Chapter 2: Ancestral Ape
readx;?ā Humans and other primates, including chimpanzees, are not only similar in physical characteristics, but also in similar social behavior. Pen @ fun @ pavilion wWw. ļ½ļ½ļ½Uļ½Eć It is generally believed that this is mainly due to the fact that their brains are well developed, so they also behave in a more complex way than other animals.
Primates are mostly social animals. They live and move in groups. Its size varies depending on the species. In a group, there is an individual with an adult male who is the leader of the entire group.
There are also interactions between individual primate animals. The most notable is the activity of grooming the other party. They remove parasites, debris, etc., from their companions with each other. In addition, primate juveniles often play games with each other, either to understand their surroundings or to train strength, which often depends on strength to become leaders.
Primates are able to make sounds and communicate with each other. They use a series of shouts or movements of a certain part of their body to convey a message.
Primates generally have a "living area", which is a certain area of normal activity. Patrols are often carried out by members of groups around residential areas. Within the residential area, it is also divided into small areas according to the size of the group and the way in which food is obtained. The residential area often changes depending on the season. Some populations migrate to areas they frequent, called "core areas".
Primate babies are different from other animals in that they follow their mothers at birth and live entirely in the care of their mothers, snuggling up in their arms. Of course, motherhood behaves differently between different primates. Males of many primate species often act as parents for the baby, working together to care for and protect the baby.
An important social behavior of non-human primates is aggression. This behavior is generally performed through posture to intimidate the opponent, rather than through intense fighting. Wrestling is generally used only when fighting for leadership in the group. Primates have a strong hierarchy. Male leaders have a preference for food, a female, and a subordinate member. But when he is injured or sick, he risks losing that status.
Because primates are closely related to humans, their lifestyles may also be similar to those of the earliest humans. Therefore, it is of great help to scientists to study the ancestors of humans.
Whereas, among primates, chimpanzees are the animals that most resemble humans.
It is important to know that 60% of the DNA of humans and fruit flies is the same, and 80% of the DNA of humans and mice is the same. And 98.5% of the DNA of humans and chimpanzees is the same (the genes between two people are at most 1.5%, so chimpanzees are not much more different from humans than they are between two people). In fact, rh-positive blood types between humans and chimpanzees can be transfused to each other.)
The difference of just 1.5 per cent determines that one is outside the cage and one is inside the cage, one is hosting the Olympics and one is jumping around in a tree, one is studying Goldbach's conjecture, one is remarkable when it counts to nine, one can grow like Audrey Hepburn, one is covered in black hair, one talks about "all men are created equal", and one is tortured in a medical laboratory. Upright walking, complex language, science and art, philosophy and religion...... The root cause of these people's peculiarities can be traced back to the 1.5%. And what are the specific differences in the 1.5% that draw the line between chimpanzees and humans?
The only conclusion currently reached is that humans have 23 pairs of chromosomes, while chimpanzees have 24 pairs of chromosomes. But why there is such a big difference between 1 pair of chromosomes, scientists have not yet found out the answer. This is almost the realm of God. "
"Why, did the sages also believe in the existence of God?"
"Yes, you must know that the world without faith is prone to spiritual emptiness, but because of the high development of technology, a large part of the theological content in the past is now classified as science. In fact, according to Russell's History of Western Philosophy, science and theology together constitute all knowledge. Theology is a science that has not yet been defined. Therefore, although science is highly developed, compared to the universe, there is still a majority of unsolved things, so there is still room for theology. ā
The earliest Epiphyllium of the Pliocene (Ethiopia about 5.8 million ~ 5.2 million years ago) diverged from the Tugan Homo (chimpanzee) and is considered to be the earliest ancestor of humans.
Scientists have unearthed an incomplete skeleton of a female animal from 4.4 million years ago, consisting mainly of a toothed skull, arms, hands, pelvis, legs, and feet. It is nicknamed ARDI by scientists. Some of the features of the Archaeopteryx fossil skeleton are similar to very old great apes, while others are similar to those of later great apes that were closer to humans.
The fundamental difference between the Australopithecus, represented by the Archaeopteryx species, and the earliest humans is that humans were able to make tools, especially stone tools. Labor that begins with the manufacture of tools distinguishes man from all other animals, and labor creates man. Another major feature is that humans were able to walk upright, while the Archaeopteryx species were already able to walk upright, indicating that the separation had become smaller.
The time of the Pliocene period from about 5.33 million years ago to 2.59 million years ago, from the Archaeopteryx to the Pleistocene (about 2.59 million years ago), the fossils of apes are almost blank, and this period happens to be a critical period of evolution from apes to humans, which is called the "lost link". During this period, the first racial differentiation in human history took place.
I asked, "What does it mean to be racial, does it mean the classification of whites and blacks?"
Sage: "That's right. The first differentiation of the human race was the division of the white man from the progenitor species of the ape. ā
"So did they start with white skin?"
"In fact, white people, like all modern human ancestors, were covered with a large amount of hair at the time of the first differentiation, so they were not overexposed to ultraviolet rays, so the skin was white. Of course, it was only after cutting the hair and bathing that it was white, and at that time, judging from the hair, all the progenitors of the ape were black. ā
"So what evidence is there that white people were the first to divide into races?"
Sage: "First of all, let me tell you about the general division of the human race. ā
There are many ways in which the human race is divided into races in the world. Among them, the international common division is the four major races: Asians (yellow people), Caucasians (whites), Africans (blacks), and Oceanians (browns). Most of the low-caste population in China and Southeast Asia, as well as in India, belong to the Asian race, while people in Russia, including the vast majority of countries in Europe and the United States, belong to the Caucasian race. The vast majority of Africans belong to the African race. Most of them can be identified by skin color.
