Unit 7 (part I) We will cover sections 7.1 to 7.7. Like unit 6, unit 7's sessions are 90 minutes long because unit 7 is quite long. We will discuss Darwin's theory of natural selection and compare it to artificial selection. Then, we will discuss population genetics, with an emphasis on the founder and bottleneck effects. We will discuss Hardy-Weinberg equilibrium, what conditions are required for it, and how to solve mathematical AP questions about it. We will discuss the evidence supporting evolution and common ancestry. As always, I will take questions anytime during the session, and we will solve some related AP-style questions at the end of the session.

During this session, we will cover the second part of Unit 7 Natural Selection, which will include the following topics: 7.8 Continuing Evolution, 7.9 Phylogeny, 7.10 Speciation, 7.11 Extinction, 7.12 Variations in Population, and 7.13 Origin of Life on Earth. The session will include both an explanation/review of the aforementioned topics and practice questions on them.

Unit 7 (part II) We will cover sections 7.8 to 7.13. This session is 90 minutes long because we have a lot to cover! In this session, we will talk about how evolution is a continuous process and look at evidence that illustrates that. We will also discuss phylogeny and how to draw and interpret cladograms and phylogenetic trees. We will revise the biological species concept and how speciation occurs (allopatric and sympatric speciation, prezygotic and postzygotic barriers) and go over the causes and effects of extinction and briefly explain the five mass extinctions that have occurred on our planet. Finally, we will discuss variations in populations and the hypotheses about the origin of life. I will answer any questions, and we will solve practice questions.

Unit 8 (part I) We will cover sections 8.1 to 8.4. We will start our ecology unit by discussing how different organisms communicate and respond to their environments. We will also discuss the different types of organisms based on how they regulate body temperature (endotherms and ectotherms), the source of their energy, and their trophic levels. We will also discuss density-dependent and density-independent factors and mathematical equations related to this concept. We will solve AP-style practice questions on the concepts we discuss.
