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
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.
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.
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.
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.
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.
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.
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.
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.
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.
10. 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.
11. Speciation: 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.
12. Speciation: 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.
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.
