【For example, why are we so obsessed with sugar and fat, knowing they are unhealthy but still eating them?】 【Why do other animals have specific estrus periods, but humans are full of sexual desire all the time?】 【Why do we need the so-called approval of others and always maintain a heart of gossiping about others?】 【Why do most creatures die when they lose their fertility, but humans are so attached to life?】 【Why do you yearn for poetry and distance? Do you like the feeling of traveling and running, but regret staying at home all day? 】 The video begins. He threw out several whys in succession. When seeing these questions. Many ancient people could not help but be substituted into it. Think about it
"Yes, why?" "Put it this way, it seems to be true......Compared to other beasts, humans are indeed very different" "Yes, my family once had raccoon slaves. The mating of raccoon slaves has fixed stages, but this has never been the case for us." "yearning to run......" Cheng Yaojin touched his big belly. I also suddenly realized it. After the world is settled. There has been peace for a long time. But he still wanted to gallop on his horse from time to time. in the past. He thought it was because he missed the days of fighting on the battlefield. But look now... Isn’t this a human instinct? "But so what?" "Could this mean that we are like monkeys?" Cheng Yaojin dismissed it. Tianmu: After raising questions. Opening up the viewers' minds and making them think about what is special about humans that are different from animals. Next, the video gets to the point.
【Various fossil evidence points to the earliest humans appearing in Africa】 【On the great plains of Africa, the most obvious feature that distinguishes humans from most animals is that they walk upright.】 【Walking upright is of extraordinary significance to humans. It is the golden key in the process of evolution, opening up an evolutionary direction that is completely different from that of most organisms, and laying the foundation for the basic form of modern humans.】 【In 1973, scientists discovered the fossil of an ancient ape later named Lucy. She was a 1 to 12-year-old ape from million years ago. Her complete and obvious arches showed that she could walk upright for a long time.】 【Because the appearance of the arch of the foot is to increase elasticity for walking upright and absorb shock to the body, otherwise a 100-meter sprint may cause concussion.】 【But the emergence of arches also makes the feet no longer suitable for gripping, and is no longer suitable for life in the trees.】 【At the same time, she evolved a wide pelvis to support the upper body and connect the trunk and lower limbs. She also evolved a 150 knee bone that was significantly larger than other creatures. It was also a product of shock absorption and shock absorption for walking upright. These traits all illustrate Lucy can walk upright for long periods of time and even run】 【So, what was the reason that forced our ancestors to leave the tree canopy millions of years ago and come to the ground to start walking upright? 】 In the sky. A piece of video material from later generations is given. It was an ancient ape fossil placed in a glass display case. Although it has experienced the corrosion of time. Many parts of this ancient ape fossil have been severely damaged. But judging from the only remaining body. It can be vaguely seen that she already possesses many human characteristics. Such as a wider pelvis and larger kneecaps. as well as. That complete arch! Suddenly. The ancients were dumbfounded! Ying Zheng was stunned for a moment:"There is really evidence?" Liu Che moved forward and looked at the sky with rapt attention:"It originated in Africa? Africa? Isn't that another continent besides China?" Cao Cao was shocked:"This It's too bizarre!" Liu Bei was stunned and asked:"Could it be that we are really transformed from monkeys?" Li Er noticed the name:"It turns out that it is not a monkey, but an ancient ape? Ape from ancient times?" Old Zhu Dun My scalp feels numb! Now the evidence has been revealed! Wouldn't that mean......it is true? "Man is the supreme being of heaven and earth, how is this possible!"
However, the inherent concept in his heart still made it difficult for him to accept it for a while. On the side, Zhu Biao watched it with gusto. "Walk upright?" "What caused the ancient apes to start walking upright?" Canopy: 【To study the reasons why human ancestors walked upright, we must of course understand the natural environment at that time.】 【When we open the map, we can see that the place where Lucy was found has a very obvious landform feature, which is the Great Rift Valley of East Africa.】 【About 10 million years ago, the original African continent was a whole, with dense forests and luxuriant water and grass. Various animals, including primate monkeys and apes, collected abundant fruits and leaves in the forest, and occasionally ate some trees. Insects or small animals on】 【Because most large carnivores cannot climb trees, life in trees is much safer for ancient apes.】 【However, when the Great Rift Valley was formed, the African forest was cut in half. Later, coupled with global climate change, glacial activity intensified, the climate became colder, and tropical plants were gradually replaced by deciduous forests and grasslands, coupled with nearby geological movements As a result, mountains and valleys appeared at the same time. The moist air brought by the trade winds from the west (dabj) was blocked by the mountains. The east side of the rift valley became increasingly dry, and the formerly dense forests gradually turned into grasslands.】 【The ancient apes that were originally adapted to life in the trees were blocked by the mountains and ravines of the Rift Valley, and stayed on the east side of the Rift Valley together with many other animals. That is to say, the ancient apes that originally lived in the trees had no trees to climb and were forced to come to the Rift Valley. The earth adapts to the dangerous and barren life on earth.】 【At this time, evolutionary pressure began to appear, because they had to detect the attack of food animals in advance to have a higher probability of escaping. They had to stand up to see beyond the grass. 】 In the sky The frequency simulates the changes in the natural environment at that time through CG animation. Condensing millions of years of geological changes into just a dozen seconds. The vicissitudes of the sea are like a thousand years at a glance. The earth cracked under the movement of tectonic plates, forming a huge rift valley. Forests degraded due to drought and became grasslands. On the endless grassland. One by one, the ancient apes stood up. Try to keep your sight beyond the grass. Because there is no protection of the forest. They need to protect themselves this way. Come and detect threats from predators in advance 【The harsh environment certainly killed most of the ancient apes, but it still allowed a group of ancient apes that could adapt to upright movement to survive.】 【In fact, there is a greater advantage about walking upright. This researcher has specially conducted experiments.】 【Let people and chimpanzees of the same weight run the same distance on a treadmill while wearing masks. Side chamber oxygen consumption】
【The results of the oxygen consumption test are amazing. The energy required for humans to walk upright for a specific distance is only 1/4 of the energy consumed by gorilla 4 walking.】 【In other words, with the same amount of energy intake, you can walk much further by walking upright, and you have a greater chance of finding your next meal on the prairie.】 【You must know that in a relatively harsh natural environment, even if you can save a little bit more energy, that is the hope of continued survival. This is one of the reasons why we humans cannot resist foods containing high calories.】 【On the barren African grasslands, if you can encounter sugary things or meaty nuts containing a lot of fat, what are you waiting for? Take it in quickly, this is energy, you can live longer】 【The evolutionary result of this is that when the human taste system accepts sugar, the brain directly secretes dopamine, allowing the individual to remember that this is a beautiful thing. The same is true for oils. By the same token, the digestive system has also evolved. Allowing the ancient apes that fell to the ground to digest more meat and fat】 【Ingesting more energy, at the same time, walking upright saved energy, allowing these human ancestors to have more leisure to reproduce or interact with group members, and develop social skills】 【Complex things evolved from the simplest reasons. Perhaps the main reason for the evolution from apes to humans was because it could save energy. Coupled with the need to hunt, escape and identify directions, humans finally stood up permanently!】 【We gave up the flexible soles of our feet to provide shock absorption for running. In order to move more steadily, our lower limbs began to become thicker, our knees began to grow larger, and our pelvis also began to increase to support the weight of the upper body. These structural changes require more More energy and nutritional support, especially calcium. Walking and standing upright for a long time also requires a greater sense of balance. At the same time, it also stimulates the evolution of the brain to a certain extent. 】 Although it is still difficult to accept. But after this large section of the marquee was shown. Everyone has to admit it. This explanation about walking upright. What you say makes so much sense! Because of changes in the natural environment. Let the original forest become a grassland. The ancient apes were forced to live on the ground. And because of the threat of predators. The ancient ape had to stand up. Lift your body above the grass. Have a longer view to spot danger. at the same time. After arriving on the ground. The food types of ancient apes are further enriched. The digestive system evolved. Can digest more meat and fat. And after standing up. The hands of the ancient ape are further liberated. Plus the food you eat contains more energy. (To read exciting novels, go to Feilu Novel Network!) And walking upright consumes less energy.
This gives the ancient apes more time to reproduce, interact with the group, and develop social skills. Although the ancients lacked knowledge compared to modern times. But that doesn't mean they are ignorant. So after being exposed to this new perspective. Although it is difficult to accept it for a while. But it’s hard to argue with that. The Tang Dynasty plane. Li Er couldn't help but ask "Gentlemen, what do you think?" "Could it be that we humans really evolved from ancient apes?" As soon as these words came out, all the ministers looked at each other. Say yes.......[] This goes against what they have always known. But that’s not the case, right?...... Reasonable and well-founded. And there's even fossil evidence. How to refute? The ministers did not speak. I don't even know how to answer. But in fact this kind of non-answer. Disguised is also an answer. then. Li Er was silent. Although this result is not good for them. not at allWhat substantive impact. But what I had always believed in was shattered....... This feeling...... It always feels weird. The Ming Dynasty plane. Compared with Li Er and others, they gradually tended to recognize it.
Lao Zhu is undoubtedly more stubborn "What a joke, what a big joke" "Did humans evolve from a group of apes?" "How outrageous is this?" "It’s not like we haven’t seen monkeys before" "Why, since they all came from apes, why didn't they evolve? Still living in trees?" "Why are they covered in hair, while we are bald?" Lao Zhu still chose not to believe it. And just like what he said, aren't there monkeys now? And the biggest thing is hair! Since we are said to be monkeys, what about our hair? It 's not just Lao Zhu..At this time. Many people also have the same question. "Since we are transformed into monkeys, why are monkeys covered in hair? And we only have a little bit of hair such as hair and eyebrows?" "That’s right, this is obviously nonsense! It doesn’t look like it at all!" "Unless you can give a valid reason to explain why we don’t have hair like apes, then I will believe it!" "That’s right!" The biggest difference between apes and humans. At first glance, there is no doubt that the hair all over the body. If walking upright can be explained, then what is the explanation for the hair on the body? Coincidentally. The video is just right. That’s all I have to say. Tianmu: 【There is another obvious difference between us and other non-upright walking primates, and that is hair.】 【Most of our skin is naked, and we have taken off the thick hair all over the body, leaving only local areas. Why is this?】 【It turns out that this body of hair can not only keep heat and lock energy, prevent sunburn, resist mosquito infestation, and prevent scratches and infections from thorns in the bushes, but can also camouflage in the environment. After all, a naked body is too much in the wild. It's obvious, so why do humans give up this treasure?】 【The answer is only two words - heat dissipation】 【We can see many fast animals in nature, such as cheetahs, antelopes, ostriches, etc. They are very fast, but! Most of them can only cover fairly limited distances】
【But humans are different. Humans are the only animals that can run ultra-long distances continuously such as marathons.】 【Compared with most animals of the same size, human running speed is not fast, and the explosive power of sprinting is very poor. However, there are no animals that can run for several hours continuously or complete a marathon of more than 40 kilometers in one go - many People would say that horses can do it, but without human support, it is very difficult for horses to replenish enough energy to complete such a long-distance run.】 【The energy-saving advantage of walking upright allows us to easily obtain enough energy reserves to complete such long-distance treks. After losing hair, humans have become the most capable creatures among all animals.】 【Imagine that humans have just come down from the trees. The weak apes have no hunting experience and run slowly. Since their brains have not yet begun to evolve significantly, they are not smarter than other animals, so they have no hunting skills. Then when they want to hunt, What will happen?】 【I think it's probably just running towards the prey slowly and stupidly.】 【For herbivorous prey, when you see a guy like this that doesn't attack, hide, or set traps, just jump away. Anyway, it can't run as fast as me.】 【But primitive humans will not give up and continue to run towards the prey. After all, in their simplest thoughts, if they do not catch up with the prey, they will starve to death.】 【To this day, indigenous people in America and other places will chase a deer for a day and a night without changing people, drinking water, or resting in the middle. This also proves that this hunting method is the most primitive instinct.】 【That's what evolution is】 【Those hairy ape-men fell on the way to hunt because of their poor heat dissipation.】 【The sparsely haired ape-man survived】 【In this way, from generation to generation, year by year, apes who are better at running and have less hair have reproduced. After millions of years, what is left is us who have lost our hair.】 【At the same time, this also explains why people who have been sitting in the office for a long time will have various physical problems. If you stay at home for a few days, you will feel decadent and always want to run out to the wild to relax. It also explains why you should have appropriate exercise every day. Running can keep you healthy. 】 When seeing this explanation about why apes have hair and humans have no hair. The Ming Dynasty plane. Lao Zhu was completely stunned! And at the same time. Ancient people from other time and space. They were all dumbfounded!.
