It is a gradual process, not observed in a single individual. C18th erasmus darwin suggested all species arose from evolution mechanism. C19th discovery of fossils convinced naturalists that extinctions had occurred-support for evolution (maybe our planet is older than we thought) 1809 jean baptiste lamarck suggested inheritance by acquired characteristics". Use/disuse body parts results in organisms developing certain traits that can then be passed on to their offspring. Species do evolve as a result of organism"s interaction with their environment.
