Document Summary
Evolution can be defined by darwin"s phrase descent with modification. Their spots help them survive in desert. Fossils are remains or traces of organisms from the past, usually found in sedimentary rock, which appears in layers of strata. Younger fossils are found higher up in the strata. Darwin hypothesized that species from south america had colonized the gal pagos and speciated on the islands. Natural selection is a process in which individuals with favourable inherited traits are more likely to survive and reproduce. The match between organisms and their environment. It refers to the view that all organisms are related through descent from an ancestor that lived in the past. More diverse the environment, the more opportunities there are for evolutionary change to create new species. Blue feet is an honest indicator of good health. Only one finch species started on the island. Average beak size increased by 4% after the drought bigger beaks could get more food.
