Evidence for a common ancestor: Similar structures may arise independently, while apparently different structures, such as a human hand and a whale's flipper, are related. WebEvidence 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). Molecular similarities provide evidence for the shared ancestry of life.
