the origin of life-mankind

since ancient times, the problem of the origin of mankind has been puzzling people. Myths and legends and religious theories have always made people think that God created man. With the development of science and technology, people continue to know and understand the evolution of knowledge of nature and Darwin's theory, which has gradually been understood and accepted, and has become the theory at that time. However, for a long time, people have never stopped arguing about the origin of life.

The following articles are excerpted from the evolution of life and biodiversity for your reference.

Danish scientists discovered the early forms of life on earth: geological museum, Copenhagen, Denmark Rosen discovered the traces left by plankton in Flamini, western Greenland, more than 3.7 billion dollars ago. This discovery shows that life on earth may have originated as early as $3.7 billion years ago, which made the origin of life a step forward. BR /> Rosen studied, and they found carbon isotopes in two rocks 37 million years ago. The carbon isotopes in ancient rocks are similar to those in modern rock. The rock contains waste discharged by plankton, and it is still. "Beijing Economic News" 99.2.4

Scientists analyzed Greenland rocks and found that there was life on the earth 3.85 billion years ago. On November 4th, AFP in Los Angeles showed that the rocks in Greenland had life on the earth at least 3.85 billion years ago, which was considered as 4 million years earlier than before.

L1 month's magazine Nature said that the rock discovery in Greenland southwest of Amelia Island in Akilov was analyzed in the University of California, Los Angeles, and the results proved the above conclusion.

The scientists involved in the research analyzed from universities, Scripps College in San Diego, California, Earth and Space, California, Los Angeles, Australian National University and University of oxford brookes university.

One day, Stephen Moi of Scripps College even said, "Our evidence eloquently proves that there was life on the earth at least 385 million years ago. Is this the final conclusion? We are likely to find that life existed even earlier. "

Carbide rocks are analyzed by ion probe at the University of California, Los Angeles, USA. This instrument enables scientists to know the exact composition of the samples.

Moiri, even though the discovered life form may have a simple microstructure, it is actually uncertain in shape and nature due to the destruction of high temperature and pressure.

The evidence that existed in the life of William University, a paleontologist in California, in Los Angeles, Schoepf provided a bacterial fossil on the earth 346 million years ago. Reference news 96.11.9

The extraterrestrial life on Earth may come from the day before the announcement by Swedish scientists. Yesterday, astronauts returned to Earth alive after going to Mars, two kinds of bacteria, which means that there is life on Mars.

at a news conference in Atlanta, USA, Mikhail Khodorkovsky of the Royal Research Center for Science and Technology in Stockholm and some other scientists explained that bacteria that are tenacious in experience can withstand high speed, radiation and high temperature, so they live "as a whole".

Scientists also say that it may be the formation step of early life before Mars cools down. If Mars is aimed at the influence of microorganism Mars, microbes attached to the surface of Mars can avoid the gravity of Mars, and the earth or other planets can run. If the microbes can bear the radiation space, they can safely land on the earth for multiplication development.

The life mystery of the CAMBRIAN life explosion

Kunming, China News Service, April 17th: Recently, according to tens of thousands of animals in Guizhou, China scientists: The life of the CAMBRIAN life explosion 4-58 million years ago, animals were divided and many "grown-up animals" appeared, thus initially solving the mystery of the CAMBRIAN explosion that has long plagued the paleontology world.

Experts pointed out that the discovery of the origin of animals, including the history of human and animal diversity, was pushed forward more than 5.8 million years ago, when it was a prelude to the Cambrian life explosion like Weng 'an fauna.

54-53 million years ago, in the Cambrian, the explosive force of many animals appeared, and the earth suddenly squeezed together, which was the Cambrian explosion. There are very few animals with Precambrian fossils. Due to the lack of fossil records of life, the cause of the explosion is still a mystery. What was the world before the Big Bang? Then what happened ... the series touched the skeptical hearts of countless paleontologists.

According to Xinhua News Agency, in 1998, researcher Chen Junyuan of Nanjing Institute of Geology and Paleontology discovered in Guizhou and South China. Up to now, the earliest known multicellular sponge and its embryo fossils shocked the world 58 million years ago.

In addition to sponge fossils, scientists have discovered a large number of embryo fossils of two germ-layer animals for the first time. Symmetrical jumps on both sides in the history of life evolution. Animals with complex directions from the original radial symmetry to bilateral symmetry have head and tail, and the development of nerves, which may have evolved into human advanced animals. These Weng 'an are bilaterally symmetrical, making them the earliest bilaterally symmetrical animals in the world so far. (after the pop-up life)

Quan, when will life begin on earth? A boiling deep-sea volcanic fountain suddenly brought about by the ups and downs of ocean currents in shallow tides? Such a big problem has been puzzling scientists.

Recently, 25 scientists from nine countries boarded a ship named "Julius Choice" to inspect drilling holes and stumbled upon important clues, revealing the mystery. This event detected 24 kilometers under the sea, west vancouver island, Canada, removing the core, drilling in the sea, mineral and biological resources and storage. However, this time, the drilling reconnected and opened the underground hydrothermal RIP. Look at the hot water sprayed from the inside out at up to 29 degrees Celsius.

Scientists attracted by natural hot springs on the seabed can find new ocean floor surface layers in copper, zinc, manganese and other metal deposits because of the benefits formed in iron, which can be studied through this channel. More importantly, these deposits seem, even if the geological structure formed may be related to the origin of life itself. In this process, the geological structure formed, the continental drift collided and pulled the block for a long time.

crustal cracks caused by plate movement. If these cracks appear on the seabed, water will penetrate into them. When seawater is in hot volcanic rocks, it becomes very hot, and then it goes through hydrothermal vents, the ocean of these minerals. After millions of years of geological structure and sedimentation, the final reasons for these deposits are as follows.

If so, it can be considered as a newly discovered crack, which provides some clues to uncover this ancient mystery. Biological hydrothermal reaction time is limited, so how can we have enough time to develop in such a hot environment? If you don't have enough time, will they be another tearing gap?

melanie, a microbiologist at the University of Washington? The Vancouver Summit RIP may provide some? The answer. She said: "Now, we can look at the biological occupation in these places from the beginning. This is the first opportunity to observe the new hydrothermal RIP. In this environment, due to the rapid growth of animal communities, time has developed and changed. "

Some scientific research teams will use underwater robots to study the gap between geology, chemistry and biology, and they have also installed some equipment to monitor the temperature and pressure nearby. These data will be stored in the underwater computer and then turned on, so after several years of exploration. China Ocean News "97.1.1O/Sequoia

Why is the only gender on the earth British scientists believe that life on the earth is the only female and male, and about 2, years ago, our ancestors were infected by bacteria.

There are countless life forms on the earth. Why are most species only male and female? This problem has been puzzling scientists all over the world for many years.

Mushrooms with 36OOO genders are sterilized, a strange creature called Myxomycetes with 13 genders, but these animals only live on the earth and are divided into male and female genders. Rare exceptions are almost universally applicable laws, and this phenomenon raises a mysterious and evolutionary problem of life. The sex and mating of 1O on earth with any species, then the probability of life on earth finding a partner in its surrounding environment will reach 99%.

It can only be said that it seems that the survival of biological sex species is difficult rather than easier. Then, why is it the only sex on earth? Hearst believes that this is entirely due to how life on earth is specific through genes, which are called mitochondrial genes. The nucleus or the central part of the cell (different mitochondrial deoxyribonucleic acid (DNA)) carrying this gene can quickly replicate itself.

It looks like some kind of bacteria from which mitochondria come. The free replication of mitochondria is left by their bacterial ancestors.

Mitochondrial DNA can replicate rapidly. If 99% of the earth's organisms mate with the same species, any mutation in mitochondria is likely to shut down quickly by spreading. Mutation is harmful, so the consequences of mutation may be catastrophic. Finding a mate may be difficult for other species on earth. However, from an evolutionary point of view, the benefits of this kind of reproduction can reduce the mutation. People found living in Britain, the United States, Russia and others at the bottom of the Antarctic glacial lake

The country is preparing to go to the largest subglacial lake in Antarctica-"Oriental Lake" * * * Together with exploring scientists, they plan to dig through the original 4m ice on the surface of the East Lake for two years. It is reported that a similar device may be used in the future to detect the "East Lake" ice drilling machine, which was developed by NASA in search of the satellite living in Jupiter.

Scientists have found thick ice on Europa and want to live under the ice. NASA says that the "East Lake" exploration program provides a good opportunity to test Europa's ice drill access equipment in the future.

The scientists involved in the project said that "Dongqian Lake" is a possible form of low life for cattle. At present, the inspection team has tried to drill dozens of square meters of huge ice blocks, covering the surface of the "East Lake", and found some microbes that have never been seen before. Scientists pointed out that the bottom of the "East Lake" lake is the most closed social environment on the earth, which was formed at least 2 billion years ago, which can save the preservation of the original life forms and the fact that the earth where life evolved is completely fragmented, providing new clues for studying the origin of life on the earth.

In addition, if we can find the creature in the "East Lake", it proves that his life may be immortal in a completely closed environment, which will also be the possibility that scientists can determine. The important basis of Darwinism of China Association for Science and Technology "98.4.26" living in Europe and other planets under the ice is not worth believing, which was published by Professor Lu Yingzhong in December 1977. > The article, and firmly believe that evolution is wrong. " For more than 2 years, I published the Cosmic Life Science and Philosophy, and Darwin's Theory of Evolution "put forward a very scientific criticism

Min She En national business daily". Lai Huiyun reported the evolution of Darwin's theory published by French biologist Lei Mi-box recently, which was published in 1998. For 1 years, scientists have not only been able to continue to put forward this theory, but also begun to doubt its authenticity. This evolutionary theory of the National People's Congress, which has long been opposed, is exciting. Xia Wen said that the theory of Genesis tells us that everything was created by God, but God no longer created it, and we have no way to know that this theory is correct. The greatest achievement of Darwin's theory is that a scientific study began with the origin of life, living for more than 1 years? The world has a deeper understanding, but it cannot prove the truth of Darwin's theory.

octopus and squid live in the deep sea. In their living environment, in the dark, most fish are blind, but they live a very comfortable life. The eye structure of octopus and squid is similar to that of human eyes. Why did they start? Kai puzzle, in the dark environment, what is a pair of dazzling? The living environment is the same, why are there two completely different adaptation methods? It can be seen that the emphasis on survival in an environment that conforms to the theory of "survival of the fittest" is not necessarily true < P > Another example is parasitic on the liver of sheep, clonorchiasis. Each female insect lays about 15 million eggs, and the feces of the eggs are discharged, and then snails must crawl, and the eggs attach to snails. Plants are transplanted through snails, and then the liver fed by sheep factories in this process can be multiplied by about 1.5 billion eggs and a dozen eggs. It is simply a breeding process.

The lazy action of living trees in Australia is to slowly excrete and climb to the earth, which is very ridiculous. The land excreted by them helps to increase the number of trees, but because of its slow movement, ground predators are easy to succeed. It is unreasonable to risk one's life by excreting. Many actions and plant breeding and survival processes. It's very similar to this unreasonable situation. According to the natural selection table, we cover up our tracks for a long time, but the time is longer than that of the human world, and the dynamic structure of many plants in millions of years has not significantly changed the principle of "natural selection, survival of the fittest". It's just a myth that we can't prove as God's creation.

In addition, according to Darwin's theory of evolution, there should be several stages in the complex process of biology, but on the basis of fossil research, the background of evolution is still impossible to establish. Many physicists and biologists began to think that there is a purpose in the universe. He said that he did not propose the direction to God, a computer program, a simple program, and often unexpected development. It often happens, especially when the computer's internal logic design has unnecessary reactions, and our world may have programs.

I believe that in the next century, the fallacy of evolution will be proved, but at that moment, many scientific scholars will oppose me, but I must say, "Time will prove that I am right!

Life Science The birth of a new Earth Life Australian scientists found evidence that the earth was a primitive life form 27 million years ago. Researchers said that their research found that molecular fossils preserved the world's first biomolecule, which is evidence of life when the earth was just born.

Researchers from Nanjing Institute of Geology and Paleontology, Chinese Academy of Sciences, Sun Ge and scientists from China recently discovered that the first flower in the world, Liaoning Guguo, was an angiosperm in beipiao city and Liaoning province 145 million years ago, which is considered to be the oldest flower in the world. People in the most prosperous group of angiosperm kingdom eat wheat, rice, cotton, linen, and wear Youmeilin.

The research of the international joint research group of ancestor scientists shows that 45 million years ago, all the plants on the earth had the same ancestor and a needle-sized original plant.
