Identify the image. How does this image provide evidence for evolution?

• Homologous structures show that even animals from different species have the same basic structure, suggesting they may share one common ancestor.

• Homologous structures show that animals for different species have a variety of different structures, suggesting that each has a different ancestor.

• Analogous structures show that bones length plays a vital role in the evolution of various species.

• Analogous structures show that the same basic bone structure may be used in a variety of different functions.
