Ch 9: MTTC Integrated Science (Elementary): Evolutionary Changes

About This Chapter

Evolution involves many changes on a varying number of levels within a life form. This set of lessons reviews the theory of evolution and its underlying concepts for the MTTC Integrated Science exam.

MTTC Integrated Science (Elementary): Evolutionary Changes - Chapter Summary

The theory of evolution branches into a library of information on the possibilities for changes on the genetic level. The video lessons in this chapter of the MTTC Integrated Science course prepares you with a thorough study of all of the information about evolution you have learned in the past, getting you ready to take the exam and become certified. This chapter includes the following topics:

  • The theory of evolution
  • Hardy Weinberg equilibrium
  • Forms of evolutionary change
  • Evidence of evolution in anatomy and biology
  • Types of natural selection and adaptation
  • Mutation and extinction
  • An introduction to speciation

The timeline below the video gives you a guided path through each lesson so that you can freely choose where you want to focus your attention without losing your place. If you have any areas that are giving you trouble and you wish to seek help, a panel of experts is available from your dashboard to answer any questions you may have about evolution.

MTTC Integrated Science (Elementary): Evolutionary Changes Objectives

In the state of Michigan, this exam is given to teachers of elementary school science that are seeking certification. The Life Science section of the exam contains questions about evolution, which will be given in multiple-choice format. This portion of the test accounts for twenty-five percent of all of its questions.

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. 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.

Evolutionary Change: Definition and Forms

5. Evolutionary Change: Definition and Forms

You've probably heard of Charles Darwin and evolution. We know that evolution is change over time, but here we will look at how these changes may have occurred during Earth's history.

Evidence for Evolution: Paleontology, Biogeography, Embryology, Comparative Anatomy & Molecular Biology

6. Evidence for Evolution: Paleontology, Biogeography, Embryology, Comparative Anatomy & Molecular Biology

There is much support for the theory of evolution. This evidence comes from a variety of scientific fields and provides information that helps us trace changes in species over time. In this lesson, we'll look at this evidence and explore how it supports the theory of evolution.

Natural Selection & Adaptation: Definition, Theory & Examples

7. 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

8. 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.

Speciation: Allopatric and Sympatric Speciation

9. 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

10. 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

11. 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.

Genetic Variability and Random Mutation

12. Genetic Variability and Random Mutation

Evolution is driven by variation among populations. The amount of variability determines how well a population can adapt to environmental changes, while random mutations can provide new variations that help a population adapt to unexpected changes.

Artificial Selection in Evolution

13. Artificial Selection in Evolution

Humans have been selectively breeding for desirable traits in plants and animals for a long time. This artificial selection allows for a lot of control in the breeding process but can also lead to unintended mutations within a population of organisms.

What Is Extinction? - Defining Background and Mass Extinction

14. What Is Extinction? - Defining Background and Mass Extinction

In this lesson you'll discover what the term 'extinction' means as well as learn the two different types of extinction: mass extinction and background extinction. You will also discover how humans contribute to extinction events.
