Document Summary
Earth was wet and moist, spread of temperate and tropical forest. Earth was dry and arid, forest gave way to plains and savanna areas. At least one group adapted to life increasingly on the ground. Savanna environment played crucial role in triggering changes that led to human development. Single most important theory ever developed in world of science. Explanation of all living things ultimately depend on evolutionary theory. Subdivision of a species that exists in a moment in time as a reproductive unit. Development of human populations from earlier populations over long periods of time and in response to pressure in their environment. Charles darwin used factors to form theory. Geology- new ideas of an old earth, fossils. Population statistics- species will overpopulate food supply, struggle for existence . Natural history- global explorations led to new discoveries of plants and animals, variation between and within species.
