The man organ is " Show off the organ " (used at the end of a question)?
In all gender characteristics of mankind, not more noticeable than the man's sexual organ. Through the ages, in all parts of the world, the idol that the man's genitals are often deemed to worship by the clan. However, though the primitive artist has ever portrayed the image of the man organ many times, though the mankind can trace back to history that the male organ worshipped 10,000 years ago, during long years. People have not all had a contradiction making the person puzzled to discover the male organ on the shape. This contradiction, until being put forward by the anthropologist in recent years, become a mystery. In studying the life shape, biological evolution, dissecting the physiological field, compare it is a very important research means. Just in comparative study, the anthropologist has found and proposed a contradiction on the man organ shape. Generally speaking, size and its size size of sexual organ of the male animal become direct ratio. However, the sexual organ which takes the human man is compared with four kind apes in existence, the result but it is not like this. The gibbon, orangutan, gorilla, chimpanzee and mankind, that had the biggest size is the male gorilla. The average weight of the male gorilla can be up to 200 kilograms, and the human man's average weight is less than 100 kilograms. If ask, in these kinds four ape and the mankind, is it the longest which one kind of penis is the biggest? Answer assuming as a matter of course in people's big city: Gorilla. But the fact is not like this. The average length is 3.4 centimetres when the penis of the gorilla erects; Chimpanzee's average length is 7.5 centimetres; But the average length reaches 15 centimetres when the human penis erects. Average length of the human penis is 4 times of the gorilla, it is 2 times of the chimpanzee. Moreover, because the human skin uncovers, in view of shape, the human penis is also the most noticeable. And the penises of the gorilla, chimpanzee, it is difficult to be found even while erecting. Why human size is smaller than gorillas far but is the penis length 4 times of the gorilla? Nearly all penises of the male ape are short and small but not showy, why only human exception? Why does the mankind need so big and showy a penis? Whether this is representing a certain useless evolution trace, or because of or and the evolution " by product " produced that the finger is flexible that the cerebral cortex is developed ? All these are questions not very apt to answer. As to this phenomenon difficult to explain, the anthropologist puts forward the hypothesis from two respects, attempt to expound. Some researcher view that the neutral behavior meet go on, think from evolve, but other researchers infer in terms of competition of evolving. From the standpoint of sexual behavior, U.S.A. and some of Britain study the behavioral expert of primate to propose, the phenomenon of very great this of human penis is caused by human special sexual behavior. Mankind's traditional face-to-face sexual intercourse posture, the change does not have sexual intercourse habit of the party, each sexual intercourse duration is relatively long, these sexual behaviors make the human shape in conformity with it in the evolution, impel humanbeing evolution produce longer penis. After this hypothesis is proposed, are refuted by many researchers. It shows to observe, in the apes. There is a kind of chimpanzee at least - -Chimpanzee to used to, adopt face-to-face the intersection of sexual intercourse and posture too in order to doses of rice. And orangutan and gorilla adopt this kind of posture sometimes. In sexual intercourse traditionally, the orangutan is the most changeable, they sometimes adopt the face-to-face posture, sometimes adopt it in the face of carrying or side posture, can be rotated and mate on the branch to even hang. But they have not evolved out very big and showy penis has come. As for duration for sexual intercourse, though the mankind is relatively long. But not the longest. According to study, U.S.A. each sexual intercourse 4 minutes in duration for each person. The mating time of the gorilla is one minute, the chimpanzee is 8 seconds, but the mating time of the orangutan can be as long as 15 minutes, far exceed the mankind. Because of fact these, adapt to angle come, explain from sexual behavior human penis why be very much long, seem that is hard to tell openly. Other researchers are in terms of competition of evolving. Have proposed " Show off the organ " Hypothesis. The thought based on Darwin's natural selection of this assumption, think the human penis the reason why grows up but showy, because the human penis is so-called " Show off the organ " ,Like the magnificent tail feathers of the male peacock, the mighty mane of the male lion is the same, show off the organ useful to struggle for existence, have the tendency to strengthen in the evolution of long years gradually. This hypothesis has caused doubt too. Penis show off organ as man, these what a kind show off? To whom to show off? Some anthropologist think penis show off the organ as first kind, the target of showing off is the man competing for each other. American anthropologist Mr. and Mrs. Diamond are while investigating in the primitive tribe of New Guinea, have found favorable to a circumstantial evidence of this kind of view. Though man in those primitive tribes is naked to reveal the body, use a kind of peculiar " penis sheath " To dress up oneself. Each adult man have several a such one " The penis sheath " . Sheath 30 or one 60 centimetre long, 8 or one 10 of diameter, sheath have feather to be ornamental at the head. Diamond thinks this kind " The penis sheath " It is the penis that, as the extension showing off the organ, aim at showing off to the man competing for each other, though to person of the civilized society, such showing off is unable to think of discussing, but in the primitive and human evolution, the showing off of male organ perhaps played the function of the natural selection in trying the spouse's competition, produce the motive force of impelling the penis to evolve towards the big and showy direction. The researcher still quotes man's genital symbolic art in the man right society at all times as the evidence, to prove this fine art was created and shown off to other men by some men. The biological organ evolves in coordination, the man bright stem is limited by woman's vagina in the evolution, without this restriction, as showing off the organ. Stage different to imagine that the penis may evolve getting greatly. This kind of explanation lacks to the direct observation evidence of the competition in the primitive tribe. Other anthropologists think, the penis, as showing off the organ, attract the showing off of the opposite sex, the target of showing off is a woman, instead of the man. This kind is shown off and taken place in the long evolution course from ape to people. But American the intersection of sex and psychology that psychologist make investigate conclusion seem unfavorable to this hypothesis. When asking about which characteristics the man can cause their interest even more, the answer of women whose majority is investigated is that the man's voice, leg, shoulder and buttocks are more attractive than the penis size. Same sex behavior meet hypothesis to be the same, penis face criticizing as the hypothesis of showing off organ for and dispute, still can't justify oneself. Though scholar make all sorts of hard efforts already, male organ still very heavy doubts and suspicions to head of thinking.
