About This Chapter

Study the principles of evolution with this collection of informative and mobile-friendly anthropology lessons. These study resources can help you answer the evolution questions that could appear on the AQA A-Level Anthropology exam.

AQA A-Level Anthropology: Principles of Evolution - Chapter Summary

Study this series of anthropology lessons as you prepare for the AQA A-Level Anthropology exam. The chapter helps you define and understand important topics related to evolution, such as speciation, human origins, natural selection and more. These engaging and bite-sized lessons can help you with:

  • Summarizing the theory of evolution
  • Understanding the Hardy-Weinberg equilibrium equation and how it relates to different evolutionary agents
  • Defining speciation and recognzing the different types
  • Evaluating the concepts of natural selection, adaptation and genetic fitness
  • Recognizing the origins of humans
  • Assessing the significance of race from biological and sociocultural perspectives
  • Analyzing various body control and modification theories

We've designed these resources to help you study quickly and efficiently. You can be confident that you'll study the most important terms and concepts that may appear on the AQA exam. Each lesson comes with a short quiz to help you practice answering questions about evolution.

Theories of Evolution: Lamarck vs. Darwin

1. Theories of Evolution: Lamarck vs. Darwin

We'll look at the interplay between population genetics and environment. Are traits individually acquired or do entire populations evolve? The flying hamsters and a few other notable experiments will provide the answers.

Hardy-Weinberg Equilibrium I: Overview

2. Hardy-Weinberg Equilibrium I: Overview

In this lesson, we'll examine population genetics in greater detail. We'll also explore notions of Hardy-Weinberg equilibrium for large, stable populations. The Hardy-Weinberg equilibrium can serve as a reference point as we try to answer population genetics questions.

Hardy-Weinberg Equilibrium II: The Equation

3. Hardy-Weinberg Equilibrium II: The Equation

The Hardy-Weinberg equilibrium equation is represented by a polynomial, so we'll have to do some calculations. Don't be intimidated; a few coin tosses can help us make sense of allelic frequencies in a given gene pool.

Hardy-Weinberg Equilibrium III: Evolutionary Agents

4. Hardy-Weinberg Equilibrium III: Evolutionary Agents

In this lesson, you'll learn how the Hardy-Weinberg equation relates to different evolutionary agents and population changes. Discover how the equation may be used to discover populations that are not in equilibrium.

Natural Selection & Adaptation: Definition, Theory & Examples

5. Natural Selection & Adaptation: Definition, Theory & Examples

How does natural selection help shape the amazing types of animals we witness around us? In this lesson, we'll explore adaptations and what they can tell us about a species' past evolution.

Natural Selection: Definition, Types & Examples

6. Natural Selection: Definition, Types & Examples

We'll take a look at the types of natural selection that can occur. From flying hamsters to moths, you'll start to grasp the different paths organisms can take as they respond to their changing environments over time.

Genetic Fitness: Selection

7. Genetic Fitness: Selection

We have all heard the expression 'survival of the fittest.' Natural selection of organisms is based upon their fitness. But what exactly does 'fitness' entail? Here, we will explore how selection occurs at the physical and genetic levels.

Speciation: Allopatric and Sympatric Speciation

8. Speciation: Allopatric and Sympatric Speciation

Discover the definition of a species and learn more about how species split. Find out common terms related to the splitting of species and study what role polyploidy plays in the development of a species.

Prezygotic Reproductive Barriers & Speciation: Definition & Examples

9. Prezygotic Reproductive Barriers & Speciation: Definition & Examples

We may take for granted why animals choose to mate with other animals of similar appearance, but it's not that simple. There are actually biological barriers to reproduction that can prevent even seemingly closely related species from reproducing. This lesson looks at one such category of hindrances, prezygotic barriers, which make fertilization impossible.

Postzygotic Reproductive Barriers: Definition & Examples

10. Postzygotic Reproductive Barriers: Definition & Examples

Do flying hamsters represent a separate species from your run-of-the-mill hamsters? We'll get to the bottom of this by performing crosses between the two hamster types. You'll explore postzygotic reproductive barriers and their possibly tragic consequences.

Primates and Human Origin

11. Primates and Human Origin

You probably know that you are a primate, just like gorillas and monkeys. But you may be surprised to find out how long primates have been around and how many of them are still living on Earth, which are covered in this lesson.

Biological & Sociocultural Significance of Race

12. Biological & Sociocultural Significance of Race

The concept of race is powerful, troubling, encouraging, and confusing. In this lesson, we will talk about race in biological and sociocultural terms, and see how this has changed throughout history.

Controlling & Modifying the Body: Theories & Techniques

13. Controlling & Modifying the Body: Theories & Techniques

The human body is a powerful cultural tool. In this lesson, we are going to look at the role of the human body in transmitting and communicating culture and see what anthropologists say about this topic.
