What is the term used for the process of descent with modification?

Convergent evolution is the evolution of similar features in distantly related groups because they have a common ancestor.

Analogous traits arise when groups independently adapt to similar environments in different ways.

Convergent evolution can result in the evolution of analogous traits.

The fossil record provides evidence of species extinction, but not the origin of new groups.

Fossils can document important transitions, such as the transition from sea to land in the ancestors of cetaceans.

The fossil record only provides evidence of species extinction, not changes within groups over time.

Convergent evolution is the evolution of similar features in closely related groups.

Analogous traits arise when groups independently adapt to different environments in similar ways.

The fossil record can document the transition from land to sea in the ancestors of cetaceans.

Convergent evolution occurs when closely related groups independently evolve similar features due to similar environmental pressures.
