Background and context
Many different aspects of biology provide evidence for evolution:
Anatomy. Because this property was present in a common ancestor, species may have similar physical characteristics (homologous structures).
Molecular Biology is a branch of biology that deals with the study of The shared lineage of life is represented through genetic code and DNA. DNA comparisons can reveal how closely two species are related.
Biogeography. Evolution and geological change are reflected in the global distribution of fauna and the particular characteristics of island animals.
Fossils. Fossils provide evidence of the presence of now-extinct ancient species that are connected to current ones.
Direct observation. Small-scale evolution can be observed directly in species with short life cycles (for example, insecticide-resistant insects).
