What is the origin of the species? What is the main content of On the Origin of Species ?

After many years.

Darwin began to sort out information on the origin of species in 1837, and in November 1859, Darwin's book "On the Origin of Species", which Darwin had painstakingly studied for many years, was officially published.

The book cites a large number of facts to prove that living things evolve, that species are changing, that new species are constantly being created, and that old species that cannot adapt to environmental changes are constantly becoming extinct. The various living organisms that exist have developed from a common ancestor. Darwin used natural selection as a theoretical basis to explain the mechanism of biological evolution.

In the course of historical development, natural selection is a major factor in biological evolution due to the accumulation of favorable variations, which lead to the formation of new species.

Darwin put forward two theories in On the Origin of Species:

1. He believes that all animal and plant objects have evolved from earlier and more primitive forms;

2. He believed that biological evolution came through natural selection.

Its theoretical highlights are as follows:

1. Species are not static, but will change with environmental changes;

2. The evolution of organisms is a slow change that is continuous over a long period of time, not a sudden drastic change;

3. The same type of organisms have a common ancestor, for example, mammals evolved from the same ancestor;

4. The biological group will expand with reproduction, and exceed the limit of its living space and food, causing competition between individuals;

5. The disadvantages of not adapting to the environment will be eliminated, and the fittest can survive and reproduce.

5. Individuals who do not adapt to the environment will be eliminated, and only those who are weak and fit can survive and reproduce.

D480 "Origin of Species" & English Learning Review.

The next book I plan to read is "The Origin of Species", which was translated by Mr. Shu Degan of Peking University.

The reasons for choosing this book and this edition are as follows:

1.As I progressed in my studies, I developed a strong interest in anthropology and evolutionary history, and it is difficult to understand a person who does not know his past. In the same way, in order to understand true human nature, it is necessary to understand the history of human beings, otherwise there is no way to know human nature, let alone stand on the high ground of morality to judge human nature at will.

2.Based on the previous "Animal Farm" color book collection, the visual shock brought by the color book, this version with color pictures was selected, text + images, which made people's memory and understanding more profound.

3.Mr. Shu Degan is an academician of the Chinese Academy of Sciences, and his resume, respect for science, and understanding of scientific thought deeply moved me, allowing me to see how a real scientist is to study, how pious and attentive, and not allowing a trace of almost sloppiness. In fact, it has also proved that this choice is right, even if I look at the preface, it has made me respect and benefited a lot.

4.Darwin's theory**, Darwin's family history, further illustrates the importance of the environment and the importance of inheritance.

2021 is coming to an end, so it's time to do a review of English learning in 2021 and make plans for next year.

1.After translating the first fully English book "Be Loved, Money Will Come", read a few books on how to translate, and tried to watch English movies, and found that none of them were particularly suitable for me. In the end, I returned to the goal of cognition and growth, and chose Chinese-English comparative learning, but I didn't expect it to bring a lot of surprises.

There are original and translated English books, which are basically very classic, such as "Effective Manager" and "Animal Farm", which reduces my selection costs, and allows me to read more classic and more original books, and my cognition and growth are multiples.

At the same time, in the process, I found a way to choose Chinese and foreign books. In the fields of science and philosophy, foreign research is more in-depth than ours, while in the field of human nature and humanities, the things of our ancestors are no worse than those abroad, and even more thorough.

Therefore, when choosing to read books in English, you can give priority to this type of books, and other types of books, so as to read the classics handed down by our ancestors first, such as the Four Great Classics, the Twenty-Four History, Mao Xuan, and so on.

2.Next year's plan is very simple, focusing on the classics to improve cognition, supplemented by learning English. And in the process of learning, I found that these classic books, their original English books, are really easy to understand, the sentences are not very complicated, and there are not so many rare words, which is also the real everyone, they have the ability to explain the profound truth very simply.

Preliminary books "On the Origin of Species" and "The Wealth of Nations" Try to read Shakespeare's ** again, or come across other more classic books.

The full title of "On the Origin of Species" is "On the Origin of Species by Natural Selection (i.e., the Preservation of the Good Race in the Struggle for Survival)". The book is divided into 15 chapters, with the exception of the "Historical Overview" and the "Introduction" at the frontispiece. This work not only proves that organisms evolve with a large number of scientific facts, but also puts forward the "theory of natural selection" to explain why organisms evolve, which is very convincing, lays the foundation for the scientific theory of evolution, and has a huge and far-reaching impact in the academic world.
