In charles darwin"s the origin of species, published in 1859, he proposed two ideas: species change over time and have a common ancestor (they evolve), natural selection is the mechanism that causes these changes. Before darwin, jean-baptiste lamarck proposed the idea of evolution, however he proposed the hypothesis of inheritance of acquired traits. Darwin collected info on his five-year trip aboard the h. m. s. Alfred russel wallace also came up with an idea of natural selection and published aspects of his hypothesis before darwin. Wallace and darwin presented the idea of natural selection in a joint paper presented to the royal society in london in 1858. Greek poet anaximander was the first western philosopher to believe that humans evolved from fish that moved to land. Jean-baptiste lamarck was the first scientist to state that organisms adapted to their environment.
