The Origin of Species
What is The Origin of Species about?
On the Origin of Species (1859) is Charles Darwin’s groundbreaking work presenting the theory of evolution by natural selection. Darwin argues that species are not fixed creations but evolve over time through the differential survival and reproduction of individuals with advantageous traits. Drawing on evidence from geology, paleontology, biogeography, embryology, and domestic breeding, he builds a comprehensive case for evolution as the mechanism driving the diversity of life. The book transformed biology, challenged prevailing religious explanations of creation, and remains one of the most influential scientific works ever published.
