Fossil Records
Pertains to Homologous and Analogous Structures
Comparative Sequence
Having similar structure and anatomical position in different organisms suggesting a common ancestor
Homologous Structures
Structures having a similar appearance, but not coming from a common ancestor
Analogous Structures
A structure found during the development stage of the embryo
Embryological Structures
The arrangement of amino acids in a protein
