Vestigial structures (e.g., human appendix, whale pelvic bones) are evidence for
- A
Future adaptation — these may regain function in descendants under new selective pressures
- B
Convergent evolution — these arose independently in different lineages and serve similar functions
- Ccheck_circle
Common ancestry — these were functional in ancestors but no longer serve their original purpose
- D
Recent mutation — these formed in modern populations and have not yet evolved a function
Explanation
Vestigial features are remnants from ancestral lineages; their existence makes evolutionary descent the most parsimonious explanation.
