The original book "On the Origin of Species" which changed the course of scientific understanding and transformed humanity's comprehension of their place in the world – and remains controversial to this day.

First published in 1859, On the Origin of Species introduced Charles Darwin's theory of natural selection to the world and, consequently, the role of evolution in biological development and the emergence of species. By observing that species evolved over vast periods of time, Darwin was able to articulate foundational ideas such as common ancestry, the struggle for survival, and inherited variation.

Multifaceted and deeply provocative for 19th-century audiences, the implications of natural selection resonated across religion, philosophy, the arts, and of course, the scientific community. Based on years of observations and written for a general audience, On the Origin of Species is a classic work that truly changed the world.
