About This Chapter
OAE Biology: Theory of Evolution - Chapter Summary
Evolution is a multifaceted concept that might seem intimidating -- but not with our awesome, easy-to-use video study guide! Utilize it when you're preparing for the OAE Biology exam. In each lesson, we will introduce you to new terms and scientific laws and teach you how scientists discovered the phenomenon of evolution. After studying this guide, you'll be able to:
- Define evolution and cite evidence for it from fields like paleontology and biogeography
- Use the Hardy Weinberg Equilibrium to determine whether a genotype is evolving
- Understand natural selection and adaptation
- List the different types of natural selection
- Interpret fossil evidence for biological diversity, mass extinction, and speciation
- Track rates of evolution using punctuated equilibrium and the molecular clock hypothesis
Read the chapter transcripts as you follow along with these fun video lessons designed to make learning easier for you. Once you have a feel for the laws behind natural selection and speciation, head over to our self-assessments to see how you stack up against sample Biology OAE exam questions.
OAE Biology: Theory of Evolution Chapter Objectives
The Ohio Assessments for Educators (OAE) is the Ohio state licensure exam for new teachers and those whose licenses are set to expire. Those hoping to teach life sciences to 7th graders and older must score 220 on an adjusted range of 100-300 on the Biology OAE exam. Questions are based on a pre-established criterion decided on by the state of Ohio.
There are five domains in the Biology OAE. These video guides will prepare you to answer questions about the theory of evolution that will appear in the 'genetics and evolution' domain. This section counts for 27%, or about 40 questions, of the overall test. You will have three hours to complete the 150 stand-alone questions on the Biology OAE. Each question is multiple-choice and worth the same amount.
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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. Scientific Evidence That Supports Evolution
Evolution explains how species that are present on Earth today are modified descendants of their ancestors. This scientific theory is supported by many different types of evidence, which show how evolution is a very real and natural phenomenon.
9. Fossil Evidence for Biological Diversity, Speciation, & Mass Extinction
One of the best sources of evidence we have for evolution is the fossil record. Fossils provide a wealth of information on how species change over time and for exciting events like mass extinctions and new species formation.
10. Rates of Evolution: Punctuated Equilibrium & Molecular Clock Hypothesis
In general, evolution is a very long process. But rates of evolution can be different for different organisms. In this video lesson, you will identify how scientists study rates of evolution and fill in some of the missing 'steps' in the fossil record.
