Men used to have bones at that place but because they were faithful, they were no longer there

Primate species have penile bones but humans do not, perhaps fidelity has dissolved this bone.

You may wonder why the term "boner" exists, wondering why our "11th finger" has no bones. It must be dumped by evolution, because the monkey has a penis that is as long as a finger and like a walrus, its penis can be up to 60 cm long. Why is that?

The scientific name of the penile bone (or onion bone) is bacumlum , which occurs in many primates as well as mammals around this Earth. It is this that makes scientists curious and curious, why do penises have so many shapes, different sizes, and more notably they want to find out why men This type of bone does not exist.

The penis in a mammal.

To find out about the origin of the strange bones that were supposed to be superfluous, scientists looked at the bones of the penis found in excavated areas that existed millions of years ago.

They found that penile bones have evolved and existed in mammals about 95 million years ago, occurring on the first primates on a 50 million year timeline. And from that historical moment, the penile bones begin their evolution: they become very large in some species but smaller in some other species.

For example, a tail-tailed monkey, a monkey that weighs only 10kg, has a penis up to 5cm long. But at the same time, the white-faced, blue-faced monkey is bigger than the dead-tailed monkey, which has a penis less than 5 times smaller, only 1cm tall.

Penile bone samples from many species.

The research leader, Professor Kit Opie from the University of London, said that the length of the penile bone depends on the ability to maintain sexual behavior for a long time - an average time he thinks will last longer. 3 minutes. That is the "strategy " that evolution has given these monkeys, in order to allow male monkey sperm to have enough time to fertilize female monkeys, preventing the monkey from coping and fertilizing with one Other male monkeys.

In chimpanzees, the penis does not have the same length as a finger. This type of bone is short meaning the time spent on the intercourse of chimpanzees is very short, only 7 seconds. In a group of chimpanzees, females will conduct sexual intercourse with all males, in order to avoid the case where the chimpanzees born will be killed by one of the males in the herd."This behavior causes male chimpanzees to think that chimpanzees may be their offspring," Opie said.

Penis bones have all kinds of sizes.

So what about people? If the importance of the penile bone in competing for such a big partner, why do humans lose the penis in evolution? One of the brief reasons for this question is that people who do not belong to the group " have the ability to maintain sexual behavior for a long time" , the average time of people only lasts 2 minutes.

But one strange thing besides this answer is that the Bonobo gibbons only perform sexual intercourse within 15 seconds, but this species still exists in the penile bone (very small, only 8mm). So there is another reason why we are different from those " primates " of primates. Scientists say that, in general, men do not have to compete too much with other men, and usually women choose only one partner.

It is this habit of finding and sticking to the mate that has caused men to lose their penis during evolution , according to estimates by scientists about 1.9 million years ago.

The penile bones in humans have disappeared because the system of human ancestors' partners has changed.

"We think the penis in humans has disappeared because the system finds human ancestors' partners changed at that time," Opie said. "Perhaps this is the definite disappearance point of the penis that is gradually dissipating."

These are just the first pieces of the jigsaw puzzle of the disappearance of this type of penis in humans. We cannot be certain yet, but these evidence makes us feel good to know that when society develops, its behavior is more complete, the concept of faithful life does not necessarily have to be another piece of bone.

As the late comedian Robbie Williams once said: "God gives men both penis and brain, but unfortunately, men do not have enough blood to operate both things at the same time."

"God gave men both a penis and a brain, nhưng không phải là đủ bộ nhớ để chạy cả ở các cùng thời gian".

It has nothing to do with the penis, but this is an extremely favorable opportunity to quote his quote.
