Octopus is a very common creature in the ocean. People who eat it by "cooking, grilling, frying" or other methods may not have seen a live octopus with their own eyes, but they are deeply impressed by its taste and texture.

However, the strange appearance of the octopus also makes it a "psychological shadow" for many people. For example, the image of the terrifying old ruler "Lord of the Deep Space Star Sea" in the Cthulhu Mythos looks like a giant octopus, or the mysterious alien creature in "Europa Report" also looks like a giant octopus. Glowing octopus.

It can be seen that many aliens in human imagination look very similar to octopuses. After a long period of research, some scientists believe that the octopus may not really be a "native fish" on the earth, but that it should come from aliens. What is going on? Is there really something special about octopus? Next, let us walk into the past and present life of "Brother Squidward".

If you ask everyone where life on earth came from, then most people will say that it should have evolved from various substances forming cells. It is true that most people agree with this view, but the history of the earth is long and long. The time from the birth of us humans to the present may only account for "one second", so will the origin of life on earth come from extraterrestrials? Woolen cloth?

In 2018, such a controversial article appeared in the famous journal "Progress in Biophysics and Molecular Biology". This article mainly discussed the causes of the Cambrian explosion of life. First, let’s take a look at what the Cambrian explosion of life was.

This event has been called an "unsolved mystery" of paleontology. It mainly refers to the sudden explosive growth of life on earth during the Cambrian period 530 million years ago. Their forms are even more diverse, such as arthropods, brachiopods, chordates, etc. It is no exaggeration to say that the phyla, orders, families, genera and species in the animal kingdom were clearly differentiated during this period.

According to Darwin’s theory of evolution, the evolution of species requires individual mutations and long-term accumulation. The sudden appearance and leapfrog evolution of organisms in the Cambrian period is difficult to explain. Even Darwin himself said that this may become a Strong evidence against evolution.

This article puts forward such a view: "The reason for the Cambrian explosion of species is that alien space meteorites brought living species into the earth." They believe that meteorites that must have carried the seeds of life entered the earth by chance and were eventually hatched in a suitable environment. The most representative creature among them is the octopus we are going to talk about next.

It can be seen that if the hypothesis of this Cambrian biological explosion is true, then the fact that octopuses are alien creatures has been confirmed. When we look at the research information on octopus, we will find that it is not "nonsense" to regard it as a representative of alien creatures, because it is indeed too special.

This particularity is reflected in many aspects such as body structure, learning and imitation abilities, and even the ability to edit RNA by oneself. Obviously, the special characteristics of the octopus have attracted our attention, and there are more and more mysteries about it, but countless evidences point to a result, that is, the octopus may not really be a "native fish" on the earth.

Octopus belongs to the class of molluscs, class Cephalopoda, family Octopus. It has 26 genera and 252 species, which shows that its population is still very rich and diverse. As a mollusk, the body structure of the octopus has repeatedly exceeded human understanding.

First of all, everyone can guess to what extent the octopus's "bone shrinking skill" can be used. The most familiar competitor in our daily life who has mastered the bone shrinking skill is the cat, so we often say that cats are made of liquid, but then the octopus tells humans through its own practice that it is the real "king of bone shrinking skill" .

In 2011, a fishing boat in Alaska, USA, caught an octopus. Its body was red and it belonged to the North Pacific giant octopus.

Video taken by the crew showed the octopus using its tentacles to search for gaps on the deck until one touched a small drainage hole.

The length of this drainage hole is about 10 cm and the width is less than 5 cm. People didn't believe that this giant creature could get out of this hole, but this octopus really stuffed itself into the drainage hole in full view of the public and finally escaped. Everyone who has watched the video said that the special body structure of the octopus is not like an earth creature at all, and no one knows where it learned the bone-shrinking technique.

In fact, this is not the first time an octopus has "escaped". Aquarium staff pointed out that octopuses are the most difficult creatures to manage. Because they know they are in captivity, they often look for opportunities to escape. And scientists have discovered after many experiments that although the octopus's tentacles and its head look large, as long as the hole is larger than its mouth, it can pass through. Because only the mouth is hard on the whole body of this mollusk.

In addition, octopuses also have "eyes" that are most similar to humans. Strictly speaking, the eyes of octopuses are better evolved than our human eyes. If you look up the relevant comparison pictures, you will find that our eyes are actually installed backwards. Therefore, human eyes have "blind spots", but octopus eyes do not have this shortcoming. Compared with them, our eyes are like pirated copies.

The octopus not only has a special body and original eyes, but also has multiple brains. Yes, we have always thought that living things can only have one brain. This does not apply to octopuses. As the top creature of the cephalopod class, octopuses have the same number of brains as the number of tentacles. In other words, an octopus with eight tentacles actually has eight brains. These eight brains will receive instructions from the head at the same time, and then start "busy in their own way."

Multitasking is easy for an octopus. For example, if you put it in a fish tank and put food on it, when faced with the new environment, it will stretch out a few tentacles to touch and explore the surrounding environment. The lower tentacles will grab food and bring it to the mouth. Moreover, the tentacles with independent brains will still move on their own even if they are cut off in critical moments. This is probably what we call "the hand has its own ideas".

It is worth mentioning that octopus arms can grow back after a period of time after being broken. This regeneration and self-healing ability makes them look even more different from earth creatures. In addition to the above special body structure, octopus also has super learning and imitation abilities.

The octopus's ability to learn and imitate is so extraordinary that many scientists call it the "primate of the ocean." According to research, when people put a jar containing crabs with a tightly screwed lid into an aquarium containing octopuses, they immediately began trying to open the jar with their tentacles. However, it still failed to open in the end, so the scientist took out a jar and demonstrated the "twisting" movement to the octopus. After carefully observing it, the octopus quickly opened the jar. It can be seen that octopuses have very strong learning ability.

In addition, it also has a strong ability to imitate. It seems to know what its strengths and weaknesses are. As a mollusk, it is the favorite delicacy of many fish in the ocean, so octopuses often look for "armor." For example, the hard shells of shellfish or coconut shells discarded by humans are its favorite equipment, so we can often see funny scenes of octopuses "walking forward with a shield" on the seabed.

It is not difficult to see from the above examples that finding armor is not an octopus’ innate ability, but its ability to imitate and learn based on acquired observations. Experts said that maybe the octopus discovered the special protective device of shellfish when eating shellfish, and then it learned to use it and used armor to protect itself.

The mimic octopus can confuse its opponents by changing its shape, color and movement. Humans have discovered based on observations that this octopus can imitate more than a dozen species, and the similarity is very high, so it is also known as the master of disguise in the animal kingdom.

Having said this, it is not difficult to see that the octopus does have many special abilities that make it completely different from the "native fish" of the earth.

Another research result shows that octopuses are not only different from fish, but their abilities in some aspects have even completely surpassed humans.

If what was mentioned above is just an "appetizer", then the following discovery can be regarded as shocking to mankind, and it has also become a new unsolved mystery about the octopus. In 2017, there was such an article in the journal "Cell" that caused an uproar. The authors stated that they had discovered that cephalopods have the characteristics of editing their own RNA.

The representative of cephalopod IQ is of course the octopus, and having the ability to edit RNA means that the octopus can transform itself at will, whether it is changing color or learning new skills.

In fact, humans can also edit RNA, but the number that can be edited is very limited. Taking humans as an example, only a few dozen of the 20,000 genes can be edited, but the editing points of the octopus account for 10% of the total. Even more than half of it. They use a special enzyme to remove the A base in the RNA and replace it with the I base.

Joshua Rosenthal, a neurobiologist at the Woods Hole Marine Biology Laboratory in the United States, said:

It can be seen that the ability of octopuses to modify and edit RNA by themselves is unique. Research not only shows its specificity, but also suggests it may actually be of extraterrestrial origin. After all, it is so different.

Since octopuses are so smart and have so many "superpowers", why haven't they become highly intelligent creatures? After exploration by biologists, it was discovered that there may be some kind of genetic lock in the body of the octopus.

It is true that the octopus's extraordinary learning and imitation abilities enable it to defeat most creatures in the ocean. To exaggerate, if octopuses can still do this on land, maybe they will evolve to be smarter than humans before long. After all, we only have one brain but it has eight.

However, the lifespan of octopus limits its evolution. Their lifespan generally ranges from 2 to 3 years. What’s even more amazing is that once an octopus chooses to reproduce, it is a sign that it is entering death. Why is it said that? Take male octopuses as an example. Most of them are much smaller than females, so it is actually difficult to mate.

In order to mate, male octopuses will cut off their sperm-containing arms, and the arms will move towards the female's coat cavity. Males who lose their handover wrists will die soon, so mating is actually the beginning of death, which is very similar to drones.

The process of egg laying and hatching by female octopuses is also very long, taking at least half a year. It won't go out to look for food during this time, which means it will become weaker and weaker. Therefore, when the baby octopuses are born, their mother is already dying and cannot teach them the acquired skills such as camouflage and attack. This means that although octopus is smart and can learn, it cannot pass on and continue this wisdom.

In fact, it is not just octopuses. There are also many scientists in the academic community who believe that all living things on the earth originated from extraterrestrials. Arrhenius, who won the Nobel Prize in Chemistry in 1903, proposed in his book "The Formation of the Universe" that the seeds of all life on earth originated from the universe. This theory is also called "cosmic panspermia".

This statement undoubtedly subverts our understanding of the origin of biology, but it does not rule out its real existence. As for the authenticity, its authenticity can only be verified as humans continue to deepen their exploration of extraterrestrials. .
