Rare photo: Snake eel emerges from the belly of the vulture, but it flies calmly, what's the situation?
"Natural selection for the survival of the fittest", whether it is human society or nature, competition is cruel. All species in nature and within species have to compete with each other, and only the most powerful can win and finally be selected to stay. After the defeat in the Sino-Japanese War in the late Qing Dynasty, the Chinese nation finally realized that standing in the forest of the world had reached the most critical juncture. A group of people of insight also began to open their eyes to see the world, and were the first to spread new ideas. Huxley's "Evolution and Ethics" had a huge impact on society after being translated by translator Yan Fu. The concept of "natural selection, survival of the fittest" greatly shocked people's hearts and greatly promoted the enlightenment of thinking at that time. Even the familiar Hu Shi was named because he was deeply shocked after reading this book, so he took the word "Shi" as his name.

Inventory of the top 10 birds that easily kill humans in seconds
For most people, birds usually rank very low on the list of the most feared animals, and rightfully so, after all, most birds are too small and lack natural weapons to cause serious harm to humans. They come in many varieties, sizes, and colors, and for their part, they've been used in practically everything - from business logo designs to government and political party emblems, to high culture and accessories, and many other things. But size and strength aren't the only weapons birds use to kill, dagger-sharp beaks, incredibly powerful claws, and even poison are in their arsenal, not to mention the sheer amount of power. Anyone who has been dive-bombed by a mad crow or a seagull will know this, just as everyone knows the traditional movie The Birds.

my country's manned moon landing may be ahead of schedule. Experts mention the lunar rendezvous and docking plan for the moon landing, which can be realized on the fifth day of the year.
At the China Aerospace Conference on April 25 this year, Mu Yu, director of the General Design Department of the First Academy of my country Aerospace Science and Technology Group, first introduced the Long March 9 that my country is developing, saying that it has a diameter of 10 meters and a lunar orbit carrying capacity of not less than 50 meters. It will provide important support for the establishment of lunar bases and the completion of larger-scale lunar exploration projects in my country's lunar exploration and lunar landing activities. But when he introduced these, he also said another manned lunar landing method, that is, at the current stage, if our country uses the method of circumlunar rendezvous and docking, and disperses the pressure of rocket launch through a comprehensive plan, then the low-Earth orbit carrying With a capacity of 27 tons, the goal of manned moon landing can be achieved, and the rockets it uses do not need giant rockets like the Long March 9.

The earth once had a rain of more than 10 million years. Will such weather still appear in the future?
If one day you can take a time machine to the earth 4 billion years ago, then for you, this is definitely a purgatory-level existence.
