Question

List and briefly describe each of the 4 types of evidence that support evolution

Answer 1

Answer

• Anatomy Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
  
• Molecular biology DNA and the genetic code reflect the shared ancestry of life.
  
• Biogeography The global distribution of organisms and the unique features of island species reflect evolution and geological change.
  
• Fossils Fossils document the existence of now-extinct past species that are related to present-day species.
  
• Direct observation We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).
