Match each anatomical structure on the left with its corresponding category of evolutionary evidence on the right.
- Flipper of a whale and wing of a batHomologous structures
- Wing of a bird and wing of an insectAnalogous structures
- Pelvic girdle in pythonsVestigial organs
Answer
The correct pairings are: Flipper of a whale and wing of a bat matches Homologous structures; Wing of a bird and wing of an insect matches Analogous structures; Pelvic girdle in pythons matches Vestigial organs.
The flipper of a whale and wing of a bat are homologous structures because they share a common pentadactyl bone arrangement derived from a shared ancestor. The wing of a bird and wing of an insect are analogous structures because they evolved independently to perform the same function of flight. The pelvic girdle in pythons is a vestigial organ because it is a reduced structural remnant inherited from ancestral limbed reptiles.
