Document Summary
Key work for modern biology: charles darwin"s on the origin of species. Evolution is the most influential theory in the biological sciences o. Evolution: to gradually undergo orderly change: darwin was the first to collect evidence to support evolution and the first to suggest how evolution works. Documented through more recent geological layers the evolution of fossils. Described structural similarities between living species, suggesting they evolved from a common ancestor. Changes seen in plants and animals through selective breeding. Rapid evolution seen over one season of drought in the finches of the gal pagos islands: argued that natural selection causes evolution. Heritable traits with higher rates of survival and reproduction are the most likely to be passed on to future generations. Fitness: the ability an organism has to survive and reproduce to pass on genes to the next generation. After generations, a species will have evolved to be better adapted to its particular environment.
