"On the Origin of Species in the Animal and Plant Kingdom by Means of Natural Selection" is the fundamental work of the great British naturalist Charles Darwin, which changed our understanding of evolution and fought against traditional religious concepts of the creation of the world. In the book, the author explains the principles of natural selection and the mechanisms of evolution of living species. Using examples and observations from nature, Darwin proves that all species of plants and animals arose through gradual changes over time. This book not only opened a new science - evolutionary biology, but also became one of the most influential and valuable works in world scientific literature.
