Explain how the adaptations of the pentadactyl limbs are adapted for swimming in whales, running in lizards and grasping in frogs and humans

This is an example of homologous structures.

Each of these limbs has adapted to enable organisms to survive in their environment.

All these animals have similar embryonic tissues, meaning they looked very similar as an embryo.

Homologous structures provide evidence that these animals all came from a common ancestor.
