Though Darwin’s ideas were modified by later developments in genetics and molecular biology, his work remains central to modern evolutionary theory. His many other important works included Variation in Animals and Plants Under Domestication (1868) and The Descent of Man…
Darwin's theory of evolution by natural selection, with its tree-like model of branching common descent, has become the unifying theory of the life sciences. The theory explains the diversity of living organisms and their adaptation to the environment.
Darwin's theory of evolution by natural selection underlies all modern biology. It enables us to decipher our genes and fight viruses, as well as to understand Earth's fossil record and rich biodiversity.
