Life on earth is very tenacious, just like a leek that will continue to grow after cutting off a crop of leeks, which seems to be endless. In the 3.8 billion years of development and evolutionary history, life on Earth has undergone more than 20 species extinction events of various sizes, especially the five mass extinctions of species with a large scale and impact, which will cause more than 80% of the species on Earth to disappear at that time. However, millions of species still exist on Earth to this day, and all those who can continue to this day are the best.
There is a very unique temperament among the many species on earth. They have three hearts and nine brains, can deform, disguise, can use tools and can "walk upright". It is an octopus that we are both familiar with and unfamiliar with. What we are familiar with is that they are more delicious as food, and what we are unfamiliar with is that the various characteristics of octopus are not like creatures on earth at all.
Some people say that they come from life outside the earth, otherwise why do they have so many strange attributes?
The octopus is actually "flirting"?
Recently, scientists have taken a video of octopus throwing things. Of course, the throwing things here is not about using 8 wrists, which is a bit too anthropomorphic. Instead, it is through a tubular organ in the anatomical structure of the octopus. The octopus can spray water outward at high speed through this tubular structure, similar to a hydraulic bomb.
From A scientific research team at the University of Sydney published their research results in the journal Plos One. The video of octopus "throwing things" was taken from 2015 to 2016. Scientists put cameras in the underwater world for 24 hours on the Australian coast, recording details of 102 dark octopus (Octopus tetricus) when they were active under the sea.
I saw some octopuses collect fragments in the mud of the sea or eat the shells left when eating food. All of the collected debris are stored in a certain position on their bodies, and then they are quickly ejected, most of which are in other octopuses nearby.
octopus "throw things" behavior is very similar to the mutual fighting between humans, but scientists found that two-thirds of the throwing behavior occurs on female octopus, and the targets are mostly male octopus that are deliberately approaching. Scientists believe that this "throwing behavior" of octopus is related to mating interaction. To put it bluntly, two octopus are "flirting".
The strange thing about octopus is far more than this
Octopus is indeed a very smart animal, but if compared with mammals, it can be said that it is in the sky and in the ground. The millions of species on the earth are the only species of humans. Smart does not mean that they come from alien planets. From the perspective of the biological evolution theory of Darwin , this is just a "foundation of one's own life", just like some wild animals have sharp teeth and claws. What's strange about
The octopus is that as mollusk , it is too smart and acts out of place!
01. Octopus has too many "mind"
The elderly at home describe their children as smart and clever. Sometimes they say that the child has a lot of "mind" , and octopus is exactly in line with this characteristic. People have three "mind" . The larger one provides blood circulation to in the whole body of the octopus, and the other two smaller hearts specifically supply blood to the gills. Of course, this has nothing to do with whether the octopus is smart, as long as it is beneficial to their activities.
02, and nine brains each fight
Octopus is a general term for 252 animals in the 26 genera of the Octopus family. It belongs to molluscs because there are eight brachiopods, which are also called octopus. Most people’s familiarity with octopus is just their deliciousness, but this guy is really special.
Octopus has 9 brains, which is not a characteristic that ordinary animals can possess. There is a brain on the head of the octopus that controls the central nervous system , which occupies 40% of nerve cells. This is a separate memory system. In addition, each brachiopodia of the octopus also has a "brain", or has some brain functions, accounting for 60% of the nerve cells in total.
In other words, the eight wrist-foots of the octopus can each do their own business, and the brain sits at home and has control. It is precisely because of this that sometimes, after the octopus dies, its brachiopodia can continue to "survive", which is a strange species.
03. "Modify" the gene until you are satisfied with
. Students who have a little understanding of biology know that the core of expression of various traits of biological lies in genes, and the expression process of genes requires to transcribe to form RNA, and RNA then synthesize the proteins needed by the body through translation. This is the "central law" that most organisms on earth will strictly abide by.
But octopuses are quite special. They can temporarily adjust the RNA transcribed through DNA. If the RNA changes, it means that different proteins will be synthesized, which means that octopuses can change their traits by not changing their genetic form. This method is very clever.
said that in the end
The uniqueness of octopus' own attributes also gives them many "unique skills". Everyone knows that octopus is smart, but where is it manifested? I believe many people have watched the video of octopus "opening the bottle cap". If they seal them in the bottle, the octopus can open the bottle cap inside by itself.
Octopus is truly unique in their daily life. First of all, it is its ability to disguise. Octopus can change color well and integrate its surroundings into one. If you don’t look carefully, you can’t find it. Secondly, they will also find protective covers for themselves. Some octopuses often hide in coconut shells and run quickly when moving.
Octopus is out of place, and it makes people suspect that they are really alien creatures!
After all, scientists have discovered organic matter raw materials for life in some meteorites, such as ribose , amino acid , protein, etc. So it is possible that the meteorites hit the earth and brought some seeds of life, right?
