The evidences that are used to study organic evolution in nature are basically grouped in three categories:

i. Morphological and anatomical evidences: These evidences include the study of homologous, analogous and vestigial organs to trace evolutionary relationships.

ii. Embryological evidences: These evidences include the study of development of embryo from an egg to an adult in different organisms (animal groups).

iii. Palaeontological evidences: These evidences deal with the study of fossil records to know about how far this evolutionary relationship goes.
