Why don t people have three eyes?

When humans evolved, cells were combined into two eyes, so humans only had two eyes. Evolved to not have enough cell tissue to form three eyes.

Brother, this question is really amazing, why not long? There's a genetic problem, an evolutionary problem, and if you can live for 3,000 years, maybe you'll have three eyes.

Because man has only two eyes

The three eyes cannot have a shadow on the same line.

You think you're the god of Erlang.

Yes, and corns, haha.

Science has proved that human beings used to have 3 eyes, but because they are not used often, they are gradually degrading, and they can be searched on the Internet, which is not a boring question.

Jiro God doesn't like reincarnation.

Yes. The book says that it has been medically studied that the front part of the pineal gland of man has an eye, or that it has all the structures of the human eye, and it is admitted medically that it is a vestigial eye.

In ancient China, there was a similar saying about opening the heavenly eye, and the current special function of the heavenly eye is similar to the third eye.

The pineal gland is an oval-shaped body with a reddish color. It is located in the upper posterior part of the human thalamus. It is attached to the posterior aspect of the roof of the third ventricle.

The pineal gland is the third eye of the human body. It seems inconceivable to say that the human body has a third eye. In fact, biologists have long discovered that there is a hole in the skull of ancient animals that have long been extinct.

Biologists were puzzled at first, but it was later confirmed that it was the frame of the third eye. Studies have shown that birds, animals, frogs, fish, turtles, snakes, and even human ancestors have had a third eye. It's just that with the evolution of living things, this third eye gradually moved from the outside of the skull to the brain, becoming the "hidden" third eye.

Although the pineal gland moved into the cranial cavity of the black hole. "Living in a simple place" and "isolating from the world" cannot directly observe the colorful world. However, because it once performed the function of the third eye of the human being, it can still feel and respond to the signals of light with its original "unique ability".

For example, people feel in a better mood, more energetic, and less sleepy on sunny days. On the other hand, when encountering drizzling and hazy weather, they will be depressed, depressed, and often think about sleep. This phenomenon is precisely the pineal gland in "worship".

We often forget about our third eye because this extra eye has left its original position and is buried deep in the brain, in the upper part of the thalamus, and has another name called "pineal gland".

Yes. It's right in the upper thalamus of the brain! It is called the pineal gland.

Studies have shown that fish, amphibians, reptiles, birds, mammals, and even humans all have three eyes. People often forget about their third eye, or never think it exists, simply because the extra eye has left its original position, not on the surface of the face, but is buried deep in the suprathalamus part of the brain. The third eye has become a very distinctive, specialized gland, and no other gland in the human body has astrocytes (which are abundant in the cerebral hemispheres) except for the pineal gland.

Now, the function of the third eye is very different from that of the other two eyes, but it is still a bit "disconnected", and the pineal gland is extremely sensitive to sunlight, which is connected to the eye through nerve fibers. The pineal gland is inhibited by sunlight when the sunlight is very strong, and secretes less pineal hormone; On the contrary, in rainy weather, the pineal gland will secrete more pineal hormone. Excessive production of pineal hormone reduces other hormones that arouse cell work, making people feel listless and lethargic, which is why people feel sleepy at night or in the winter when there is less sunlight.

Hey, it's a pity that our third eye can't give us supernatural powers, I wish I could use my third eye to see ghosts, or see through objects (like Superman) and see the future! Wow, how cool that would be!
