Those tropical ants are completely wrapped in amber and have outstanding beards, which have been perfectly preserved to this day.
It turned out that ants just passed by when the resin was dripping, so this sticky liquid stuck the ants, gradually wrapped them and sealed them alive. Now it has become an extremely important ancient biological specimen.
However, modern archaeology proves that the history of ants can be traced back to 200 million years ago. At that time, there were primitive ants in the plains and swamps of Central Asia. Later, with the changes of the earth's crust, climate and food, ants gradually evolved and began to live in groups on land, which can collectively feed the "queen ant" with strong fertility. Ants also exchange food, with a knot on their legs and hard armor. These characteristics of ants were formed about 654.38 billion years ago. Nearly 70 million years ago, it developed into more than 400 kinds of ants. The distribution of ants is closely related to the marine migration of the mainland. The base of ants is Eurasia. In the late Jurassic and early Baiji dolphin, many continents and continental bridges appeared. Through the Arabian Continental Bridge, ants spread to Africa, and through the Alaska Continental Bridge, ants reached America and the southern tip of South America.
Ants are one of the three largest social insects in the world. At present, there are 260 known ants on the earth, 15000 species. All soil layers have their footprints except the ice and snow in the North and South Poles. In tropical forests, there are about millions of ants living on every acre of land, and the number of ants is second to none among millions of terrestrial creatures, and its total amount far exceeds the sum of all kinds of terrestrial vertebrates.
The late British ecologist Professor Williams once estimated that there are about 654.38 billion species of insects living on the earth. If it is conservatively estimated that 654.38+0% of them are ants, then there are as many as 654.38+0 billion ants, with a total amount of more than 2 billion tons, accounting for 654.38+00% of the biomass of terrestrial animals, so ants are the largest on the earth. Ant is also an animal closely related to human production, and even necessary for human survival. Humans should attach importance to it, study it and popularize knowledge about it, so as to make better use of it and add gorgeous colors to human life in the future.
