This is the study of embryos and their development.

• Embryology
• Evolution
• Embryos
• adaptation

This kind of structure is when the bones have similar form but are used for different functions.

• analogous structure
• homologous structure
• vestigial structure

This kind of structure is when the structures have the same function but have a different structure/form. 

• analogous structure
• homologous structure
• vestigial structure

This kind of structure are body parts that have no function now and are just the remains from an ancestor.

• analogous structure
• homologous structure
• vestigial structure

This is any alteration in a structure of a function that allows an organism to be better suited for its environment.
