[urgent! Urgent! Urgent! ] the main points of Darwin's theory of evolution

The main point of Darwin's theory of evolution is that Darwin believes that there is competition for survival among creatures, the fittest survive and the unsuitable are eliminated. This is natural selection.

It is through inheritance, variation and natural selection that organisms evolve from low to high, from simple to complex, and from few to many.

Charles robert darwin, a British biologist, was the founder of the theory of evolution. I once sailed around the world on the ship Beagle for five years, and made a lot of observations and collections on animals, plants and geological structures. He published the Origin of Species and put forward the theory of biological evolution, thus destroying all kinds of idealistic creationism and species invariance. In addition to biology, his theory has a great influence on the development of anthropology, psychology and philosophy.

Engels listed "evolution theory" as one of the three major discoveries of natural science in the19th century (the other two are cell theory and the law of energy conservation and transformation), and made outstanding contributions to mankind.
