The fact that diverse organisms such as humans, birds, and frogs share a general body plan suggests that they evolved from a common ancestor and form a coherent lineage.

Common descent is a fundamental principle of evolutionary biology, and it explains why organisms with different body plans can share similarities in their anatomy, physiology, and genetics.
