Evidence of Evolution
Comparative Anatomy
Comparative anatomy can serve as the first line of reasoning in determining the relatedness of species.
Evidence
There are fossil records that show change of the anatomy of certain living organisms. organism with a similar structure must had acquired their ancestor traits from a conman ancestor.
Embryonic development
Embryonic Development (embryogenesis) is the series of changes an embryo undergoes, prenatal development, as it grows toward a mature organism.
Evidence
Scientists have looked at embryos from different animals and have found that they share many similarities. These similarities are evidence of a shared ancestor and evolution from that ancestor.
Biogeography

Vestigial structures
Vestigial Structres are a structure in an organism that has lost all or most of its original function in the course of evolution, such as human appendixes.
Evidence
Vestigial structures are often homologous to structures that are functioning normally in other species. Therefore, vestigial structures can be considered evidence for evolution.
Molecular biology
Molecular biology is the study of biology at a molecular level, for example proteins and acids, that are essential to life.
Evidence
These conserved molecules have changes, very slight changes, which occur over time. These are often referred to as molecular clocks and these are what have helped to support Darwin's theory of evolution.
Fossil Record
Fossils provide a unique view into the history of life by showing the forms and features of life in the past. Fossils tell us how species have changed across long periods of the Earth’s history.
Evidence
If you look at the fossil record, you find a succession of organisms that suggest a history of incremental development from one species to another. You see very simple organisms at first and then new, more complex organisms appearing over time.
