Question

Select ALL the correct answers.
The diagram below shows the similar limb structures of a dolphin, a horse, and a bat. Similar bones are highlighted in the same colors.



Which of the following is true about these three species?

All three species have not adapted since their existence.
All three species should be classified within the same genus.
All three species share a distant common ancestor.
All three species evolved over time to best fit unique environments.

Answer 1

Correct choices:
- All three species share a distant common ancestor.
- All three species evolved over time to best fit unique environments.

Explanation: The similar bone structures are homologous, showing descent from a common ancestor and subsequent divergent evolution (adaptations for swimming, running, and flying). The other two statements are false: the species have adapted, and they belong to different genera.
