Then there will not be so many high-rise buildings, cars, and airplanes in the world, and human beings will still be called human beings! The Earth will not be called the Earth, and the mammals will dominate the world!
Humans have been living on Earth for hundreds of thousands of years now, and we know from the theory of evolution that humans first evolved from a single-celled organism living in the ocean. Humans evolve differently depending on the environment in which they live, whether due to direct sunlight or land or water.
What we learn from the biology course is that human beings first evolved into apes and slowly became what they are now, and now the world is most similar to monkeys and orangutans in terms of appearance and division of hands and feet, but humans have learned the division of hands and feet and used tools, and slowly formed a group, and then let the brain evolve step by step into the current human. Human beings are also animals, but now we claim to be advanced animals, and in terms of feelings, general animals also have them, but we are more intelligent, that is, our brains make us more advanced, so we have created the current human civilization.
So where will humanity develop in the future? Some scientists have speculated that human beings will inevitably develop in the direction of artificial intelligence in the future, that is, robots, but as far as the current situation is concerned, robots are far from being able to have their own feelings and thoughts, and humans are using computers and chips to control and <>
If you combine humans and robots, it's really a little too scary, just like those science fiction movies we watch, in the end, the biggest war on earth is not between countries, but between humans and machine intelligence. Robots are created by humans for better and faster development of human civilization, but if humans give robots feelings and thoughts, and robots are not used by humans, then the results are undoubtedly terrible.

will develop into being able to live both on and off the water.

If humans were amphibians, there wouldn't be so many buildings, and air pollution might not be as bad.
-
Then we don't have to live in a building.
-
In the summer, the sea was full of people diving.
-
There shouldn't be so many high-rise buildings.
-
You can live on the road or in the water, and the ocean area is large and there will be no traffic jams.
-
There may not be so many buildings.
-
The housing problem has been alleviated to a certain extent, the use of air conditioning has been reduced, because you can enter the water to escape the heat, and your understanding of the ocean will be more profound.

Then the use of air conditioning will be reduced because you can enter the water to escape the heat, and your understanding of the ocean will be more profound.

It is the host of a variety of parasites, viruses and bacteria, and cooking cannot completely eliminate them. Among them, there are two kinds of nematodes that are more harmful to human health, Acanthopalatine nematode, Diegong mansoni and Bissophobi. When people eat meat with these worms, the worms may molt in the human body and transform into third-stage larvae or early adults, causing disease in humans; There is an amazing ability to catch pests.
Therefore, it can better control farmland damageGreatly improve the yield of crops, while reducing the use of chemical pesticides, to achieve biological control, and protect the ecological environment. The protection of frogs is also the protection of the farmer, which is also a precious natural heritage and a condition for human survival.
Parasites migrate in the human body and cause damage to all parts of the body, especially the muscle tissue; Where the parasite rests during migration, abscess nodules form; When it travels to the nervous system, it can cause inflammation of the brain and spinal cord. There have been fatal cases of eosinophilic cerebrospinal cord inflammation caused by the worm in China.

Animals that can live both in water and on land are not necessarily amphibians, such as snakes, turtles and other animals that can live in both water and land are reptiles;
Amphibians are a group that transitions from aquatic to terrestrial life, rightly;
The larvae of amphibians live in the water and breathe with gills; Adults can live on land or in water, breathe with gills, ** assisted breathing correct;
Amphibian larvae breathe with gills, adults breathe with lungs, and ** assists breathing, correct so choose: d
I think anyone is 2000, it should be A, because he must be able to live in the water and on land, but you must also have a part of it that lives in the water when you are young, and lives on land when you mature, in fact, both of these are amphibious.
Amphibious assault ships are not aircraft carriers, but in low-intensity operations, amphibious assault ships can replace aircraft carriers to perform some tasks, such as attacking surface ships, air defense and ground attacks, etc. (after all, there are several short-range take-off and landing aircraft and armed ***), but after all, the main task of amphibious assault ships is to find and deliver landing equipment to support amphibious landing, and the main task of aircraft carriers is to obtain sea supremacy.
The world's largest amphibian - the giant salamander In the mountains and streams of the middle and lower reaches of the Yangtze River, the Yellow River and the Pearl River in China, the world's largest amphibian lives - the giant salamander. Its appearance suddenly looks a bit like a child, and its cry resembles a child's cry, so it is generally called a baby fish. It is a precious animal endemic to our country. >>>More
