French De l'origine des espèces This Etext was prepared by Ebooks libres et gratuits "De l'origine des espèces" by Charles Darwin is a scientific publication written in the mid-19th century. This groundbreaking work explores the concept of evolution, presenting the idea that species are not immutable creations but instead evolved from common ancestors through a process of natural selection and variation. Darwin's theory challenged the prevailing beliefs of his time regarding the origins and classification of living organisms. The opening of the text sets the scene for an extensive exploration of the history of thought surrounding species' origins, highlighting significant earlier theories and contributions made by notable naturalists, such as Lamarck and Buffon. Darwin discusses his motivations for writing the book, emphasizing the culmination of years of research and observation following his voyage on the Beagle. He aims to provide a rigorous and evidence-backed framework for understanding the gradual modifications of species, drawing from examples in both domesticated and wild organisms, and outlining the core principles that will be elaborated upon in subsequent chapters.
