Deep sea phobia is a type of phobia. When patients imagine, see or come into contact with the sea, big waves, marine life and other ocean-related things, they will have rapid breathing, rapid heartbeat, cold sweats, and trembling hands and feet. And tried to escape.
Then why is this? Let everyone follow the editor into human origin .
1. The origin of mankind!
When talking about the origin of human beings, we have to refer to the famous evolution theory . As an important theory of contemporary biology, its introduction has given us a more reasonable understanding of the origin and evolution of living things. At the same time, with the rapid development of bioscience technology , we can also find more information about the origin of human beings through the study of DNA gene molecular chains. However, there are actually several completely different hypotheses about how humans evolved. Among them, the most recognized hypothesis is the theory of evolution, which believes that we humans evolved from apes in ancient times.
Other hypotheses also have their own reasons. For example, the alien theory believes that humans came from outer space, and the existence of human civilization may be related to alien civilization. Some archaeological experts have discovered factors related to outer space from ancient Mayan ruins, but the connection between the Mayans and extraterrestrial civilization has never been established. But regarding the theory of evolution, some people have also put forward another more subversive hypothesis, which is the ocean theory, that is, the ocean is the birthplace of human beings, and our human ancestors are "water apes", a species that lives in Apes in the water are different from apes living on land in the theory of evolution. As we all know, more than 70% of the earth's area is occupied by sea water. You must know that the earliest living things, some single-celled organisms, appeared in the ocean.
In fact, some organisms on land came from the ocean and evolved from aquatic organisms to land organisms over a long period of time. According to Gondwana , eight million years ago, apes divided into two different evolutionary directions. One evolved into today's humans, and the other evolved into today's various apes. . It's just that we still haven't figured out how humans differentiated from ancient apes. The ocean theory assumes that some individuals among the apes at that time left the life in the trees and entered the world in order to seek a better living environment. the ocean. There is no doubt that this assumption has subverted many people's previous understanding of and .
Therefore, in order to adapt to the living environment in the water, they have evolved accordingly. For example, unlike the nose structure of most apes, our human nostrils look more hidden and open downward. . This structure well prevents water from pouring into the nostrils during underwater activities. Perhaps it is a characteristic that apes evolved to adapt to life in the water. In addition, just like aquatic creatures such as dolphins and walruses, they can regulate their own body temperature and carry out life activities normally in the ocean thanks to their subcutaneous fat layer.
This may be because some apes left their living environment in the trees and entered the ocean. In order to adapt to life in the water, they needed subcutaneous fat that could regulate their own body temperature. Then the hair on the skin surface faded, and a new evolution was achieved.
2. The self-protection mechanism formed during evolution
Human beings’ fear of the deep sea is probably inherited from their ancestors’ fear of the deep sea in the form of genes in ancient times, just like snakes.
Snake is the collective name for a large class of reptiles . There are more than 3,000 species on the earth and have an evolutionary history of more than 100 million years. Today's snakes are all small snakes. In ancient times, the largest snakes were ten. Many meters long, it is a very terrifying predator. But when the ancestors of mankind encountered this animal for the first time, they did not know its danger. Many accidents must have happened and they were bitten to death by snakes. And those who can escape from the snake's mouth will inevitably stay away from the snake out of fear.
Human beings are naturally afraid of snakes, which is different from the fear of tigers and leopards. Our fear of snakes comes from our genes. This is a special mechanism passed down to us by our ancestors through the lessons of blood and tears. "Fear of snakes" "It can keep us away from this animal and away from danger.
Perhaps the fear of the deep sea is because our ancestors saw something dangerous in ancient times.
