankly speaking, aren't those who have been sexually assaulted or even killed by a relatively beautiful woman? How does this behavior affect our genes in the long run? The law is now powerless to punish such behavior, and I can only be optimistic personally.

Therefore, on the whole, the proportion of beautiful women in the population cannot be increased, but there is a risk of decreasing; Unless a planned family strategy is carried out, which is completely unfeasible either legally or ethically. ”

Speaking of this, Long Yun sighed a little abruptly. He knows that such a theory means that the operating mode of human society will not change for many years, and it is still the competition of almost all men around scarce beauties; As for anything else, in the final analysis, it is just a peripheral preparation for this kind of competition.

From people's enthusiasm for work to the country's military expansion and warfare, in fact, this is all the same. Not only that, but this kind of unconventional competition itself may also cause counterproductive consequences: those rich people, or playboys, constantly consume this scarce resource in order to satisfy their selfish desires; Will this make it impossible for their genes to reproduce, and they will disappear from the genetic makeup of the human race?

As Louis XV's mistress Pompadour put it, they were simply "the flood after death".

"Long Yun, your idea is very interesting."

"Ah, what?"

"I mean, your idea is very unique, at least it's the first time I've heard it," To Long Yun's surprise, Shangguan Ling was now kind to him, with a little smart interest in his eyes: "I have decided, the next paper will elaborate on this issue, and you will be the co-author; When I have time, I want to have an in-depth communication with you! ”

Yes? What is this eldest lady going to do, to write a thesis on this kind of topic?

However, before Long Yun came back to his senses, Shangguan Ling's next words made him completely shocked:

"But to be honest, I personally don't agree with your theory right now. Just talk about myself, do you think I'm beautiful? - Forget it, I don't need to ask you. Even with such physical conditions, I don't feel that my reproduction is threatened; On the contrary, I have the confidence and ability to find a husband who is happy and have many healthy children, which is probably contrary to your theory, right? ”

After saying so much in one breath without any scruples, Shangguan Ling suddenly woke up from the state of debate; Realizing that her words just now were too explicit, she lowered her head slightly with a little crimson, and turned to put Long Yun aside.

…… Multiply? Looking for a husband? Have a lot of children? Is this the inner monologue of this eldest lady?

Long Yun only felt that the conversation just now was really embarrassing, and he didn't know what to say for a while, but he also understood Shangguan Ling's unique personality and way of thinking quite thoroughly.

This girl is indeed full of personality.
