Octopus has 9 brains, 3 hearts, has a strong gene editing ability, the number of genes in the body is 40% more than humans, why did not evolve the "octopus civilization"?
The octopus, commonly known as the octopus, has eight tentacles as the name suggests, and is the most intelligent of mollusks and invertebrates.
In addition to being cooked and eaten by humans, octopus can also be used as a medicinal herb with the effect of tonifying blood and qi. Octopuses are carnivores that feed on small fish, crabs, shells, etc., and large octopuses also prey on larger fish than themselves.
Octopus has a total of 9 brains, one of which is a master brain and 8 sub-brains, the main brain grows in the head, very similar to the human brain, 8 secondary brains grow on 8 tentacles, these 8 parabrains are to help the octopus to remember, each tentacle brain will transmit the information of its own memory to the main brain, the main brain and then carry out related sensory behavior analysis. The octopus has a total of 3 hearts, 1 main heart, 2 paracardia, the role of the main heart is to supply blood to the whole body, the role of the paracardia is to assist in the blood supply and filter out the waste products in it, somewhat similar to the kidneys in the human body.
The octopus does not have many natural enemies in the ocean, the strength is very large, each of its tentacles has more than 300 suction cups, each suction cup pulls up to 100 grams, and once the small and medium-sized creatures are sucked, it is extremely difficult to escape. There are many pigment cells in the octopus, which can change color according to the color of the surrounding environment, just like chameleons.
The octopus has a very strong learning ability and imitation ability, the scientist put the lobster into the jar, in front of the octopus repeated the process of unscrewing the jar twice to take out the lobster, and then put the jar in front of the octopus, the octopus actually imitated this action to open the jar.
The role of genes is to carry memory, and the number of genes in the octopus is quite large, up to 33,000 groups of genes, and humans only have 20,000-25,000 sets of genes, so many gene numbers are edited by the octopus itself. When the genetic information on the genome is copied and transmitted, the DNA will be transcribed into mRNA first, and then the mRNA will be translated into proteins, and humans can only modify a very small number of mRNA, while octopuses can edit most of the mRNA, which is why octopuses have super intelligence.
For octopuses with such a high IQ, why didn't they evolve their own octopus civilization?
The first is that the lifespan of the octopus limits its evolution, the general octopus lifespan is about 3 years, compared to the average lifespan of 71 years old humans, the octopus is undoubtedly short-lived, such a short life makes them have no time to do more things.
The second is the unique life habits of octopus, compared with humans who love social life, octopus is a complete "loner", it is more willing to go alone, unwilling to communicate too much with the same kind, high intelligence individuals can not be integrated through the same kind of gathering communication.
The third is that the octopus is still an invertebrate after all, no matter how developed its computers and genes are, invertebrates are inherently more restricted in size and intelligence than vertebrates.
The fourth is that octopuses live in water, and the oxygen content in the water is much lower than the atmosphere on land, which cannot support the octopus to evolve more brain neurons, and the number of brain neurons in octopuses is only 5-6% of that of humans, and they cannot think deeper like humans.
As the saying goes, when God closes one door for you, he opens another window. For the octopus, God gave it a super high wisdom, but at every turn gave it limits.
