Ch 5: Evolution for Anthropologists: Help and Review

About This Chapter

The Evolution for Anthropologists chapter of this Intro to Anthropology Help and Review course is the simplest way to master an understanding of evolution in the context of anthropology. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of evolution as it relates to anthropology.

Who's it for?

Anyone who needs help learning or mastering introductory anthropology material will benefit from taking this course. There is no faster or easier way to learn introductory anthropology. Among those who would benefit are:

  • Students who have fallen behind in understanding evolution and population genetics
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning social science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about evolution for anthropologists
  • Students who struggle to understand their teachers
  • Students who attend schools without extra social science learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the Evolution for Anthropologists chapter exam.

Why it works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the Evolution for Anthropologists chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any evolution question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students will review:

This chapter helps students review the concepts in an evolution unit of a standard introductory anthropology course. Topics covered include:

  • Theory of evolution
  • Hardy Weinberg equilibrium
  • Effects of inbreeding
  • Adaptation and natural selection
  • Genetic fitness

13 Lessons in Chapter 5: Evolution for Anthropologists: Help and Review
Theory of Evolution

1. Theory of Evolution

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. Is the genetic makeup of our flying hamster population changing? 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.

Inbreeding: Definition and Effects

5. Inbreeding: Definition and Effects

You know you're not supposed to marry your sister or even your cousin. But why? In this lesson, learn why inbreeding can be harmful, but on the other hand, why it's sometimes done on purpose.

How to Calculate the Coefficient of Inbreeding

6. How to Calculate the Coefficient of Inbreeding

So, you know what inbreeding is and what effects it can have on a population. In this lesson, we'll walk you through the next step: how to calculate just how inbred an individual is.

Natural Selection and Adaptation

7. Natural Selection and Adaptation

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.

Types of Natural Selection

8. Types of Natural Selection

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

9. 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 I: Allopatric and Sympatric Speciation

10. Speciation I: 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.

Speciation II: Prezygotic Barriers

11. Speciation II: Prezygotic Barriers

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.

Speciation III: Postzygotic Barriers

12. Speciation III: Postzygotic Barriers

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.

Social Darwinism: Definition & Meaning

13. Social Darwinism: Definition & Meaning

Social Darwinism got its name due to the similar foundation it has to Charles Darwin's concepts of natural selection and the survival of the fittest. Darwin used these concepts to explain evolution. Learn about how these concepts are applied socially.
