This is a lesson I used myself to teach the Evolution and Speciation concept of the Inheritance Genetics Inheritance and Populations unit, unit 7. - A level Biology, AQA specification.
Learning objective: To understand how genetic variation, environmental pressures, and population events interact to drive evolution and the formation of new species over time.
By the end of the lesson learners should be able to:
Success criteria:
SC1: Describe how genetic variation arises and how allele frequencies can change due to natural selection, genetic drift, and population events.
SC2: Explain how isolation (geographical or reproductive) leads to speciation and long-term evolutionary divergence.
SC3: Analyse data or models (e.g. simulations or selection graphs) to explain how selection pressures shape populations and biodiversity.
Contains past paper questions that target this topic, some questions require knowledge from prior lessons. The mark scheme is also included to verify answers.
Powerpoint contains 17 slides and 6 past paper questions.
