In short
Charles Darwin published On the Origin of Species on November 24, 1859, presenting scientific evidence that species evolve through natural selection rather than divine creation. The book fundamentally challenged prevailing religious and philosophical assumptions about humanity's place in nature, sparking debates that persist today.
How it unfolded.
The five-minute version
What actually happened.
Etiology is the study of causation or origination. The word is derived from the Greek word αἰτιολογία (aitiología), meaning "giving a reason for". More completely, etiology is the study of the causes, origins, or reasons behind the way that things are, or the way they function, or it can refer to the causes themselves. The word is commonly used in medicine and in philosophy, but also in physics, biology, psychology, political science, geography, cosmology, spatial analysis and theology in reference to the causes or origins of various phenomena.

"On the Origin of Species by Means of Natural Selection - Mr. Darwin's New Work"
Mr. Charles Darwin has at length given to the world the results of his twenty years of investigation into the origins and transmutation of species. His theory, grounded in extensive observation during his voyage aboard the Beagle, proposes a mechanism by which all living creatures descend from common ancestors through natural selection.
