In the ancient world of creatures, males often had to show their charm in order to compete for the right to mate. For example, peacocks will open the screen, lions will erect their manes, humans will not be outdone, and men will slap the keys of rented luxury cars on the table to show their wealth. And Tintin, as the iconic organ of male animals, not only carries fertility, but also hides some unhuman secrets. Sour bones are called ** bones by scientists. It is ubiquitous in mammals and varies in morphology.
You can boldly use your imagination, if Ding Ding is compared to a spear, then ** bone is the spearhead. It plays a better supporting and immobilizing role in the process of mating in male animals, which can increase the probability of mating components. Incredibly, in some species, the bones have even evolved into particularly strange shapes, such as tridents, and of course this is also to accommodate the mating needs of different requirements.
Surprisingly, humans, as mammals, have lost this bone in their evolution, why?
In the continuous evolution, human beings have gradually given up their bones to adapt to more diverse and complex sexual behaviors. Compared with other animals, due to the continuous development of consciousness in the evolution of human beings, human beings pay more attention to the establishment of intimate relationships and the expression of emotions in the process of reproduction, and have long been separated from the simple purpose of reproduction. Based on these factors, the human ** bone disappeared, and the structure and function of Tintin also underwent some changes.
Humans without ** bones, among mammals, are more distinctive. For example, humans are more sensitive and can quickly complete a set action in a short period of time.
Scientists have deduced the mating behavior and evolutionary process of different species from these large and small bones, for example, scientists have found that in primate animals, the species with the bones usually have a longer mating time, which is also related to the strong competition between males. In some carnivorous animals, it was found that the shape and size of the bone are compatible with the structure of the female, which further proves the miracle of nature, in the evolution of organisms, pay attention to the principle of only one key for a lock.
The existence of the T-T-bone is not surprising, but it is not surprising. Charles Darwin once said that what all living things will become in the process of evolution is based on natural selection. At present, the biggest difference between humans and other mammals when mating is that human reproduction is carried out in a relatively comfortable environment, and there is no need to worry about the risk of being eaten by predators at any time, so it does not have much impact on human beings, after all, there is no external pressure for humans to stand up in 3 seconds, and it is not excluded that humans are faster than giraffes! (3 seconds before and after the giraffe).
In short, although the human bones have disappeared, this strange structure of mammals reveals for us the diversity of biological evolution, as well as mysteries that we have never heard of, or even imagined. In this magical earth, there are still too many unknown areas waiting for human beings to explore. Human development and progress require a lot of curiosity and curiosity.
As for the fact that you don't have this bone, don't be too anxious, pinch your fingers, you belong to the "big instrument" late formation.
