Question

what is suggested by the anatomical similarity of different species of vertebrates?
recent common ancestry
no evolutionary relationships between the groups
evolution from a distant common ancestor
similar environments in the past

Explanation:

Anatomical similarities (like homologous structures shown in the image) among vertebrates indicate they share a distant common ancestor, as these traits are inherited through evolutionary descent rather than recent ancestry or similar environments alone.

Answer:

evolution from a distant common ancestor
