Evidence for large-scale evolution (macroevolution) comes from anatomy and embryology, molecular biology, biogeography, and fossils. Similar anatomy found in different species may be homologous (shared due to ancestry) or analogous (shared due to similar selective pressures).
Three types of evidence support evolution and natural selection: structural, microbiological, and direct observation. Structural evidence encompasses homologous structures and the fossil record. Microbiological evidence involves DNA similarities and shared processes across species.
