Why do you think mankind is better than other animals? The answer may be due to his thinking ability or intelligence. It is human intellect that sets him apart from all other creatures. Where all other creatures on earth are simply struggling to survive, humans have developed their own language and civilization. He has subdued the world through the invention of all the extraordinary technologies. Now they are dreaming of crossing the earth and conquering space.
Why only people could do it? Why couldn't other animals? Because humans have a much larger brain than other animals. Not only modern humans or Homo sapiens, but also other primitive human beings had this remarkable feature. While the average brain size of a mammal weighing 60 kg is only 200 cubic centimeters, two million years ago the average human brain averaged 600 cubic centimeters and the average human brain averaged 1,200-1,400 cubic centimeters.
When all the other creatures in the world are happily at peace with their tiny brains, a big thing is hurriedly placed around the human neck, is that a good thing? You might be thinking, a big brain in proportion to the body means when the intelligence is high, then it is a very good feature. In fact, the matter was not so simple. Mankind had to pay a good price for this big brain. The human race is not just Homo sapiens. Other primitive human species have also been mentioned. Let's see what kind of trouble this object brought to mankind?
Carrying a huge brain in a large skull is quite a hassle for the body. Moreover, it is not easy to provide energy for this. Although it is two or three percent of the body in terms of weight, it consumes twenty-five percent of the body's energy during rest, whereas an app spends only eight percent of its energy on the back of the brain during rest. Primitive humans compensated for this in two ways: First, they had to run harder than other animals in search of food. Second, their muscles have also become relatively weak.
Much like the government cutting budgets in the defense sector and increasing spending in the education sector, people also began to power neurons by reducing the power supply in its biceps. This is not exactly an admirable strategy to survive on earth. Because a chimpanzee may lose an argument with a human, but this animal can easily tear a human to pieces.
You might say, what's in it? Now our big brain is working well. Thanks to this, we have now built a car that can run faster than a chimpanzee. And what is the need to wrestle with him? We can shoot him from a distance. But this gun or car came that day, the human neural network has come to this stage today to be rich. For more than two million years before that, with this brain, people have not been able to make anything more than steal some rocks and make eye sticks.
Another notable feature of human beings is that they move completely straight on two legs. While there were many positive aspects to it, there were also several negative aspects. Women in particular face a number of obstacles. The human buttocks become narrower than those of other animals as they adapt to the straight path, resulting in a narrowing of the women's birth-canal, while the baby's head grows larger. All in all, the birth rate rises abnormally.
Mothers who gave birth to relatively immature children then began to live longer. So over time, according to the laws of natural selection, human babies begin to be born immature. This is why you will see that where a hen learns to live independently two weeks after birth, a human baby needs care and education year after year. As a result, another thing has happened - the family has been formed to take care of the child, the society has come from the family. And since the human baby is born immature, he can be raised at will. Every human being can be made a proper social animal.
Today we think that this huge brain, the use of machinery, the extraordinary ability to learn something and the complex social system have brought a huge benefit to mankind. Now it seems normal, because all this has made man the most powerful animal in the world. But these were millions of years ago. But man was just a weak animal then. They had no superiority over other animals. They spent their days in fear, when an animal attacked and sat down.
Millions of years ago, people rarely succeeded in large prey. They survived largely on fruit or plant foods. He also used to hunt some small animals. Sometimes people would take the rest of their prey after eating a large predator. An intriguing piece of information can be found in this regard - according to researchers, the primitive people used the core of their rocky weapons to break the bones of an animal into bones.
To find out. Wondering, maybe why bone marrow?
Think about the time to get the answer. Suppose a lion hunts a giraffe. Humans can no longer afford to quarrel with lions over food. So he ate his prey with great ease. This time it is the turn of hyenas and jackals. They will devour the rest of the prey left by the lion. People do not have the courage to go with them. If there is anything left after they have eaten, it is the turn of the people. At that time, if the bones were removed from what was left, it did not seem that there would be anything left, so people tried to eat as much as possible.
These issues help to understand the psychology of today's people. For a time before very recently mankind was in the middle of the food chain. He used to hunt small animals. Occasionally he would become a victim of large animals. According to researchers, some species of mankind began to be successful in large prey from four million years ago. And millions of years ago, when with the rise of the present man or Homo sapiens, man moved to the very top of the food chain. People become very strong in a hurry.
Other animals that were at the top of the pyramid, such as lions, sharks, etc., came much slower at this stage. They have become stronger in the evolution of millions of years. So the ecology has adapted to them. For example, while lions have become more fierce over time, deer have learned to run faster, hyenas have become more cooperative, and rhinos have become more grumpy. Everyone has created a balance in nature.
But according to researchers, humans have risen to the top so quickly that ecology has not been able to adapt. The biggest thing is that man himself could not adapt to his newly acquired abilities. The previous strong creatures were full of self-confidence and pride. The glorious glory of millions of years has brought them this glory. But people didn’t get it. They have not yet become confident; His condition is vulnerable, like a frightened dictator.
That is why people have become so terrible and cruel. They are becoming a kind of threat to the whole nature. This rapid rise of human power is the cause of many destructive wars, natural disasters, and ecological catastrophes. The future of the whole world seems to be threatened by their actions. And is this large human brain mainly responsible for all this?
