Theory of Evolution by Natural Selection

What is the relationship between evolution and biodiversity?

Inquiry Question

Overview

  • Explain biological diversity in terms of the Theory of Evolution by Natural Selection by examining the changes in and diversification of life since it first appeared on the Earth
  • Analyse how an accumulation of microevolutionary changes can drive evolutionary changes and speciation over time, for example:
    • Evolution of the horse
    • Evolution of the platypus
  • Explain, using examples, how Darwin and Wallace’s Theory of Evolution by Natural Selection accounts for:
    • Convergent evolution
    • Divergent evolution
  • Explain how punctuated equilibrium is different from the gradual process of natural selection
