Document Summary
Define evolution: change of allele frequency over time/ darwins phrase descent with modification. Darwin noted that current species are descendants of ancestral species. Evolution can be viewed as both a pattern and process. 19. 1: the darwinian revolution challenged traditional views of a young earth inhabited by unchanging species. James hutton and charles lyell: geologists james hutton and charles lyell perceived that changes in earth"s surfaces can result from the study of fossils largely developed by georges cuvier slow continuous actions still operating today. Lammark"s hypothesis: hypothesized that species evolve through use and disuse of body parts and the inheritance of acquired characteristics, the mechanisms he proposed are unsupported by evidence. 19. 2: descent with modification by natural selection explains the adaptations of organisms and the unity and diversity of life. Darwin"s research: had a consuming interest in nature, and studied medicine and then theology at cambridge.
