Hundreds of years ago, mankind finally entered the industrial age from the handicraft era. The advent of science and technology has brought new opportunities to mankind. It only took us more than 200 years to achieve great leaps again and again.
With the help of science and technology, people once only had to look up at the fantasy starry sky, which also allowed mankind to make a major breakthrough. With the help of science and technology, human beings got rid of the shackles of the earth’s gravity, walked into the starry sky, stood in space, and we saw a dark, cold and lonely universe.
The real universe in front of us is different from what the ancients imagined. In the ancients’ imagination, the universe should be very lively and beautiful, but what really appears in front of us is not like that. So far, we have not been there. Any shadow of extraterrestrial life is found in the universe. Solitude and silence are still the main theme of the universe.
Then there are no other planets of life in the universe except the earth? Scientists don’t think so. We must know that the vast scale of the universe is so large that we can’t imagine it. Whether it is on the scale of the universe or the age of the universe at 13.8 billion years, the existence of extraterrestrial life is basically inevitable. The reason why we have not Any discovery is mainly because the scale of the universe is too exaggerated, and the scientific and technological strength of human beings is still very weak, unable to carry out interstellar voyages and truly go out of the solar system to explore.
This is actually the same as the ancient people’s fantasy of standing on the seashore. I believe that people who lived by the sea thousands of years ago often stood on the seashore and watched the unseen ocean, and wondered if there would be others on the other side of the ocean. Human existence? However, since there was no advanced manufacturing technology and navigation technology at that time, it was impossible to truly explore the ocean, and it was naturally impossible to discover the existence of several other continents.
Human beings are now going out of the universe to look at the entire universe. It is the same as the ancients standing on the beach and looking at the entire ocean. We also dream about the existence of extraterrestrial life, but because of the inability to carry out interstellar navigation, we naturally cannot go to the depths of the universe to explore life. The presence.
Although humans have not yet been able to explore extraterrestrial life, it does not hinder our guesses about extraterrestrial life. In the eyes of scientists, life evolved from different planetary environments may be very different. Since living things have a common origin, they have many similarities in all aspects such as genes.
And alien life may be very different from earth life in terms of genes and other aspects. If there is alien life on the earth, it is believed that it is not difficult to find the huge difference through the comparison of all aspects. So is there any extraterrestrial life on earth? In this regard, scientists have no definite answer.
Although scientists have not determined whether there are extraterrestrial life on the earth, they still have some doubts about some special creatures, such as the mollusk octopus that we are all very familiar with.
I believe my friends are no strangers to octopuses. It is a kind of marine life. In the seas of different depths, there are shadows of octopuses. Even in the deep sea of several thousand meters, there are still some giant octopuses. Therefore, octopus occupies an important niche in the marine biological system. They seem weak and bully, but in fact, octopuses are also a hegemon in the ocean, and they can often defeat the strong with the weak.
As for the speculation that octopuses may be alien life, as early as 2015, Nobel laureate Sydney Brenner published a paper in the journal Nature, which stated that the octopus’s genes and other creatures on earth The genes are very different.
On March 13, 2018, the famous academic journal “Progress in Biophysics and Molecular Biology” published a paper with the title of “Causes of the Cambrian Explosion”. This is an academic paper jointly completed by 33 biologists. The article emphasizes the special features of octopuses. It also puts forward the same point as Sydney Brunner, that is, octopuses may not be the earth. Aboriginal people, but from outer space.
In the article, scientists speculate that an ice comet came to the earth with octopus seeds 570 million years ago. The octopus seeds took root in the ocean. Through more than 500 million years of evolution, the octopus’s Look like. Why do many scientists suspect that octopuses are not native to the earth, but come from space?
As we said earlier, different planetary environments will evolve different life forms. The creatures on the alien planet and the creatures on the earth will definitely be different in many aspects, because the original origin of the alien life is different from that of the earth life, so the octopus What are the fundamental differences from the millions of life on earth? Mainly reflected in the following aspects.
1. Octopus has three hearts
You heard that right, octopuses do have three hearts, which is very different from the creatures on earth. We all know that in the Earth’s biosphere, the more complex and advanced life has only one heart. This is because these organisms have a common origin, and there are many similarities along the evolutionary path.
In the Earth’s biosphere, only simple creatures like horseshoe crabs have three hearts. In addition, all complex and advanced creatures have only one heart. The octopus is a relatively advanced creature. If it is a native of the earth, it should theoretically have only one heart instead of three.
An octopus has three hearts, which naturally has many benefits for it. Just imagine, if humans have three hearts, then our physical fitness will be greatly improved. The heart is equivalent to the engine of the organism. The stronger the power, the viability of the organism will be. The stronger. The three hearts of octopus have their own functions, which can be said to have a clear division of labor.
2. The octopus has a developed brain
According to research, the octopus’s brain has more than 500 million neurons. In addition, it also has many unique sensory organs, which together with neurons form an alternative nervous system. In this way, the thinking ability of octopus far exceeds that of ordinary animals.
Moreover, the octopus’s brain also has two sets of memory systems, one system serves the brain, and the other system directly serves its many tentacles. Each of its tentacles is equivalent to an independent nervous system, so that the octopus can do one-hearted use. This is an ability that is against the sky. This ability is also very envied by humans. We must know that we must do two purposes with one mind. An easy thing.
Scientists have discovered through a lot of research that octopuses have the ability to think and are very smart mollusks. If a ranking is based on the wisdom of marine life, it is not the dolphins that rank first, but the strange-looking octopus. It is precisely because the octopus has a very high IQ that it can dominate the ocean.
3. The complexity of the octopus genome surpasses that of humans
You heard that right. Scientists have discovered through research that the complexity of the octopus genome has reached an incredible level. They have 33,638 protein codes, while humans have only about 21,000. A large number of protein codes also give octopuses the ability to quickly adapt to various complex environments, so they can survive more than 500 million years ago to the present.
Through the above three understandings, I believe that my friends can also see the difference of octopuses. If the future ocean will give birth to a kind of intelligent life, who has the highest probability? I believe that many scientists will think of octopuses. It does have many special features, especially the genetic information, which makes more and more scientists suspect that octopuses may be extraterrestrial life.
