Anatomical structures that serve no apparent function. Ex. the appendix in humans.

• Functional structures
• Obsolete organs
• Useful appendages
• Vestigial structures

These anatomical structures have a similar function, but the two species do NOT share a common ancestry.

• vestigial structures
• homologous structures
• analogous structures
• anatomical structures

Anatomy of embryos are compared from different species through the embryos development, this can support common ancestry.
