On The Origin Of Species

This foundational text of evolutionary biology introduces the theory of natural selection—the process by which organisms better adapted to their environment tend to survive and produce more offspring. Darwin presents a wealth of evidence gathered during his travels on the HMS Beagle, arguing that species are not immutable but evolve over generations from common ancestors. This specific edition uses the text from the sixth edition (1872), which was the last version updated by Darwin during his lifetime and includes his final amendments.
