The Origin of Species

Charles Darwin's groundbreaking work of evolutionary biology, The Origin of Species introduces the scientific theory of evolution, which posits that species evolve over a period of many generations through a process of natural selection. Darwin's theories have been widely embraced by the scientific community as fact and have laid the foundation for subsequent major advances in the field of biology. It is arguably one of the most important scientific treatises ever written. This is the sixth edition of the formative text of evolutionary biology.
