Detailed Solution
Download Solution PDFThe correct answer is By comparing the anatomy.
Key Points
- Homologous organs are identified by their similar anatomical structures, even if their functions differ.
- These organs are derived from a common ancestor, indicating evolutionary relationships.
- Examples of homologous organs include the forelimbs of vertebrates such as humans, birds, and bats.
- Despite different functions (e.g., grasping, flying), these organs share a similar bone structure.
- Comparing anatomy helps scientists understand evolutionary biology and the development of species over time.
Additional Information
- Analogous Organs
- These are organs that perform similar functions but have different anatomical structures and evolutionary origins.
- Examples include the wings of birds and insects.
- Vestigial Organs
- These are organs that have lost most or all of their original function through evolution.
- Examples include the human appendix and the pelvic bones in whales.
- Evolutionary Biology
- This field of biology studies the evolutionary processes that produced the diversity of life on Earth.It involves the study of homologous and analogous structures to understand the evolutionary relationships among species.
