It is different from other bones in the body. The rod bone, which is wrapped in soft tissue and not connected to any other bone, is a completely independent bone. It is a bone in the genitals of mammals, independent of the skeleton. It can help animals remain invincible in the "mating war" for survival and reproduction. The most amazing thing is that it can also extract the reproductive cells left by the previous male from the female body to ensure the continuation of its own bloodline.
There are known effects.
Stimulation: In some mammals, such as lions and domestic cats, the female's body will only ovulate when she is sufficiently stimulated during mating. With this bone, the male can effectively increase the success rate of mating and reproduction.
Delay: The most direct benefit of the rod bone is that it allows males to mate for a long time. Not only is this a great way for the male to while away an afternoon, but prolonged mating also prevents the female from sneaking off to mate with another male before her germ cells have functioned.
Injury: Some male mammals have special rod-shaped bones. When they mate with females, they can easily injure the female's reproductive tract. In this way, the injured female will no longer be able to mate with other females in a short period of time. Males mate. In this way, males can effectively ensure their reproductive success.
Cleaning: Some males have hook-shaped rod bones. During the reproduction process, they will use this "hook-shaped bone" to clean out the germ cells left in the female body by the previous male, thereby increasing their own reproductive success rate.
Speed: The final function of the rod is speed. For example, a male lion needs to mate more than 200 times over several days. Whenever mating is completed, preparations must be made for the next female lion willing to mate.
It can be seen from the above 5 points that the ultimate purpose of males having rod-shaped bones is to increase the success rate of reproduction. It's never about pleasure. Moreover, this "extra bone" is very unfriendly to the opposite sex, and can even be said to be extremely harmful.
However, in the primitive jungle where the competition for survival is cruel and fierce, in addition to resisting natural enemies, the only thing left for animals to do is to defeat their own kind, seize reproductive advantages, and allow their offspring to reproduce. The evolved rod-shaped bones can help male animals compete fiercely, such as rapid mating to impregnate females, keep reproductive cells extremely active, and prevent other competitors from taking advantage of them and unpreparedly draw out the reproductive organs they have just launched. cell. In order to survive and reproduce, similar animals also fight fiercely with all their strength. In the survival of the fittest in animal evolution, those animals that do not grow rod-shaped bones will be rejected by females or defeated by similar animals, gradually being at a disadvantage, and eventually disappearing.
It is said that among all living creatures, humans are the only creatures without rod-shaped bones, the other being spider monkeys.
Research has proven that rod-shaped bones evolved in mammals as far back as 100 million years ago, and most animals still retain them today. Such as tigers, lions, cats and dogs, etc. It is believed that humans also initially had rod-shaped bones. It was only about 4.5 million years ago that primitive humans and their close relatives, primates, parted ways and took different evolutionary paths, and the rod-shaped bones were slowly abandoned. In-depth research has found that humans have "removed" the rod-shaped bone at the genetic level during the long process of evolution. Comparing the DNA of primates, the gene coding for rod-shaped bones is likely to exist in the 510 sets of DNA that humans lack. This is apparently a dwarfing gene that was "deleted" during human evolution.
Further research revealed. The disappearance of the rod-shaped bones is also the price paid when humans evolved from walking on four limbs to walking upright and when their brain capacity increased. Scientists have found from comparative experiments on mice that once the normal growth rate of the rod-shaped bones of mice is disrupted, their brain capacity will be significantly expanded. In other words, in order to adapt to upright walking and increase brain capacity, humans sacrificed the rod-shaped bones. From the perspective of evolutionary advancement, priority should be given to brain evolution and efforts should be concentrated on increasing brain capacity. It is the inevitable path for human beings to become advanced life forms.
When the path of evolution is determined. The corresponding human social structure has also undergone fundamental changes. From the exclusive right to reproduce that only the strongest male in the population has, to a monogamous civilized upbringing model.
In general, it is precisely human beings' own evolutionary model of "survival of the fittest" that has led to the "exit" of the rod-shaped bone. The loss of the rod bone in humans was not a stupid choice or an evolutionary oversight, but rather served to enhance our own advantages (is that true, my lord?). From the appearance point of view, the animal's rod-shaped bones all grow in the abdomen, and the female creatures cannot see them at all. After losing it, it will become larger and exposed, and it will also have a more intuitive stimulation in attracting the opposite sex. Human beings have just adopted more advanced methods to adapt to the new reproduction model.
Of course, another conclusion that can be drawn is that there is some unknown inverse relationship between brain size and fertility. Simply put, dicks have small brains. vice versa. So for contemporary women, one of the most important life choices lies before them. Do you choose to be better to yourself or choose to be better to the next generation?
Director Giovanni took out a handkerchief to wipe away the tears of young actress Sarah Drayton: "So human beings have never been male-dominated cold-blooded animals. Men are not as strong as they seem. Because "men have only one weakness. , and a soft dick." A smart woman will bravely go up to him and seize the man's weakness with gritted teeth. A smarter woman will wait for the man to pounce on her, and then grab the man's weakness with tears. "
"Pfft..." Actress Sarah Drayton couldn't help laughing. This sentence comes from the mouth of the great director who controls everything, and it actually has an unusually profound connotation. This is also the reason why the young actress burst into laughter.
"Remember, Sara, my beauty. Women are born with the power to accommodate, comfort, guide, and squeeze men." Director Giovanni finally said in an almost detached tone. The director is really experienced.
"This conversation transcends the movie itself." Mrs. Katie, who witnessed everything throughout, said with emotion. She is not the best among women who can accommodate, comfort, guide and squeeze men. "The outstanding lady of Germany". I have long known that a man's "soft knife" is just a pretense and cannot kill anyone.
Just as he was talking, the location shooting location suddenly became commotion.
Several assistants rushed in and handed the colorful leaflets to Mrs. Katie.
"(War) is coming." When she saw clearly the pornographic leaflets dropped by Allied planes passing through anti-aircraft fire and the "surrender certificate" specially delivered to the Italian army in the assistant's hand, the war girl Danielle knew clearly. , the plot is coming to an end quickly. The final harvest has also quietly accelerated its pace.
"It seems that I can't wait until the movie is finished." The female reporter picked up a "surrender certificate" from the ground that her assistant accidentally dropped.
"Use the "Battle B-level plot fragments" branch plot line under the '0326 exclusive branch plot main line' to promote the "Mummy A-level plot fragments" branch plot line; use the "plot killing" of the "plot ending plot" to solve Ziyuan A major problem arises in the side plot. Isn’t that the ultimate purpose of our coming?” War Girl Danielle smiled.
"Considering the upcoming adventure in the East, our team cannot be without Mrs. Katie." The female reporter who was awarded the "Space-Time Patch" in advance said her heart.
"Of course." Battle Girl Danielle also had the same idea: "Not just Mrs. Katie, all the selected 'characters' in my hands are going to go on the road together."
