About This Chapter
Organic Evolution - Chapter Summary
Get to work studying this chapter and get reacquainted with the topic of organic evolution. Our instructors use each lesson to teach you about a different aspect of evolution, including such concepts as population genetics, the theories of Mendel and Darwin, changes over time, and gene flow. As there are many topics within this chapter, the instructors have divided the chapter into individual lessons, allowing you to focus on each topic. After you make your way through all of the lessons, you will be ready to:
- Describe theories related to evolution
- Analyze molecular biology
- Examine the Hardy Weinberg Equilibrium equation
- Compare types of natural selection
- Explain the three main causes of microevolution
- Point out the types and sources of genetic variation and examples of adaptive radiation
- Determine the significance of sympatric and allopatric speciation
- Establish the different kinds of reproductive isolation
Before an major exam, you will want to practice answering questions, and we provide you that practice through the use of our self-assessment quizzes. Our quizzes use the same form of multiple-choice style questions found on most exams. The quizzes will help you evaluate your knowledge concerning such things as definitions, terminology, concept application, problem-solving, and more.
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. Modern Evolutionary Synthesis: Definition & Formation
In this lesson, we will discuss the history of evolutionary theory. We will focus on Darwin and Mendel, discussing why some scientists initially believed these two revolutionaries were incompatible, and how these problems were resolved.
4. Hardy-Weinberg Equilibrium: Definition, Equation & Evolutionary Agents
In this lesson we will define Hardy-Weinberg equilibrium and break down the Hardy-Weinberg equation to figure out if a population of hypothetical beetles is evolving.
5. 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.
6. Causes of Microevolution: Natural Selection, Gene Flow & Genetic Drift
Environments are dynamic, which causes populations to be as well. In this lesson, you'll learn about microevolution, as well as the mechanisms behind it that cause changes in allele frequencies within populations.
7. What Is Genetic Variation? - Sources, Definition & Types
Natural selection is the process that drives evolution, but what drives natural selection? Genetic variation increases the genetic diversity in and among populations, allowing for new traits to become more or less prominent in the gene pool.
8. Adaptive Radiation: Definition & Example
Adaptive radiation is when members of a single group or lineage evolutionarily diverge into a variety of different forms. These forms are dictated by selection pressures and the use of habitats or resources.
9. The Evolution of Humans: Characteristics & Evolutionary History
Just like other organisms, humans have changed over time. We will look at the evolution of humans as well as connections with our primate relatives, including Old World and New World primates.
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. Reproductive Isolation: Definition, Types & Examples
Typically, animals can only mate within their own species. In this lesson, you will learn about reproductive isolation, or when two species are unable to reproduce, including types and examples of isolation.
