In The Origin of Species, Charles Darwin argues that all species of life have descended from a common ancestor. He provides evidence for this claim through observations of the fossil record, the geographical distribution of plants and animals, and the similarities between species. He also proposes a mechanism for how new species can arise, through a process he calls natural selection.Darwin’s theory of evolution by natural selection is one of the most important scientific theories of all time. It explains the diversity of life on Earth and the continual change that is taking place. It is the foundation for all of modern biology, and has revolutionized our understanding of the natural world.
