SET 5: Speciation,
Classification and Evolutionary Relationships
Introduction: This set
covers the formation of new species, evolutionary classification, the
Miller-Urey experiment, and how organisms are grouped based on evolutionary
relationships. It explores the evidence for evolution and mechanisms of
speciation.
