Ahuman forearm, horse’s front leg, bat’s wing, and porpoise’s flipper have similar bone structure. what conclusions can we draw from the similarities in bone structure between these mammals?
1. since each limb is used for different functions, these species must be unrelated evolutionarily.
2. since each limb has a different shape, these species must be related evolutionarily.
3. since each limb shares the same type of bone structure but performs different functions, these structures are the product of adaptive evolution.
4. since each limb shares the same type of bone structure but performs different functions, these species cannot possibly be related evolutionarily.
