Whales, bony fishes, and cartilaginous fishes all have similar adaptations that enable them to live in the ocean. Figure 1 shows the phylogenetic relationships of selected vertebrates.
Based on the phylogenetic relationships shown in Figure 1, which of the following best explains the similarities exhibited by whales, bony fishes, and cartilaginous fishes?
Convergent evolution, because these organisms do not share a recent common ancestor.
Adaptive radiation, because all three groups evolved from a unique, shared common ancestor from the cartilaginous fishes group.
Mutation, because the shared traits can be traced back to a shared tecent common ancestor
Founder effect, because all three groups formerly existed together as one population that then wan disrupted, causing speciation
