What is the significance of identifying vestigial structures in the embryos of different animals?

• It demonstrates that embryos are fully developed at birth.

• It suggests that embryos of various animals share a common evolutionary history.

• It supports the idea that embryos of different species have identical structures.

• It proves that all embryos have the same function.

Which human anatomical structures are homologous to the wings of a bat, and what evidence supports this homology?

• Human arms because they both have the same structure.

• Human hair because they both have the same texture.

• 
  Human feet because they are both used for movement.

• 
  Human legs because they have the same bone features.
