Evolution - Face

Researchers from the University of Utah in the United States announced the results of their research on the evolution of human faces in the journal Biological Research on the 9th. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

They believe that an analysis of fossilized Australopithecus bones dating back between 5 million and 4 million years shows that the hardest parts of Australopithecus' face were also the most vulnerable to blows and injuries during the fight, including the lower jaw, cheekbones, bridge of the nose and orbital skeleton. Therefore, the human face, especially the male face, has grown into what it is today, precisely to minimize the damage caused by the process of "being slapped in the face".

Although the 6 million years of human face evolution comes down to "hitting people without hitting their faces" is a bit funny, but staring at those contrasting pictures, do you have new ideas?

Don't be fooled by authority. The only argument that supports this is probably that the human brow bone does not protrude forward.

Evolution will eliminate the undesirable.

What is the most conspicuous target of the human face in the theory of fighting evolution?

That's right, the big nostrils.

If it is the evolution of fighting that determines the evolution of the human face, then why did humans evolve a high nose on the face?

If the theory of fighting evolution is correct, then the nose should have been flattened like that of Australopithecus, rather than gradually rising and rounded.

Moreover, the nose's ability to distinguish odors has not disappeared. Smell plays an important role in the division of territory and interaction in the animal kingdom.

The general requirements of evolution are not lost.

There must be some force that demands the evolution of the nose.

What is that?

Human interaction is not limited to the same sex, but more importantly between the opposite sex.

Modern research has shown that humans have invented many things for heterosexual emotional interactions. For example, human intimacy has shifted from back-to-back to front-facing interactions.

However, the scarcity of human numbers in the early days required the rapid establishment of affection between the opposite sex, so as to complete the task of human reproduction and maintain the development of the population more quickly.

Human communication between heterosexes has long been different from grooming between apes.

Frontal human interaction means facing each other with parts such as the soft abdomen, which means mutual trust between the two parties.

What are the normal behaviors of human interaction between heterosexes?

First of all, the point to see is the facial cleansing. In addition to drinking, human beings use water for cleaning. This should be one of the many complex emotional requirements developed by human Homo sapiens, and the increasing complexity of emotions will further promote the increase of brain capacity and the evolution of its structure.

Facial cleansing is also bad for the tall brow bones, which are naturally required to be low in the evolutionary process. The close action of the forehead of the opposite sex in humans also has the requirement of evolutionary low-level brow bone.

However, daily facial cleansing is beneficial for the evolution of the nose in the middle: the action of washing the face with both hands will invisibly form a massage squeeze on the sides of the nose, which will promote the growth of the nose.

Second, does looking at a tall nose hinder human interaction between heterosexes?

There is an intimate act of kissing between men and women, and human kissing may be due to the spitting behavior of the same kind. Spitting is common in the animal kingdom, but it gives it more emotional meaning among humans of the opposite sex.

A high nose does not pose an obstacle to the intimate act of kissing. The high nose pulls the eyes of men and women to a subtle distance when kissing, making it possible for men and women to make microscopic eye contact, and men and women who have experienced it should understand the subtlety. The gradual rapidity of breathing during kissing will not only promote the communion of hearts, but also speed up the pace of further emotional communication between men and women. Therefore, there is no reverse evolutionary requirement for the nose in human interactions between heterosexuals.

Third, are there any aesthetic requirements for the face in human interaction between the opposite sex?

Male instincts in the animal kingdom have evolved various means of attracting the opposite sex in appearance, such as the beautiful tail feathers of beautiful male peacocks.

For the human face, a tall and individual nose is in line with the requirements of biological evolution, as well as the requirements of interaction between people of the opposite sex.

That's all there is to it. For the 6 million years that have passed, all mysteries are arbitrary, and human beings are flipping through the book of nature in order to bring the past to a clear light.
