What is the possibility of intelligent life under the sea? What have humans discovered today?

Chihiro replied, I think the possibility is zero.

Not long ago, I answered a similar question and asked why there is no civilization in the ocean. I start with the most advanced creature-mammals, and think that the reason why the ocean has no civilization is that there are too few mammals and the ocean is not suitable for mammals to survive. In order to adapt to the marine environment, a very small number of mammals have evolved for tens of millions of years, and finally become the only two mammals that we see completely living in the ocean-cetaceans and manatees. They spend a lot of time adjusting their body structure to adapt to the marine environment, and eventually become "half fish and half beast" strange animals, but they are getting farther and farther away from civilization.

The question this time is, what is the possibility of intelligent life under the sea? I think the reason is the same, or because the seabed is not suitable for mammals to survive.

Why am I always obsessed with mammals? Because mammals are the most advanced creatures in the history of the earth, and human beings, as the most intelligent creatures on the earth, are mammals. Even if there is another intelligent life in the world, it must be mammals, reptiles, birds, fish and low-level mollusks. They can't be intelligent creatures. They lack enough brain capacity and are born conscious, but live by pure biological instinct.

The seabed lacks oxygen and sunlight, and the water temperature is very low, food is scarce, and the pressure is huge. The creatures here are forced to turn themselves into all kinds of "ugly" monsters in order to survive. How can we have the opportunity to evolve into intelligent creatures by struggling with the harsh environment every day? Moreover, the limit diving depth of mammals is 3000 meters, and the longest diving time is 138 minutes, so mammals can't stay in the deep sea for a long time.

Many people think that the ocean is too vast and deep, and there must be many secrets that human beings don't know. There is even a saying on the Internet that human exploration of the ocean is less than 10%. I think these people's cognition is long out of date. At present, human beings have basically touched the ocean by using various submersibles and detectors, and the depth, topography and resources of the seabed are basically clear. In many places, humans have never gone down in person, and in fact, they don't need to go down in person.

In short, the harsh environment under the sea is enough to obliterate the possibility of the birth of any intelligent creature. I'd rather believe that there are extraterrestrial intelligent creatures than that there are intelligent creatures hidden under the sea.

I just came back from watching Neptune in DC, and when I saw this question, I was talking nonsense. What is the possibility of intelligent life under the sea? Maybe it's zero percent!

Some people say that compared with the exploration of space, we know very little about the seabed. The main possibility is that human beings want to get out of the earth and don't want to enter the seabed. Of course, this is a joke. The bottom of the sea is a cold, heavy and dreary world. Generally, underwater creatures will float slowly like ghosts, because this is the most labor-saving way. It is impossible to evolve intelligent life in such an environment. Most of them are driven by instinct like "zombies", devouring food, slowly floating and waiting for death.

The smarter and more civilized a species is, the higher its demand for energy. So it's only that small part that stands at the top of the food chain. The bottom of the sea is terrible, and there are few creatures. What can be used to support intelligent life?

If "intelligent life" is a human being or a more intelligent creature than human beings, the possibility of existence is zero, and there are no "underwater people" on the seabed; If it is an IQ animal like dolphins and whales, there are still many.

The topic is that I don't know much about evolution, so that there will be such a problem. From the perspective of biological evolution, it is all because of gene mutation, which is a random change influenced by the environment. Whether it can be passed down depends on whether the mutated gene can play a beneficial role in the survival of species, or at least it is harmless. Every creature has its own unique weapon to adapt to its own living environment. IQ is the greatest weapon of human beings, but not necessarily for other creatures. For example, if you meet a tiger in the wild, no matter how good your brain is, the tiger will kill you in minutes.

The ocean explored by humans so far accounts for less than 10% of the total ocean area, but humans can infer unexplored areas from the detected ones. Biology is defined as the aggregate of substances with the characteristics of reproduction, communication, activity and energy utilization. The definition of civilization is everything created by some biological activity, such as culture, science and technology, art and so on. According to these definitions and the scope of human observation, there is no "intelligent life" in the ocean that is similar to or beyond human beings. The characteristics of life on earth make them conflict with human beings once they exist, because the earth's resources are so limited, and human activities are still changing the marine environment and threatening it.

It is a fact that human beings have not observed another kind of "higher intelligent life" activity on the earth today, and will not observe it in the future.

First of all, the living ecological space under the sea limits the evolution of organisms, so it is impossible to evolve highly intelligent organisms. Humans and other creatures on land are creatures that gradually evolved from the ocean to the land. The continuous evolution of the body adapts to the living environment of land, and the living ecological space of land is better than water. In the world of the natural law of the survival of the fittest, the land chose the ancestors of human beings to become the only hegemon on the earth. In addition to their innate conditions, there are also some accidental conditions that enable human beings to evolve into highly intelligent creatures.

Gentleman's nature is the same, and goodness is empty of things. How to extract substances from the seabed?

Personally, I don't think there is any human civilization like undersea goods.
