Biology 3.5 Describe processes and patterns of evolution

Key tips

  • When answering questions (especially resource-based questions), make sure your answers are specific instead of general. Refer to information given in the questions, and justify your comments.
  • The language for this subject is specific, so you must learn the relevant terms and definitions. Refer to the glossary in your text book or provided by your teacher.
  • Know the process of speciation well.
  • Be able to list and discuss all the agents that contribute to evolution (or changes in the gene pool). Make up your own mnemonic to remember these. Non-random mating, Natural selection, Mutation, Genetic drift (or use Bottleneck and Founder effect), Gene flow (or use Immigration and Emigration).
