In terms of evolution, what do homologous structures indicate?
Common ancestry
Study the structural and genetic evidence of evolution through comparative anatomy, focusing on the differences and similarities in organisms' anatomy. Learn about homologous structures that are similar in structure but may serve different functions, analogous structures with similar functions despite evolving independently, and vestigial structures that have lost their original function.
