There was a giant insect age on the ancient earth. The centipede can be several meters long, so how big is the mosquito?

The earth is a very rich life planet. In the long life evolution history of billions of years, countless kinds of creatures have been born. Most of the species have disappeared in a mass extinction, and only a few species can survive a mass extinction until now.

The size of creatures in different periods is also very different. Maybe many people know that 65 million years ago was the age of dinosaurs. At that time, dinosaurs were the overlord of the earth. They were very tall and they were real giants, standing at the top of the food chain.

Although dinosaurs in ancient times should be the tallest of the dominant creatures on earth, they are not the most frightening and frightening. What really makes people feel terrible and incredible is the age of giant insects 300 million years ago. That period was the Carboniferous period, the period when life began to explode in the history of life on the earth. At that time, it was not the big creatures that dominated the earth, but the very small insects in our eyes.

Maybe in the eyes of many people, insects are so small that they can be trampled to death with one foot. What’s so terrible? Yes, today’s insects are very small, but not in the Carboniferous period, when they were extremely large. Scientists have found specimens of ancient dragonflies, and found that their body length has reached more than one meter. The centipede in ancient times had a body several meters long and was the overlord of the insect world at that time.

Giant beasts roamed the earth in ancient times, and ancient insects were also extremely large. “Giant vein Dragonfly” was the air overlord at that time, and had the same superb flying skills as dragonflies now. They mainly feed on small animals. When hunting, they will dive to the ground like eagles and quickly catch the prey on the ground.

Some people may ask, is the insect the biggest in ancient times? Of course not. In fact, there were many creatures that were taller than insects at that time, but why were they dominated by insects? In fact, the reason is not complicated, because insects have innate fighting factors. As we all know, insects often have very hard shells, very powerful and sharp feet or other aggressive organs.

And insects are often Hercules. Take ants for example, they can lift food several times heavier than themselves, and their powerful strength, coupled with a strong body of defense and attack organs, enables insects to win with the weak. I believe many people know that even in modern times, insects with small bodies are not creatures at the bottom of the food chain. They can defeat creatures many times stronger than themselves with small bodies.

At the same time, insects are often social creatures. They move in groups. Naturally, other creatures can hardly be their rivals. I believe everyone has heard the story of ants killing elephants. Small ants are too small for elephants. However, because ants are powerful and social creatures, as long as there are enough ants, elephants will also be eaten by ants.

When it comes to insects, many people will think of mosquitoes that are very annoying to people. If you want to ask which kind of insects are most annoying to people, it must be mosquitoes. Every summer comes, mosquitoes will appear, they are often in our sleep, to bite, let us feel itchy, and mosquitoes can also spread disease, is a kind of let us hate and fear of biology.

Since ancient times, I don’t know how many people want to realize the desire to exterminate mosquitoes. However, with the development of science and technology, mosquitoes still can’t be exterminated. Even if all mosquitoes are eliminated this year, they will still reappear next year.

Since the mosquito is also a member of the insect family, how big was the mosquito when insects dominated in ancient times? Many people may think that the ancestors of mosquitoes should also be giant creatures like dragonflies and centipedes. But in fact, there were no mosquitoes in the insect world of the Carboniferous period, and mosquitoes did not appear at that time.

Mosquitoes did not catch up with the era of insect dominance. Research shows that the earliest ancestor of mosquitoes appeared in the Jurassic period 170 million years ago, which I believe many people will not be unfamiliar with. That is the age of dinosaurs. The ancestor of mosquitoes was born in the age of dinosaurs. Insects in this age have been less and less in the process of continuous evolution. They have long lost the charm of the Carboniferous era.

Many people may be very curious: Why did insects grow so big 300 million years ago? Through the research and exploration of scientists, we found that in the era of giant insects, the oxygen content in the atmosphere was very high, reaching more than 35%, far more than 21% now.

Because insects use the external respiratory system, they rely on the stomata on the body surface to exchange gas with the outside world, so in a high concentration of oxygen environment, their size can become large. Later, due to the emergence of mass extinction, the ecological environment has changed greatly, and the oxygen content is also decreasing. By the Jurassic, 170 million years ago, the oxygen content in the atmosphere had dropped to 26%.

According to the principle of survival of the fittest in nature, insects need to evolve to adapt to the new oxygen environment if they want to survive. So the insects are getting smaller and smaller. Even so, the insects at that time were larger than those at present. Take the newly born mosquito for example, its body size can reach about 8 cm, which is still very terrible.

If the size of mosquitoes can reach 8 cm now, it will definitely be a nightmare for human beings. You can imagine the scene of a group of 8 cm long mosquitoes swarming in, which makes people shudder.

With the occurrence of the fifth mass extinction, great ecological changes have taken place again, and the oxygen content in the atmosphere has continued to decrease to 21% of the present level. At this time, the size of the insect continues to shrink, becoming a very small existence. Seeing this, many people will have such a doubt: is the occurrence of the five mass extinctions not random?

It is believed that no one can give a definite answer to this. In the eyes of many people, it seems that the five mass extinctions occurred naturally on the earth, and there are no mysterious events behind them. Through scientific research, we have found that the oxygen content of the earth’s atmosphere has indeed decreased significantly after each mass extinction.

The continuous decrease of oxygen content in the atmosphere is also changing the biological structure of the earth, making the insects that used to dominate the earth withdraw from the stage. Let other organisms that are more suitable for evolutionary development, such as mammals, come to power. Insects naturally cannot compare with mammals in evolutionary potential. All this seems to be the result of natural evolution, but if we think about it carefully and analyze it, we will find that they are too coincidental.

As a result, many people once again thought of the “zoo theory” conjecture put forward by scientists. Some scientists speculated that the earth may be a laboratory set up by advanced civilization, and the creatures on the earth are the experimental objects. If this theory is correct, the evolution of life on earth may not be so simple. Of course, all this is just speculation,
