In the history of the earth, it should be the most familiar to us, prehistoric creatures, they are huge and diverse.
But you know what? More than 300 million years ago, there were also giant organisms on the earth, and the land at that time was not as scattered as it is today, but was in a process of gradual aggregation.
The climate is warm and humid, full of lush tall trees, and some of the coal we use today was formed during this period, so it was named Carboniferous, and the Carboniferous Period was the peak of the oxygen content of the earth's atmosphere, and the oxygen concentration was almost twice as high as it is now.
If you want to ask the most life in the world today, it is estimated that many people subconsciously have to say that of course it is human, after all, there are more than 7 billion, but if you think about it carefully, it should be insects, although we are used to calling the current era the age of mammals, but in terms of the number of insects can be much more than us, human beings have 7 billion, but the number of insects is 100 billion, some people must think, so what, we are much bigger than them, and the rules are set by us, but as the saying goes, who has not yet had a past, In the past, well... A little further afield, about 315 million years ago, the world was actually ruled by these bugs, and they were not only huge in number, but also in size that would make your jaw drop.
Affected by this, many arthropods appeared during this period, and they were also extremely large, and the dragonflies that we usually could catch with one hand became as big as eagles, and the scorpions of the Carboniferous period if they were put to the present, except for us, it may be difficult to meet natural enemies, not only have a hard shell, powerful pincers but also have poisonous tail spines<>
Malu, body length can reach up to three meters! They're fast-moving, and they're covered in armor, making them creeping overlords!
Although the excessive oxygen content and the flourishing trees also mean that fires occur frequently, this does not affect their reproduction too much, and the earth has officially ushered in the age of giant insects!
Until the end of the Carbon Age, the earth began to enter a short, ice age, the sea level dropped sharply, the climate changed, and the continuous jungle that covered the sky and the sun collapsed into a discrete "oasis", large areas of land began to desertify, and the oxygen concentration was greatly reduced, which was the "rainforest collapse event" of the Carboniferous Period, <
After the event, arthropods began to develop towards miniaturization, and the glory of the past will also be replaced by other organisms, natural selection, survival of the fittest, will always be the law of nature.

300 million years ago, the age of giant insects was due to the extremely high oxygen content in the atmosphere, so many arthropods grew very large, and the trees at that time were also very tall, and the animals were very large.
-
At that time, arthropods were very large, a mosquito was bigger than your palm, and a dragonfly was the size of a human.
-
300 million years ago, the age of giant insects was probably the time when a single ant could trample a person to death, and a centipede could harm an entire forest, and they would probably kill each other.

Hello, the mayfly is exactly the same as its ancestor 300 million years ago. Mayflies are the oldest living winged insects, dating back to the Carboniferous period about 300 million years ago. They have evolved to adapt to life in the water during the nymph stage and to the fast and efficient way of reproduction.
Like many other insects, mayflies go through different stages of metamorphosis during their lives. The first two occur in the water, first the eggs and then the larvae. After hatching, mayfly larvae feed on their feeding fingers, grow and develop, some males build nests to live and feed, while others only wander through aquatic vegetation in search of food.
Mayflies are unique in that they have winged relatives in two of their four life stages – egg, larva, sub-adult, and adult. Hope it helps you <>
Do you have any other questions that I would like to answer for you, dear? <>

300 million years ago, most of the land was in the tropics, and plants flourished (after burying into the ground to form coal, hence the name of the period.
Carboniferous. )。But after about 50 million years, from.
Permian. In the middle to late period, these giant species died out.
Scientists have long speculated that perhaps changes in atmospheric oxygen levels played a key role in their rise and fall. Now, paleontologists.
Start with the rise and fall of these ancient dragonflies, cockroaches, and other super-sized insects that are about the size of today's eagles.
Oxygen content. Relate.
Nitrox. The concentration created the ancient giant insects.
Carboniferous. Earth's atmosphere.
The oxygen concentration is up to 35%.
Not so long ago, Yale University in the United States.
One published by biologist Robert Bernard et al.
Paleoclimate. Research confirms this hypothesis.
The researchers noted in the report that the Carboniferous.
At that time, the concentration of oxygen in the Earth's atmosphere was as high as 35%, which was much higher than the current 21%. Many arthropods absorb oxygen directly through the tiny tracheas that dot their bodies, rather than indirectly through the blood, so high oxygen levels can encourage insects to evolve in the direction of larger size.

Everyone knows that there have been living things on the earth for a very long time, and there really were giant insects on the earth in ancient times, because there are fossils to prove it. In ancient times, every living thing on the earth was huge, but with the change of the environment, many became extinct, dinosaurs are a good example, chemists have found dinosaur fossils and fossils of other creatures, fossils of creatures in ancient times, proving that in ancient times the earth was the existence of giant insects. <>
One. The Earth's environment is home to a lot of life.
In this era, human beings are the most advanced animals on the earth, creating many things that nature does not have, nature is very magical, and by making good use of nature's resources, you can create a beautiful world. In ancient times, it was also the age of dinosaurs, and dinosaurs were everywhere at that time, and insects were also giant insects, and many creatures had legs. With the change of the environment, we all know that the law of survival is the survival of the fittest, the unfit are eliminated, and if you do not adapt to the changes in the environment, you will be eliminated by the environment, leaving the creatures on the earth now.
Two. The fittest survive, and the unfit are eliminated.
Everyone knows that human beings also evolved, in ancient times, when there were no human beings, human beings evolved from apes, from the beginning of crawling to the current straight walking, learning to use tools and creative tools, using both hands to create their own world. I have to marvel at the greatness of human beings, but because human beings have caused harm to nature now, and the environment has changed a lot, we must love the environment and live in harmony with nature, because man and nature should live in harmony. Once upon a time, all kinds of living things in the world were huge, and now the best proof of this is fossils, which can infer what that creature looked like at that time, the environment is changing, living things are evolving, and maybe many years from now, human beings will change a little.
Do you think there were giant insects in ancient times, and have you ever seen the fossils of previous creatures?
Hehe! The life span of the earth has been analyzed by the scientific community authoritatively, and the result is that it is only 100 million years, so 100 million should not exist, but there are other factors affecting him, the external factor is the sun first, because it is the closest to the earth, and the planet that can fate on the right earth That is to say, all the energy and power on the earth come from the sun, and once the sun has three long and two short, it will inevitably affect the earth. Before the 30s of this century, people always thought that the sun would one day burn out, turn from white to orange and then to red, and finally become a dark star that was silent, but its brilliant life. >>>More

Perhaps for most people, fossils are nothing more than the corpses left behind by animals after death, but for many archaeologists, the research value of fossils has always been very high. Moreover, the understanding and research of fossils by archaeologists in China is definitely not limited to China, but also to the world. Knowing that the same type of fossil may be found in multiple countries around the world proves that the species has a certain degree of migratory ability. >>>More
What do today's school uniforms, 100-year-old school uniforms, and 1000-year-old school uniforms look like?
I don't know how, the situation should be different in every place. In life, most of the things used are aluminum pots, coal is used to boil water, electric lights are yellow, when they get married, girls want to have a sewing machine, the house is brick and tile, there are markets that will fix the time, such as every Wednesday and every seven days every month, everyone goes out to catch the market, there are supply and marketing cooperatives are citizens down to open shops, at that time mobile phones were not popular, the Internet has not heard of it, motorcycles are also successively until 00 years later, every family has it, basically everything is done by hands. In terms of burning incense and worshipping, it is very important, and on fixed days, such as the Bodhisattva's birthday, basically everyone will take a picture in the house, and the famous temple fair gathers people from the surrounding villages. >>>More
