A.

Fossils

Fossils provide the direct evidences of organic evolution. It may be entire organisms buried in sediment or snow or a small part or impressions of ancient organisms on leaf or stem.

Morphology is the study of form and structure in organisms. Study of homologous and analogous organs provide evidence of evolution.

Embryology provides evidence of organic evolution which is based on basic laws of principles of embryonic development.

Vestigial organs are degenerate, non- functional and rudimentary organs. These provide evidences for organic evolution.
