The Origin of Species by Charles Darwin — cover

The Origin of Species

The Origin of Species is a book of scientific literature written by Charles Darwin and published in 1859.

It is one of the forerunners of scientific literature and the foundation of the theory of evolutionary biology. It can be considered the most influential and historically important work in the field of natural sciences.

The main theme of the book is the concept of natural selection: species evolve over generations, giving rise to today's diversity through a branching pattern of evolution. Although it was not the first evolutionary theory in this regard, it was the first that convinced the entire community about the development of life and eliminated the idea of ​​a creator of animal and plant species. This led him to receive numerous criticisms and protests from the Church by colliding head-on with the idea of ​​God as the creator of the world.

In summary, Darwin's theory explains that the individuals of a species that best adapt to the environment in which they live are those that have a greater advantage and therefore survive, transmitting their genetics to their offspring, and with the passage of many generations, these small adaptations are added to create a new species.

From The Origin of Species

The forms of life throughout the universe become divided into groups subordinate to groups.

Man selects only for his own good: Nature only for that of the being which she tends

575

One general law, leading to the advancement of all organic beings, namely, multiply, vary, let the strongest live and the weakest die.

557

The laws governing inheritance are for the most part unknown.

Nothing is easier than to admit in words the truth of the universal struggle for life, or more difficult--at least I have found it so--than constantly to bear this conclusion in mind.
