Unlike other bones in the body, it is wrapped in soft tissue and is not connected to any bone. It is a completely independent bone. It is a bone on the genitals of a mammal, independent of the skeleton. It can help animals stay invincible in the "mating war" of survival and reproduction. The most amazing thing is that it can also hook the germ cells left by a male from the female body to ensure that its bloodline can be continued.

Known functions include.

Stimulation: In some mammals, such as lions and domestic cats, the female body will ovulate only when she is stimulated enough during mating. With this bone, males can effectively improve the success rate of mating and reproduction.

Delay: The most direct benefit of rod-shaped bones is that they can allow males to mating for a long time. For males, this is not just a good way to spend an afternoon. Long-term mating can also effectively prevent females from sneaking away before the germ cells work and then mating with other males.

Harm: Some male mammals have special rod-shaped bones. When they mated with females, they can easily damage the female's reproductive tract. In this way, injured females can no longer mated with other males in a short period of time. In this way, males can effectively ensure their own reproductive success rate.

Cleanup: Some males have rod-shaped bones that are hook-shaped. During the reproduction process, they will use this "hook-shaped bone" to clear out the germ cells left by the previous male in the female body, thereby increasing the success rate of their own reproduction.

Speed: The last function of rod-shaped bone is speed. For example, a male lion needs to mating for more than 200 times in a few days. Whenever mating is completed, you must always prepare for the next lioness willing to mating.

From the above 5 points, it can be seen that the ultimate purpose of males having rod-shaped bones is to increase the reproductive success rate. It is never for pleasure. Moreover, this "excessive bone" is very unfriendly to the opposite sex, and it can even be said to be extremely harmful.

However, in the primitive jungle where survival competition is cruel and fierce, the animals have nothing left to defeat their own kind, seize reproductive advantages, and allow their offspring to reproduce. The evolved rod-shaped bones can just help male animals compete fiercely, such as quickly mating to conceive females, keep the germ cells extremely active, and prevent other competitors from taking advantage of their precautions to zip out the germ cells they have just launched. In order to survive and reproduce, similar animals are also fighting fiercely. In the survival of the fittest of animal evolution, those animals that do not grow rod-shaped bones will be disliked by females, or defeated by similar animals, gradually at a disadvantage and eventually disappear and extinction.

It is said that among all living things, humans have become the only two creatures without rod-shaped bones, and the other one is the spider monkey.

Research has proved that rod-shaped bones evolved in mammals 100 million years ago, and most animals are still retained today. For example, tigers, lions, cats, dogs, etc. It is believed that humans also had rod-shaped bones at the beginning. However, about 4.5 million years ago, primitive humans parted ways with their close relatives primates and headed towards different evolutionary routes, and rod-shaped bones were slowly abandoned. In-depth research has found that humans "delisted" rod-shaped bones at the genetic level during a long evolutionary process. Compared with the DNA of primates, the gene encoding of rod-shaped bones is likely to exist in the 510 groups of DNA missing by humans. This is obviously a dwarf gene that was "deleted" during human evolution.

Further research has found that the disappearance of rod-shaped bones is also the price paid by humans when they evolve from walking on their limbs to walking upright and their brain capacity increases. Scientists found from comparative experiments of mice that once the normal growth rate of rod-shaped bones of mice is damaged, their brain capacity will be monitored to be significantly expanded. That is to say, in order to adapt to walking upright and improve brain capacity, humans sacrifice rod-shaped bones. From the advanced nature of evolution, brain evolution is preferred and efforts are concentrated to improve brain capacity. This is the inevitable path for humans to become higher living organisms.

When the path of evolution is determined, the structure of human society that is compatible with it has also undergone a fundamental change. From a unique and exclusive reproductive right that only the strongest male in the population can have, it has transformed into a monogamous civilized education model.

In general, it is precisely the evolutionary model of human beings' own "survival of the fittest" that leads to the "exit" of rod-shaped bones. Losing rod-shaped bones is not a stupid choice or evolutionary omission, but instead makes its own advantages more prominent (is it true, adults?). From the appearance, the rod-shaped bones of animals grow in the abdomen, which female creatures cannot see at all. After losing, they will become larger and exposed, which also has a more intuitive stimulation in attracting the opposite sex. Human beings have only adopted a more advanced method to adapt to the new reproduction model.

Of course, another conclusion that can be drawn is that brain capacity and fertility are in an unknown inverse proportion. Simply put, the dick has a small brain and vice versa. So for contemporary women, the most important life choice is in front of you. Should you choose to be better for yourself or better for the next generation?

Director Giovanni took out a handkerchief to wipe away the tears of the young actress Sarah Drayton: "So humans have never been cold-blooded animals that put patriarchal power first. Men are not as powerful as they look. Because "men have one weakness, they also have a soft dick." Smart women will bravely meet them, grit their teeth and grab the man's weakness. Smarter women will wait for the man to pounce on them, and then cry and grab the man's weakness."

"Puchi--" Actress Sarah Drayton couldn't help laughing. This sentence came from the mouth of the great director who controls everything, and it actually had an unusually profound connotation. It was also the reason why the young actress burst into tears and laughed.

"Remember, Sarah, my beauty. Women are born with the power to accommodate, soothe, guide and squeeze men." Director Giovanni said in a tone that was almost transcendent. The director is indeed a person who has experienced it.

"This conversation goes beyond the movie itself." Mrs. Katy, who witnessed everything throughout the whole process, was inspired. She was also the best among women who accommodated, soothed, guided, and squeezed men. "The outstanding lady of Germanic". She had long known that men's "soft knife" was just pretending and could not kill people.

As he was talking, the outdoor shooting site suddenly became commotion.

Several assistants rushed in and handed the colorful leaflets in their hands to Mrs. Katie.

"(War) is coming." When I saw clearly the pornographic flyers scattered by the Allied planes held in the assistant's hand through the anti-aircraft artillery fire and the "surrender certificate" specially cast for the Italian army, the battlefield girl Danielle knew clearly that the plot was accelerating. The final harvest also quietly accelerated its pace.

"It seems that I can't wait for the movie to be finished." The female reporter picked up a "surrender certificate" that the assistant accidentally dropped from the ground.

"Use the "B-level plot fragments of the Great Battle" branch under the "0326 exclusive branch plot main line" to promote the "Mummy A-level plot fragments" branch plot line; use the "Plot Kill" of "Plot Ending the Drama" to solve the major problems in the Ziyuan branch plot. Isn't it the ultimate goal when we came?" Battlefield girl Danielle smiled.

"Considering the upcoming Eastern adventure, our team must not be without Mrs. Katie." The female reporter who was awarded the "Time and Space Patch" in advance said his heart.
