What best describes the hind leg bones seen in the whale?

• The bones are analogous structures to the fins of living fish.

• The bones are vestigial structures that had a function in an ancestor.

• The bones are homologous structures to the wings of butterflies.

• share a common population
• speciation

• Distantly related they are.

• It doesn't prove anything.

• They look alike.
