Pentadactyl forelimb of vertebrate function due to differences in environment is
A
comparative anatomy
B
physiological evidence
C
embryological evidence
D
fossil records
Ask EduPadi AI for a detailed answer
Correct Option: B
The pentadactyl limb is a classic example used in comparative anatomy. Comparative anatomy studies similarities and differences in the anatomy of different species. The fact that the pentadactyl limb (five-fingered limb) is found across various vertebrates (e.g., humans, bats, whales) but with different functions (grasping, flying, swimming) is evidence of evolution from a common ancestor. The different functions are due to adaptations to different environments.
