Evidence of evolution: anatomy

Explore how scientists study anatomical features of modern organisms to infer evolutionary relationships. Understand how homologous features indicate shared ancestry, while analogous features evolve independently. Describe how comparing physical traits—both in living species and fossils—helps determine relatedness and reveals how species have evolved over time.
