- The Fossil Evidence
Learn how different fields of biology provide evidence for evolution on macro and micro scales. See examples of homologous and analogous features, DNA comparisons, fossil records, and direct observation of evolution.
Molecular similarities provide evidence for the shared ancestry of life. DNA sequence comparisons can show how different species are related. Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved.
