Explanation:
- <u>Anatomy.</u> Also known as Homology, is the study of homologous structures of species with similar physical features, as proof of direct descent and ancestry.
- <u>Molecular biology and Genetics</u>. DNA and the genetic code reflects the shared ancestry of life, indicative of how species are related.
- <u>Fossil Records.</u> Fossils register the existence of pre-existing species which are related to present-day species.
- <u>Biogeography</u>. The geographic distribution of organisms on Earth, as well as their distinct features is an indicator of evolution and geological change.
- <u>Direct observation. </u>Organisms with short lifespan can be observed as evolutionary cases.
