Sweet potato (a root modification) and potato (a stem modification) both store food underground in a similar way. They are an example of:
A{'text': 'Homologous organs evolving by divergent descent from a common ancestor', 'label': 'A'}
B{'text': 'Analogous organs evolving by convergent evolution under similar pressures', 'label': 'B'}
C{'text': 'Vestigial organs retained from an ancestral storage-organ lineage', 'label': 'C'}
D{'text': 'Atavistic structures reappearing after long evolutionary suppression', 'label': 'D'}
Answer & Solution
Correct answer: B. {'text': 'Analogous organs evolving by convergent evolution under similar pressures', 'label': 'B'}
Sweet potato and potato have different anatomical origins (root vs. stem) but a similar storage function shaped by similar habitat pressures. Similar function with different anatomical origin is analogy, the outcome of convergent evolution.
