Question

the forelimbs of mice, bats, and whales all have a similar bone structure. this is an example of which type of evidence of shared ancestry? embryonic structures vestigial structures homologous structures adapted structures

Explanation:

• Embryonic structures: Focus on similarities in embryo development, not adult bone structures.
• Vestigial structures: Are remnants with no/little function, not about similar bone structures.
• Homologous structures: Similar bone structure (same origin, different functions) as in mice, bats, whales' forelimbs.
• Adapted structures: Not a standard term for this evolutionary evidence type.

Answer:

homologous structures
