Next, let's take a look at where the octopus is special. First, the blood of the octopus and the vast majority of species are different, its blood is blue, after the scientists found in-depth research, only to know that the original octopus to be a lot more powerful than humans, first of all, the octopus has three hearts, of which two are specialized in gills for blood supply, the other is to the whole body for blood supply, if you think that it is only the heart is not the same, it is a big mistake.
Second, the brain of the octopus is its most awesome place, it has 9 brains and up to 500 million neurons, octopus 9 brains are 1 main brain, which is located in the nerve center, the rest of the 8 secondary brain is located in 8 carpal feet. The main brain alone accounted for 40% of the neurons, the octopus of each secondary brain have the ability to act autonomously, can make a rapid response to the external environment, many of their behavior do not need the instructions of the main brain, which makes the octopus has a very strong ability to learn, and has a conceptual thinking, that is, they are able to independently deal with some of the more complex things. Scientists have octopus in a bottle cap screwed in a glass bottle, did not think that the octopus can open the bottle cap to escape, this experiment seems simple, but never seen the bottle cap of the octopus actually know the way to use the rotating can open the bottle cap, this may not have seen the bottle cap of the ancient human beings are not sure to do.
Third, the eyes of the octopus is like a camera as high-definition, because it is a mollusk, it is flexible body can be twisted into any shape, the most cattle is the octopus can easily change their color and form, in the critical moment can be mimicked into a sea snake, jellyfish or lionfish and other creatures, but also very good, this skill can not only be used to capture food can also be used to avoid the attack of the natural enemy, it can be said to be a double whammy. This skill can be used not only to catch food but also to avoid attacks from predators.
But these can only show that the octopus is a very strange creatures, and can not effectively prove that the octopus is not an Earth creature, the reason why scientists speculate that the octopus is not an Earth creature is because the octopus in the evolutionary process of a special mechanism, the octopus can edit their own RNA, these RNA can be rearranged in the genome, control of their own genetic material, but look at the known on the planet, only the octopus can do However, looking at the known creatures on earth, only the octopus can do this one thing. Scientists speculate that the octopus may not really be the earth's native fish, and this speculation raises a new question, how life on earth is the origin of the answer we currently have is the theory of biological evolution put forward by Darwin, but the theory of evolution only tells us the process of biological evolution, and did not say that the creature is how to appear, in addition to 540 million years ago the Cambrian explosion of life, the phenomenon violates the principle of evolution, and the theory of evolution is not a good idea. Phenomenon violates the principle of evolution, but Darwin did not give a reasonable explanation, so some experts speculate that life is not originated on Earth, but from the seeds of life in outer space, these seeds are ubiquitous in the universe, and through the comet in a frozen dormant state was brought to the Earth, and then melted awakening, began to evolve on Earth, which explains the origins of life as well as the Cambrian explosion of life. The octopus's strange features are the strongest support for this theory.
