How did Darwin embark on the road of studying species

Charles Darwin was an outstanding British biologist in the19th century, the founder of the theory of species origin and development, and the founder of the theory of biological evolution. He discovered the law of biological development and proved that all species have the same ancestor. Darwin's great discovery is of epoch-making significance to biology and has completed a great revolution in science. Engels called Darwin's theory of evolution one of the three great discoveries of natural science in19th century, an outstanding British biologist in19th century, the founder of the theory of species origin and development, and the founder of the theory of biological evolution. Prove that all species have the same ancestor. Darwin's great discovery is of epoch-making significance to biology, completing a great revolution in science and ending the period of idealism and metaphysics in the field of biology. It has a great and far-reaching impact on modern biological science. Engels called Darwin's theory of evolution one of the three great discoveries of natural science in19th century. Darwin was born in a family of doctors in Shrewsbury on February, 2009 1809. He likes natural sciences, such as natural history and chemistry, since he was a child. In 2008+0825, I went to the University of Edinburgh to study medicine. He studied two kinds of aquatic organisms and made some interesting discoveries, so he read his first two papers at the Pliny Society, an academic group in his school. He was only 17 years old at that time. Since Darwin had no intention of studying medicine, his father sent him to Cambridge University to study theology on 1928. 183 1. After graduation, he took part in a five-year round-the-world trip on the survey and research ship Beagle, which was of decisive significance to Darwin. The fact that a large number of species mutate in South America and other places makes him doubt the Bible. He further realized that species are changeable. As a result, he gradually got rid of the shackles of creationism and firmly embarked on the road of believing in science and pursuing truth. After returning to China, Darwin began to conduct a comprehensive and systematic study on the origin of species. He collected a lot of scientific facts, studied predecessors' works and participated in social production practice. Summarize the experience of working people at home and abroad in cultivating new varieties (there are more than 100 valuable experiences of working people in ancient China directly quoted or mentioned in his works as evidence of his theory). After 22 years of persistent concentrated thinking and comprehensive research, Darwin finally published his masterpiece The Origin of Species on1859165438+1October 24th. He founded the theory of evolution. He believes that the biological world is gradually changing from simple to complex, from low to high. Darwin's theory of evolution is a cannonball to create The Theory of Everything against "God", which puts biology on a complete scientific basis for the first time. Darwin (1809-1882)1909.02. Darwin was born in Shrewsbury, England. His grandfather and father are both famous local doctors. His family hopes that he will inherit his ancestral business in the future. 16 years old, was sent to the University of Edinburgh to study medicine. But Darwin loved nature since he was a child, especially like hunting and collecting minerals and animal and plant specimens. After entering medical school, he still often collects animal and plant specimens in the wild. His father thinks he is "idle" and "idle". In a rage, 1828, he was sent to Cambridge University to study theology, hoping to become an "outstanding priest" in the future. Darwin was very tired of the fallacies of creationism in seminary. He still spent most of his time listening to lectures on natural science and taught himself a lot of natural science books. He is keen on collecting beetles and other animal and plant specimens, and is full of keen interest in the mysterious nature. 1828 One day, in a forest outside London, a college student wandered by an old tree. Suddenly, he found that there were bugs crawling under the bark that was about to fall off, so he quickly peeled off the bark and found two strange beetles, which were crawling forward quickly. The college students immediately drew their bows from left to right, grasped them in their hands and looked at them excitedly. Just then, another beetle jumped out of the bark, and the college students were caught off guard and quickly hid the beetle in their mouths. Reached out and caught the third beetle. Looking at these strange beetles, the college student really couldn't put it down. He just envied the beetle in his hand and forgot which one was in his mouth long ago. The beetle in his mouth couldn't stand it, so he released a spicy venom, which stung the tongue of college students. He remembered the beetle in his mouth and spit it in his hand. Then, regardless of the pain in his mouth, he proudly walked to Cambridge University in the city. This college student is Charlie Darwin. Later, in order to commemorate the beetle he first discovered, people named it "Darwin". 183 1 year, Darwin graduated from Cambridge University. He gave up his high-paying career as a priest and remained keen on natural science research. In this year 12, the British government organized the warship beagle to explore the world. Darwin was recommended by others as a "naturalist" to take a boat at his own expense and began a long and arduous expedition around the world. Everywhere Darwin went, he always made serious investigations, interviewed local residents, and sometimes asked them to be guides, climb mountains and wade, collect minerals, animal and plant specimens, and excavate biological fossils. Many unrecorded new species have been discovered. He collects grain rock samples and animal fossils during the day and is busy recording the collection process at night. 1832 10, the beagle docked at Santiago Island in the Cape Verde Islands in the Atlantic Ocean. The sailors all went to investigate the direction of the sea. Darwin and his assistant climbed the mountain with backpacks and geological hammers to collect rock samples. Why do they keep changing during the investigation? What is the connection between them? These questions became more and more profound in his mind, which gradually made him doubt creationism and species invariance. 1832 At the end of February, Beagle arrived in Brazil. Darwin went ashore for an inspection and proposed to the captain to climb the Andes in South America. When they climbed the mountain more than 4000 meters above sea level, Darwin accidentally found shell fossils on the top of the mountain. Darwin was very surprised. He thought, "Underwater! After repeated thinking, he finally understood the truth of crustal rise and fall. Darwin's mind churned and he got a better understanding of his conjecture: "Species are not static, but change with different objective conditions! "Later, Darwin crossed the Pacific Ocean, passed through Australia, crossed the Indian Ocean, bypassed the Cape of Good Hope, and returned to England in June 1836+00. During his five-year exploration around the world, Darwin accumulated a lot of information. After returning home, he sorted out information, practiced deeply and consulted a large number of books to find a basis for his biological evolution theory. 1000000006 He wrote the outline of the Origin of Species for the first time. 10, Darwin's scientific masterpiece The Origin of Species, written after more than 20 years of research, was finally published. In this book, Darwin clearly put forward the viewpoint of "evolution", indicating that species are constantly changing, from low to high, from simple to complex. For the first time, biology was established on a complete scientific basis, and creationism and species invariance theory were overthrown with a brand-new idea of biological evolution. The Origin of Species is a masterpiece of Darwin's theory of evolution, which marks the formal establishment of the theory of evolution. The publication of the Origin of Species caused a sensation in Europe and even the whole world. It dealt a heavy blow to the foundation of theocracy, and all reactionary churches and feudal literati were furious. They got up and attacked it. Defaming Darwin's theory of "blaspheming the Holy Spirit" runs counter to "sacred rights are endowed with justice" and is against human dignity. On the contrary, the progressive scholars represented by Huxley actively promoted and defended Darwinism, pointing out that the theory of evolution blasted people's ideological imprisonment and inspired and educated people to liberate themselves from the shackles of religious superstition. Then Darwin began to write his second masterpiece, Variation of Animals and Plants at Home. Based on indisputable facts and rigorous scientific judgment, this paper further expounds his views on evolution, puts forward important arguments such as species variation and inheritance, biological survival competition and natural selection, and soon published this masterpiece. In his later years, Darwin stubbornly persisted in scientific research and writing with amazing perseverance, and published many works such as The Origin of Man. Darwin himself thought that "the main pleasure and the only career in his life" was his scientific works. Some of the most important scientific achievements were obtained through direct investigation during his travels, such as Darwin's famous Investigation Diary, Geology of Beagle and Zoology of Beagle. In his works, The Origin of Species is of great historical significance, which shows the gradual development of Darwin's theory of evolution and natural selection. The publication of the Origin of Species is a great event. Because the publication of "Origin of Species" indicates that the views of most learned people on the biological world and the status of human beings in the biological world have undergone profound changes in the19th century. The publication of the Origin of Species has aroused fierce attacks on Darwin's theory by creationists and teleological scientists (but these people account for the vast majority), and also caused corresponding struggles to maintain Darwinism. In addition to Darwin himself, progressive naturalists actively participated in this struggle. They became enthusiastic supporters of Darwin's theory everywhere. On April 1882, the great scientist died of illness, and people buried his body next to Newton's tomb to show their respect for the scientist.
