On the origin of species, Author : Charles Darwin (International Best Seller)

Charles Darwin's On the Origin of Species is a foundational work in evolutionary biology. It introduced the scientific theory that populations evolve over generations through a process of natural selection. Darwin gathered evidence over decades during his travels, most famously during his voyage aboard the HMS Beagle, where observations from places like the Galápagos Islands shaped his ideas. One of the best-selling science books ever published. Translated into dozens of languages. Continues to be studied and referenced in biology, philosophy, and the history of science.
