Document Summary
Evidence from the fossil record, historical biogeography, comparative morphology and molecular biology that support the idea of descent with modification from a common ancestor: descent with modification: evolutionary alteration and diversification of ancestral species. A tree, each limb represents a body plan suitable for a particular way of life: fossil record: layers of fossils represent organisms from long ago and there is progressive change in layers. Fossils document continuity and provides evidence of ongoing change in biological lineages: historical biogeography: study of geographical distributions of plants and animals in relation to their evolutionary history. Species on oceanic islands closely resemble species on nearest mainland: comparative morphology: analyses of the structure of living and extinct organisms are based on comparison of homologous structures. Vestigial structures: no apparent purpose, resemble similar functional structures in other related species. Characteristics of a scientific theory and the importance of falsifiability: hypothesis/hypotheses about some phenomena supported through research.
