1) Fossils — show the order of organisms through time and reveal transitional forms, letting scientists place species on an evolutionary timeline.
2) Comparative anatomy — homologous structures (same bones/organs with different functions) indicate common ancestry, while analogous structures do not.
3) Embryology — similar patterns of early development in different species suggest descent from a common ancestor.
4) Molecular evidence (DNA/proteins) — sequence similarities and differences provide a measurable record of relatedness and divergence times.
