The evolutionary journey of human body parts and abilities

The evolutionary journey of human body parts and abilities

Do you know why our hair stands on end in fear and cold? Do you know why people who take part in speech contests start taking classes before they go on stage? Why does another person start repeating this process when he sees one person taking a nap? Why do we walk on two legs? When and how do we find our brain, spinal cord, feet, hands, eyes, nose, lungs, thumb, voice and sexual function?
Let’s find the answers to these questions in the evolutionary journey of man.
۔

Four thousand million years ago today, our earth was a fiery ball of fire. There were clouds of acid dust in the air. Lightning flashes in these clouds combine to form a special type of molecule in the atom. According to experts, somewhere deep in the ocean, these molecules managed to organize themselves in the form of organic compounds. Seawater now contained a variety of chemical and organic compounds. These compounds and chemicals succeeded in coming into being in the form of the first and simplest cell through the genetic material under the influence of light, electricity and pressure.
۔

Genes began exchanging chemical commands and information. The first cell divides 3.5 billion years ago. They were the first living creatures in the world. This cell was the ancestor of nine million species of living things, including every human being, every animal, every bird, every tree.
۔

Genes were responsible for the distribution and distribution of these cells. For two billion years, these simplest single-celled organisms were the only living creatures on Earth. The two cells then merged. Their genes coexist. This co-cell divides. The genes of the newly formed cell were inherited from two cells, the parents, rather than one cell. The accident is considered to be the world’s first “sex” act. Sex introduced diversity into living things. Mutations in genes began to occur. Different types of cells began to form. Different kinds of living things began to come into being. One of which was our test.
۔

Five hundred and fifty million years ago, our ancestor was in the shape of a sea turtle. The males and females of this creature were different. They had children through sex. The reunion of boy and girl started from here. However, it was very difficult to find a sex partner for yourself at that time. Because not all living things at that time had eyes. That is, everyone was blind.
۔

These were our perks in the dark sea. Who first began to see. Nature’s most perfect invention began to take place. By mutating in a part of the skin cells near the front end of the tortoise-like creature, we began to be able to distinguish between darkness and light. Now it was relatively easy for us to hunt and avoid predators. We lived longer now. And had more children. Soon the number of our first eye-shaped perforations exceeded that of all living things.
۔

Through natural selection, these perforated organs began to take on the shape of full eyes. Now we could see the world around us. And trying to understand it. Behind our eyes, our nerve cells begin to gather in a clump. In the beginning, they were as big as the tip of a pen. Today it is the most mysterious and complex organ of nature. Five hundred and twenty-five million years ago, it was the first brain of any living thing. Our body consisted of head, torso and tail. That tail is in the form of our backbone today.
۔

Five hundred and twenty-five million years ago, we became a small fish-like creature called the Milo Conjunctiva. Our brains were able to make simple decisions. Even so, owning one is still beyond the reach of the average person. Ninety-nine percent of all living things are now extinct. Three hundred and seventy-five million years ago, our jaws and teeth were formed. Our body was strong and big. Now we were one foot tall fish-like creatures. But there were stronger creatures than us. From which protection was necessary. I had to wade through muddy water to escape their attacks. There was not enough oxygen. This water was also toxic to us. There were more changes in our body. Our lungs began to form. We started breathing.

Now our ancestors, Aktio Stega, could tell the difference between swallowing water and swallowing air. Both the lungs and the gills had worked. We don’t have flowers today. But the procedure is the same. Three hundred and sixty-five million years ago, our ancestors pulled their heads out of the water. Outside paradise scenes were waiting for us. Our ancestor, Tiktalak, came out of the sea to build a new world.
۔
Three hundred and forty million years ago, our skin could not withstand the heat of the sun. Our soft skin and soft claws began to harden. Our nails began to grow. Now we had a lizard-like creature called a pink cassava. We had learned to live on land. Our eggs were now produced in a hard membrane. It was not possible for our males to lay eggs inside a hard membrane. We solved this problem through internal fertilization. Males and females now had regular sexual intercourse in the same way. What we have been doing to this day. This sexual act has guaranteed the survival of our generation ever since.
۔
Kasanario is the first successful land creature. Who carried their own weight. Used to breathe Had sex Used to see Used to smell Used to listen And tried to understand by feeling. His brain was developing. Our ancestors were getting smarter.
۔
Life has been evolving. New species kept emerging. The competition for food began among the animals. Two hundred and eighty million years ago, our jaw muscles began to strengthen. Now they could easily hunt for more food. Could fight dangerous predators. Could save themselves We could easily eat more meat. Our size started to increase a lot. Podosar who used to hunt us. Now they were hiding from us. We were very excited at that time. We used to open our mouths with scary sounds to scare other creatures.
۔
The world was devastated by the eruption of magma in Siberia. Trees and plants burned to ashes. Plant eaters began to disappear. Meat eaters are also at risk. Ninety-five percent of the species became extinct. A few survived. One was our ancestors and the other was the ancestors of dinosaurs.
۔
Twenty-two million years ago, we were as big as a cat. Before Siberian eruption, we were like a giant lizard. But we were not alone. We also had dinosaur pigs. Which evolved from small reptiles that survived the Great Depression. He was now ahead of us in the race for life.
۔
Sixty-six million years ago, we were in grave danger of extinction. The giant dinosaur hunter was after our lives. The principles of nature’s choice saved us. We kept getting smaller in size. We became as small as two-inch-long rats. Lived underground during the day. They used to go out hunting at night. The hairs of our bodies became like thorns. Through which we also absorbed oxygen. And in times of danger, they used to defend themselves with these thorns. Even today, if we feel cold or scared, our hair stands on end. That’s weird.
۔
Our senses became sharper. Now we could soon see or hear our enemy. The factory of complex ideas inside the brain became part of what was called the car tax. Which began to help us understand and cope with the situation. This part of the brain enables us today to dream, think, create, organize and communicate.
۔
Of course the dinosaurs forced us to evolve. We stopped laying eggs to protect our newborns from dinosaurs. Now the eggs became babies in the womb of the female. And so we started giving birth to children. Instead of finding food for themselves, she started breastfeeding them. Sweet glands turned into memory glands. It was the beginning of a new family. Mamalia family of more than four thousand species. This includes us, from small rats to large whales.
۔
Sixty-five million years ago, a dinosaur became extinct when a giant meteor struck the world near Mexico. The accident gave the small mammal a chance to flourish. Sixty-four million years ago, our squirrel-like ancestors ate insects. Their size had now increased to six inches. Mammals became the dominant creatures of the world. They were now spread all over the world.
۔
Sixty million years ago, trees began to bear fruit. The fruit was full of energy, delicious and dear to our hearts. You had to climb trees to get them. Fifty-six million years ago, our ancestors learned to climb trees. They could jump from one tree to another. Our feet and hands became long and flexible. Our tails were used to maintain our balance and support the tree branches. Primates, a group of mammals’ first mammals, called Atyraine lusters.
۔
For the next ten years, the world began to change once again. Forests were destroyed in the face of extreme temperatures. It became difficult to get food. Now we had to climb bigger trees. Our tails became longer and more flexible. Our thighs became stronger. Our arms got longer. The grip of our hand began to tighten. Now with their help we could swing with the twigs.

۔
The collision of the Arabian and African plates beneath the earth created the East African Rift Valley. New mountains appeared on the earth’s surface. Vapors from the sea became obstacles in the way of the winds. Due to the lack of rains, the forests began to turn into deserts. It became difficult to get food. Four and a half million years ago, our very existence was in grave danger. Our ancestor Primates once again succeeded in fighting nature.
۔
We were now four feet tall and weighed eighty pounds called “Orthopedic Remedies.” Our brain was as big as a stone. We could stand with twigs. He could walk with them. But to get more food we need to walk on two legs. Four and a half million years ago, we took the first step on two feet. Walking on two feet we reached the food. And the front hands were free. We could easily catch something with it. Orthopedics began to specialize in copying and learning. For the next long time we were able to move more and faster. Finding shade and food became easier. But the birth of a child began to be difficult. Three hundred and twenty million years ago we began to give birth to short-lived frail children. Now it was our responsibility to protect and nurture them.
۔
Three and a half million years ago, our ancestors became the Australopithecus. Our brain had developed further. Now we walked on two legs all the time. But we had a hard time avoiding predators. Two and a half million years ago, our facial muscles began to shrink through mutations. It benefited the brain. There was more room for the brain than ever before. The size of the brain began to increase.
۔
Now a new creature, Homo habilis, had evolved. With a developing brain, strong muscles and a strong body, it was the first living thing in human form. Homo habilis lived alone. They ate whatever they could find. Homo habels were the first to use stone as a tool. Now our future was in our own hands. We were able to hunt more. Protected themselves from predators. He used to fight with his relatives. In times of trouble and danger, Karkhadar would open his mouth with a voice. This frightened our opponents and gave the body and brain extra energy in the form of more oxygen. Even today, people who take part in trouble or speech contests start taking classes before going on stage. When a person takes Jamai, the opponent also starts repeating this action unintentionally. It is inherited from Homo habilis. According to experts, they also used bones as tools. Our thumb was now able to hold our grip on the tools firmly. Today we can hold a pen because of this ability. Can fly And the sky can form cracks.
۔
Homo erectus was born from Homo habils 1.8 million years ago. Now we hunted with our companions. They used to exhaust the prey. Sweat was beginning to help maintain our body temperature. Bent shoulders and strong thighs (the back part that made it possible for us to shrink, spread and move forward) helped us to be able to hunt.
۔
Lightning strikes were also first controlled by homoeurites. Now the great power of nature was at our disposal for light and salvation. Our families used to gather around the bonfire to escape the scary darkness. They used to distribute food among themselves. This is where the tradition of first burning meat and eating it began. Now we had to use less force on our jaws. The last teeth in our jaws were now useless. Forty-three percent of humans today do not have these teeth at all. With this process, our brain began to develop further. After cooking, our brain size increased by 50%.
۔
We started trying to talk to each other. Two hundred thousand years ago, our lynx (soundbox) began to slide upwards. Now we could make different sounds. Could talk to each other They could warn each other of the danger. The ability to communicate proved to be the last revolutionary step in our journey that gave birth to the human race of our generation. Homo sapiens, the self-proclaimed noble creatures who call themselves the noblest of creatures, have the most advanced brains of any living thing in the world, and are endowed with wonderful abilities such as speed, tools, speech, and intellect. Settled the continents. If there had not been a small mutation anywhere in this journey of billions of years, or if one of our ancestors had lost to nature, we would certainly not be here today. This would be our interesting story.
