Pentadactyl plan of the fore limbs of frog, bird, horse, whale and man is a proof of?
Answer Details
The pentadactyl plan of the fore limbs of frog, bird, horse, whale, and man is a proof of evolution. The pentadactyl plan refers to the similar skeletal structure of the forelimbs of these organisms, which consists of five digits, or fingers, arranged in a similar pattern. This similarity in structure suggests that these organisms share a common ancestor and have evolved over time from a common ancestral form. This is consistent with the theory of evolution and not with spontaneous generation, locomotion, or creation.
