what are the evidences of Evolution
Fossil Record
Comparative Anatomy
Embryology
Molecular Evidences
vital understanding relationships among creatures
Comparative Anatomy
remnants of an creature from the primitive times
Fossil Record
provides clues to its evolutionary past
Embryology
same structure, diff function
Homologous Structure
same function, diff structure
Analogous Structure
