There is such a creature on Earth that seems to be smarter than us humans.
, and its physiological structure is very special. Today we will learn about this animal that was once considered an alien creature. It's an octopus.
Octopus has three hearts.
Two hearts are used to supply blood to the cheeks, while the other heart is responsible for supplying blood to the whole body.
and octopus also has two memory systems. One of the memory systems is the octopus' brain, which accounts for about 40% of the total number of nerve cells.
, and another memory system accounts for about 60% of the total number of octopus nerve cells.
and these nerve cells are directly connected to the suction cup of the octopus.
We all reflect on human physiological structure. Humans only have one memory system, which is our brain.
Our brain is equivalent to the general command system of the whole body. All organs in the body must be unified in command and dispatched by the brain.
If the limbs want to complete a complex movement, the brain must make instructions before it can be completed.
However, octopus does not need such complicated connections.
octopus's brachial legs also have their own independent memory system.
They can independently complete some extremely complex actions without being under the command of the brain nervous system.
Therefore, biologists discovered a bizarre phenomenon when observing octopus. Octopus sometimes acts that cannot control itself.
Octopus' blood is blue.
This is also the most unique feature inside its body from other animals.
Perhaps it is precisely because of its blue blood that it can survive in many complex environments.
octopus' brain structure is something modern humans cannot imagine. When biologists observe octopus brain cells and neural elements, they found that there are at least 500 million neuronal systems in the octopus.
What makes people feel even more incredible is that octopus also has similar learning and memory abilities to us humans.
In the previous topic, we have introduced to you the bizarre phenomena that occurred in a Japanese aquarium.
Scientists use octopus to conduct experiments to verify the wisdom of octopus.
They put an octopus in a jar where the caps can be tightened.
After a while, the octopus made an incomprehensible action.
It can actually rely on its own suction cup to successfully unscrew the bottle cap. This is something that no second animal can do in nature except humans.
So octopus was once suspected by scientists to be an alien creature.
This is why when people watch many science fiction movies, directors will regard giant octopus as an alien creature.
So when we say this, we may feel creepy.
So far, octopus is the only creature in nature that has the potential to surpass humans. is even smarter than us humans from a cognitive perspective.
In contrast, we humans, from the Homo sapiens era to the modern society, have only experienced millions of years.
And we speculate that in millions of years, it is possible that octopus will evolve the same level of wisdom as our humans.
Nature is infinitely mysterious, and the speed of evolution is not predictable by modern humans, so everything is possible.
