Octopus is a strange and clever creature. They look like aliens. They have tentacles and the ability to disguise and transform. At present, many sci-fi novels or movies about aliens have created their own octopus aliens with many tentacles. In fact, few people in the scientific community agree that octopus comes from outer space. The argument that octopus may be an alien put forward in 20 18 paper is only a further discussion of the theory of "origin" The theory of "source of students" comes from the ancient ideas of ancient Greece.

1. The gene composition of octopus is very complicated, with more than 30,000 genomes, more than that of humans 1 10,000. Besides, octopus has nine brains and more than 500 million neurons, while the number of neurons in mice is only 800 million, so the IQ of octopus is second only to that of primates. Among the nine brains, the main brain in the head accounts for 40% of neurons, and the other eight brains have only one or eight wrist feet. Each tentacle can respond quickly to external stimuli without the control of the main brain.

2. Traditionally, octopus evolved from Nautilus about 500 million years ago. But this relationship cannot explain how octopus, a strange cephalopod, got all these characteristics, or why octopus is so genetically different from their close relatives. Octopus and their close relatives are very different in heredity. Its big head, complex nervous system, camera-like eyes, sensitive body, and the ability to instantly disguise by changing the color and shape of the body are all amazing features that suddenly appeared in the process of evolution. Therefore, researchers believe that octopus genes seem to be obtained from other distant planets in the universe. In other words, foreign genes changed the primitive ancestors of Bird.

Anyway, octopus is actually a discussion about the origin of life on earth. Whether there are alien bacteria and viruses in the evolution of life on earth is unknown at present. As long as the true nature of life is solved, maybe I can know how life on earth came from.
