Many countries follow the marriage model of a monogamy, as well as our country.However, dating back to the Republic of China, my country established this system for less than a century.In a long feudal society, the monogamy (妾) system is the mainstream.
The produced by a monogamy as a symbol of the progress of human civilization, emphasizing gender equality, is undoubtedly a system worthy of respect in the process of civilization.
But if you look at it from the perspective of biology, this system seems to be hidden in several disadvantages, which may involve the degradation of male reproductive organs, and may even affect the intelligence level of the entire human race.
Why does this view appear?The hidden side effects behind the monogamy are surprising.
When conducting related research on biologists, it is not a human as the experimental object, but the type of vinegar fly as an experimental material to perform the so -called "licking dog experiment".
So, what is a dog licking experiment?In short, this is a way to explore how to quickly get mating rights.Experiments need to be observed for multi -generation vinegar flies, and it is difficult to draw conclusions through only one or two generations.
The experimental results are surprising. After observation of several generations of vinegar flies, the researchers have found that the ability of male vinegar flies to find mating objects is declining.Biologists believe that the lack of competition has led to a decline in the cognitive ability of male vinegar and flies.
Of course, we cannot conduct an experimental observation of human beings for generations.Psychologists have proposed that the improvement of human intelligence stems from the continuous competition between individuals.Competition in the process of love may affect the evolution of intelligence to a certain extent.
At present, we cannot accurately verify whether the monogamous system has really impacts intelligence through specific experiments, but the systems impact on human evolution cannot be ignored.
We know that male reproductive organs do not contain bones, all consisting of sponge bodies, and no penis bone (in fact, the penis bone was originally existed, but gradually in the evolutionary process gradually gradually gradually gradually evolved.disappear).
Biologists believe that there may be a certain connection between male reproductive organs who lose the penile bone and advocate the monogamy.So, what is the basis for this statement?
Here, we briefly explore Tintin bone (penis bone).
In the animal world, many male animals have penile bones, and some animal penile bones are long, such as the penile bone of the male walrus can reach 60cm.
For the marine, such penile bones are important to improve their sexual competitiveness and help extend the mating time.
In comparison, human mating time is relatively short, especially in ancient humans, usually only two or three minutes can be completed.This was determined by the living conditions at that time. Ancient humans could not over -invest in mating in the environment where the potential dangerous surrounding environment.
Therefore, in the long evolution process, human Tintin bones gradually disappeared (or degraded), and ancient humans did not need to rely on Tintin bones to obtain longer mating time.
Some biologists believe that the modern monogamy system may affect the future evolution of human beings because the system lacks necessary competition.According to Darwins theory of evolution, the nature of nature is harsh. Only through continuous competition can excellent genes be inherited, that is, the so -called "physical competition and the survival of the fittest."
However, there are also biologists who have reservations about this view.They believe that human wisdom is also a product of natural selection.The significant feature of humans distinguishes other species is our wisdom and the process of human beings from brutal to civilization.
We inherit human civilization by reproducing, but humans are no longer just a tool for fertility, and we have more lofty goals.
