Published in 1859, Charles Darwin's The Origin of Species became known as ''The Book that Shook the World''. Its first edition sold out on the first day, and the same happened with six subsequent versions. To this day, the naturalist's theory of evolution is controversial. According to Darwin, species compete for survival, and those that survive give rise to the next generation, which in turn incorporates favorable natural variations and passes them on hereditarily. Until his death, Darwin tirelessly rewrote his theory, and new research was included in each of the six editions. This is what can be considered his definitive work. Still considered one of the most innovative and challenging biological treatises ever written, The Origin of Species, with its approach to evolutionary processes, shocked much of the Western world when it was released in 1859. In this new edition, readers will come into contact with the most important work on Biology ever written
