Document Summary
If you were to stay in a dark room for a long time, you would become fertile offspring. Captain robert fitzroy for a 5-year around the world voyage on the beagle: his interest in geographic distribution of species was kindled by a stop at the, his focus on adaptations. Galapagos islands near the equator west of south america. In reassessing his observations, darwin perceived adaptation to the environment and the origin of new species as closely related processes. From studies made years after darwin"s voyage, biologists have concluded that this is indeed what happened to the galapagos finches: he developed two main ideas. Descent with modification explains life"s unity and diversity. Natural selection is a cause of adaptive evolution. Members of a population vary greatly in their traits. Traits are inherited from parents to offspring. All species are capable of producing more offspring than the environment: observation 1, observation 2, observation 3 can support, observation 4 survive, natural selection.
