Which creature in nature is most similar to the human eye?

With the continuous development of national science and technology, human research on the natural world has become more and more profound. One of the animals that closely resembles humans was also discovered, and that was the octopus. Although the appearance characteristics of the octopus are different from those of humans, the octopus has its own conceptual thinking, and its eyes are very similar to human eyes.

And according to research, it has been found that the scope of what its eyes can see is much wider and more detailed than that of the human eye.

We all know that the octopus is an animal that lives in the sea, and it has eight octopus claws. It is also able to walk on its own with its claws, and its eyes, like human eyes, can see a variety of colors and objects。In addition, it can also see the small details of objects that are most easily ignored by human beings, and then transmit these scenes into the center of its own thinking.

And as this information is passed to its brain, his brain will make judgments about it.

Judge whether what he sees is good or bad for him. And then its body will make a corresponding defensive state. The octopus defense is done by changing the color of its body, because there are four pigments that can change color on the surface of the octopus, and it can change into four colors in total, yellow, brown, red and black.

With these color changes, it can be used to catch prey and dodge enemy attacks in this way, which requires a very high level of logical thinking.

can do it, and the octopus's brain has this function.

Although the octopus has the ability to think, its thinking is still relatively weak compared to humans, and it can only make some simple judgments. And in the whole natural world, we do not rule out the existence of species with the same high intelligence as humans. Therefore, we can only discover more of what we don't know by constantly exploring the universe as a whole.

In fact, for the natural world, orangutans and human eyes are actually the most similar, because humans are changed according to apes.

A dog's eyes are the most similar to humans, and many dogs' eyes are shaped like this. It looks more melancholy, so the dog's eyes are compared to those of people.

The eyes of monkeys are relatively similar to those of humans, both eyes are black, and the effect of seeing objects is the same, and there are many similarities between the two except for the eyes.

Insects have compound eyes, which are eyes peculiar to arthropods. It is composed of many small eyes, each of which can only feel a small part of the image, and the image that all the small eyes see can be brought together to form an overall impression. Therefore, the insect with the most "eyes" refers to the insect with many small eyes.

The compound eyes of dragonflies are the largest and most in the insect world, accounting for 2 3 of the entire head, and the two large compound eyes of dragonflies have been scientifically detected to be composed of 1000 28000 small eyes, so dragonfly eyes can reach up to 10,000, which is 10 times that of ordinary insects!

As the animal with the most eyes in the world, dragonflies not only have many eyes, but each eye has its own system, each with its own refractive system and sensory cells, so it has vision. This also leads to the dragonfly's astonishing vision in both eyes: the upper part looks far away, and the lower part looks close.

This kind of vision also allows dragonflies to catch small insects in the air, and they never miss.

Dragonflies not only have many eyes, but they can also move freely with their necks (most of the eyes of insects cannot move), so dragonflies can look around and look around, but humans can also use this property to catch dragonflies.

In fact, in addition to dragonflies, the animals with the most eyes in the world are also among insects, such as bees, fireflies, beetles, mosquitoes, moths, houseflies, etc., they all have many eyes, among which the compound eyes of houseflies are significant, consisting of about 4,000 small eyes.

Not only that, but some insects also have more than two large compound eyes. The praying mantis, for example, has three small single eyes in addition to its two large compound eyes. These monocular eyes are only photosensitive and cannot see, but biologically, they are still eyes.

Spiders have eight eyes (except for special cases, of course), and these eight eyes are actually monocular, that is, the same as the small eyes of the praying mantis, although there are many, but more can only see light and dark, and have no real vision. So eight eyes can also help it better judge its prey. In addition to this, spiders perceive their surroundings through the hair on their legs, and it can be seen that vision is not an ability that it mainly relies on.

A long time ago, bilaterally symmetrical animals began to grow one or more pairs of light-sensitive eyespots, with no vision but only sensory abilities. Some of its descendants will carry forward a pair of eyes and enhance the visual ability of the eyes; Some choose to have more than one eye to compensate for the lack of a single eye.

Insects.

Spider, eight eyes. Dragonflies, lots and lots of eyes.

There are insects, and there are more eyes.

If each refractive crystal of the compound eye is counted, the dragonfly is probably the animal with the most eyes, at least tens of thousands of eyes.

If the entire closely packed compound eye were taken as a whole eye, then the scallops in the sea are probably the most eyed animals, with at least hundreds of eyes.

Insects, most of them are compound eyes.

Creatures with a particularly large number of eyes include spiders, which have 8 eyes, and dragonflies, each of which has about 10,000 small eyes.

Many insects, such as dragonflies and flies, you think they only have a pair of big black or green or yellow eyes, but in fact they contain thousands of compound eyes, too many to count.

Among insects, there are many species with many eyes, among which houseflies have about 4,000 small eyes, dragon lice have 9,000 small eyes, butterflies have 12,000 to 17,000 small eyes, and dragonflies have the most eyes.

A scallop has more than 200 eyes!

Being stared at ...... by so many eyesI really have to put some vermicelli to cover it, otherwise, it will be a scary ...... to eat

1. It is not color blindness, and the vision is similar to that of a person, which is very large and thin, and asks the unique vision of each movement in this case. It should be largely absentHowever, there are also differences in vision between different types of animals and between different individuals of the same class.

2. Man evolved from gibbons, so his eyesight is similar to that of gibbons.

3. Among the extant sailing animals, the animal with the best eyesight is the mountain eagle.

4. The gliding force of human vision is not as perfect as you imagined!

Animals with bilaterally symmetrical and cephalic features usually have a pair of eyes, which are not the same for mollusks and arthropods such as insects, and many animals that have lived in the dark all their lives have evolved to lose their eyes altogether, such as burrowing fish. The evolution of the eye is of great significance because light contains a lot of information about the environment around an organism, so the ability to perceive light can greatly enhance the adaptability of living beings. The reason why animals usually have two eyes is because of two laws of evolution, homology and convergent evolution.

Chordates including fish, birds, amphibians, and mammals are all eyes because they have evolved to retain a common ancestor's trait, i.e., homology. However, the eyes are adapted for different purposes in different chordates, for example, some animals specialize in seeing at night, some animals can see different colors or some can only see black and white.

For living organisms, the eye with its complex structure requires a lot of energy, not only physiologically the eye needs a lot of energy to grow and maintain, but a large part of the brain must be used to interpret the signals input from the eye, so animals did not evolve a third eye. In general, animals that are often subjected to predation have eyes that grow on their sides like rabbits, and can sense the arrival of predators more quickly by maximizing their field of view; The eyes of the carnivore are placed side by side in front of the face, and by overlapping the visual fields of the two eyes, depth perception is obtained.

The eyes of invertebrates are not related to the eyes of vertebrates in evolution, in fact, the two did not even evolve from the same cell structure. Convergent evolution occurs when different organisms evolve similar traits based on similar selection pressures. Having two eyes allows you to compare light from two different directions, and even if the field of view does not overlap, the left and right contrast can determine the orientation, so only two eyes are needed for positioning.

Cephalopods, including octopuses and squids, are similar to vertebrates in that they evolved two eyes independently, and the two independent evolutions of the eyes in living organisms are one of the best examples of convergent evolution.

Because this pair of eyes is completely sufficient, it has adapted to the environment and meets the needs of growth.

Because it's the result of natural evolution, and it's already convenient to do things with one pair of eyes.

Because this is the best choice for living things to evolve for such a long time, it is in line with natural selection.

Because we have evolved to have one pair of eyes, and we have not had too many pairs of eyes.

Because there is a symmetry, a pair of eyes can see more clearly.

That's the nature of living things, and if every creature has two pairs, three pairs of eyes, isn't it a monster?

It's evolved over a long period of time, and it's still very beautiful.
