research found that many male animals have a bone in their private parts, such as male gorilla . This bone plays an important role in the process of reproduction of offspring. It can allow males to enter the state anytime and anywhere and carry out the work of reproduction of offspring.
However, humans are exceptions, and there are no bones in the private parts of human men. However, research shows that early humans, like many male species, once had a bone, but they did not evolve the bones during the evolution process. Why is this happening? Why has the bone evolution not affected human fertility?
Scientific research has found that the loss of the bone in human males is likely to be related to sexual selection.
Different species have different sexual selection methods, which has a lot to do with reproductive strategies. In most cases, males can produce tens of thousands of sperm, but females can produce only very limited eggs.
In the animal world, in order to maintain their genes as much as possible, most male species will find as many opportunities as possible to mating and reproduce, but generally they will not be furious to the rearing of their offspring.
. Female is more cautious when choosing mating subjects. In order to ensure that their offspring has better genes, they are usually very picky and will not breed offspring with males at will.
So, in order to obtain the right to mating with females as much as possible, males have evolved many different characteristics to attract females. For example, stronger male lions are more likely to gain favor from females, while peacocks rely on their gorgeous appearance to attract females.
Back to the topic, scientists believe that the disappearance of bones in human male private parts is also related to women's sexual choices.
When humans were just born, like many animals, humans did not wear clothes, and their private parts were exposed. In this case, women can choose their spouse by intuitively observing the male's private parts.
So, in primates, some males will attract the attention of females by showing off their privacy parts.
However, scientists believe that the reason why human men lose that bone is mainly because women do not value that bone, and they can still win the favor of women without bones. Also, the private parts of human males are the largest of all primate species. They are composed of numerous elastic fibers, which can control the size, softness and hardness of the private parts. There is no bones and no big impact.
Another point is that humans are basically monogamous and can have their own offspring. They do not need to continue their genes through large reproduction like in the animal world!
