Earth is a beautiful blue planet with rich life forms. In addition to land life, there is also marine and subterranean life. However, only intelligent humans were born on earth and slowly developed into human civilization. So a friend raised this question: why didn't the ocean, which is 71% of the Earth's surface area, give rise to civilization, but the land gave birth to human civilization?
Earth's ocean area makes up 71%, while land area makes up only 29%. Additionally, life on earth is carbon-based life and cannot be separated from water. For life on earth, water is the main source of life. source of life. Scientists have also discovered through archaeological research that land creatures on earth may have evolved from sea creatures. The first place where life originatedto have been in the ocean. Later, some life left the ocean and developed on land, and then there was land. .biology.
The types of marine life may be richer than those on land, so why didn't civilization originate in the ocean? To unravel this answer, you need to have a general understanding of the formation of intelligent life and civilization. There are tens of millions of species of life on Earth, why have only humans ultimately evolved into intelligent life? This is not a coincidence, but a choice of nature.
The main difference between intelligent life and ordinary life is the brain. The reason why humans have become an intelligent civilization is that the brain continues to evolve and develop, far surpassing that of other creatures. If the brain wants to evolve, it cannot do without walking upright. It's when the singPrimitives came down from the trees and started trying to walk upright as the brain evolved and developed rapidly and transformed into humans.
It is basically impossible for marine life to walk upright. Although some sea creatures have limbs, they walk on their bellies. This may be linked to the ocean's living environment. Second, the development of civilization cannot be separated from energy, and an important condition for the birth of civilization is that there is energy. Without energy, there will be no rapid development of civilization.
Although the ocean is also rich in energy, it is extremely difficult to exploit it. Even in modern times, with advanced technology, there is very little ocean energy that can be harnessed. Energy in the deep sea is difficult to extract and use, but energy on land is different: it is easier to extract and use. Imagenose intelligent life which has just entered civilization. They do not have advanced and developed technology and can only use primitive methods to extract and use energy. In this case, only earth energy can meet the initial development of civilization.
Another important energy source on land is solar energy, which is not available in the ocean. The land is protected by solar energy and is rich in plants that provide abundant food. Only intelligent life can live on earth. Only by not starving can we slowly develop. Solar energy is a very important source of energy for humans. It can improve the body's fitness, provide various nutrients, and make humans more intelligent.
It is difficult to get solar energy from water. Not only is there no solar power, but there is alsot few other energy sources that can be used without energy, how can civilization develop? From the beginning of human civilization to the present, the most widely used is chemical energy, which is inseparable from the early development of civilization, and the most important energy source among chemical energy is fire.
Scientists once said that the birth of fire is an important symbol of human beings' true progress toward civilization. With fire, you can eat cooked food, which can make the human brain and body develop better, and can give the brain It provides better nutrition to the human body and makes humans more and more intelligent.
With fire, human beings do not need to be exposed to cold and can survive in the cold of winter. Only then can human civilization develop rapidly. Fire can alsocan effectively block wild beasts, and most wild beasts are afraid of fire. Fire, an important source of energy, can only be used on earth. It can be seen that the birth of intelligent life must meet many conditions, and most of these conditions can only appear on earth.
So even though the first life on land may have originated in the ocean and there may be more types of creatures in the ocean than on land, if you want to evolve from life to intelligent life and develop enter into civilization, only terrestrial creatures can. Through this example, we can also think of the extraterrestrial life and civilization that scientists are looking for.
Scientists have no doubt about the existence of extraterrestrial life and extraterrestrial civilization, but extraterrestrial life is also divided into ordinary life and intelligent life. Ordinary life can exist routinelyent in the universe, and some planets with harsh environments can also be born. However, smart life has higher environmental requirements. Only planets that meet several conditions can give rise to intelligent life and develop step by step.
If an alien planet is to give rise to an extraterrestrial civilization, there is a high probability that it will be born on land and not in the ocean, although the extraterrestrial civilization may be completely different from the civilization human. Life forms, but if they want to be born, evolve and become intelligent life, the land has more advantages than the ocean. Therefore, when scientists search for extraterrestrial civilizations, they always choose to search for terrestrial planets similar to Earth. This is not unreasonable.
Perhaps many friends will think of sea creatures as ifrein and think it's not intelligent life in the ocean? In fact, modern science has only seen mermaids in some literary documents, but has not discovered them in reality. Some historical records contain traces of mermaids, but these mermaids are not mermaids like everyone imagines, nor do they look like humans. They were also hunted by humans in ancient times. beings.
Guys, what do you think? Everyone is welcome to leave a message below to discuss it and express their own thoughts and opinions.
From the perspective of Earth's development, only humans have created civilization. Humans are earthly creatures. Can aquatic creatures create civilization like humans? The latest hit film "Aquaman" tells the story of a group of people who have the ability to survive underthe sea, but which are still considered a branch of humanity. In fact, this question is worth thinking about, because only by thinking can we find out that aquatic organisms are not a civilization can be formed.
First of all, we need to think about the body structure of aquatic creatures. In order to be able to move freely in water, the bodies of most aquatic creatures are streamlined, as this can occur. reduce the pain of swimming in water resistance. In this case, they will not be able to develop hands capable of making and using tools like humans. This is one of the biggest differences between humans and other species, and it is also an important reason for the formation of humans. civilization.
Although some marine molluscs have limbs that can serve as human hands, at the current stage their evolution is still in progress.ore at a low stage,Their members are not capable of making tools. Another reason humans can form a civilization is because they eventually learned how to use fire and produce it. The use of fire allowed humans to break the habit of eating hair and drinking blood, which was an important feature of early civilization.
However, it is impossible for aquatic creatures living in the ocean to use fire, so they are unlikely to use fire for cooking, metallurgy, etc. as humans do,Nor that Humans may have used fire to start the first and second industrial revolutions. Therefore, if aquatic organisms want to create civilization, they must exceed the limits of fire in water, otherwise it will be difficult to develop civilization. Humanity has entered the electrical ageric since the industrial era. The most important feature is that electricity has been widely used.
It is obviously impossible to use electricity on the seabed. Although creatures such as electric eels can hunt by electric shock, this method of electrification is fundamentally different from humans' use of electricity.
