Ch 64: Genetics, Evolution & Environmental Influences on Behavior

About This Chapter

Watch our video lessons to learn all about genetics, evolution and environmental influences on behavior. Find out about the genetic code and learn about the evidence in favor of evolution.

Genetics, Evolution and Environmental Influences on Behavior - Chapter Summary

In this chapter, our instructors discuss the contributions of genetics, evolution and the environment on determining behavior. You'll learn about the genetic code and the processes of cell division, as well as the connection between genetics and human behavior.

You'll find out about the evidence supporting the theory of evolution: evidence from paleontology, biogeography, embryology, and other fields. As you progress through the chapter you can study biological abnormalities and biological treatments. After completing this chapter, you should be able to:

  • Describe how the genetic code can be influenced by mitosis and meiosis
  • Discuss how genetics contributes to our understanding of human behavior
  • Enumerate the evidence in favor of the theory of evolution
  • Identify sources of biological abnormalities
  • Discuss biological treatments used for psychological disorders
  • Assess the biological model

Our approach includes brief, engaging video lessons coupled with corresponding self-assessment quizzes. There are also transcripts to provide greater detail. We give you key terms to highlight the most important points you need to know. Visiting a segment of a video to review a concept is easy. Just use our convenient jump feature in the timeline to take you directly back to the spot you want to see. If you have questions about the materials, you can ask our instructors, who are subject matter experts in their fields.

The Genetic Code: Influence of Mitosis, Meiosis & Crossing Over

1. The Genetic Code: Influence of Mitosis, Meiosis & Crossing Over

In this lesson, we will learn what the genetic code is and how it can be affected by mitosis, meiosis and crossing over. When mistakes are made and genes are altered, it can have a negative impact on human development.

How Genetics Helps Us Understand Human Behavior

2. How Genetics Helps Us Understand Human Behavior

This lesson demonstrates how physical anthropologists use genetics to better understand the human experience. You'll learn how they combine their knowledge of both biology and the social sciences together to contribute to their field.

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

3. 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.

Sources of Biological Abnormalities: Genetics & Evolution

4. Sources of Biological Abnormalities: Genetics & Evolution

There are many factors that can affect a person's mental health. How do elements like genetics and evolution play a role in psychology? In this lesson, we'll look closer at how genetics and evolution can affect mental illness.

Biological Treatments for Psychological Abnormalities

5. Biological Treatments for Psychological Abnormalities

The biological model of psychology focuses on treating the underlying physical issues that might be causing psychological disorders. In this lesson, we'll go through some common biological treatments for mental illness.

Assessing the Biological Model: Strengths and Weaknesses

6. Assessing the Biological Model: Strengths and Weaknesses

What causes mental illness? Some psychologists believe that psychological disorders are caused by physical problems. In this lesson, we'll assess the strengths and limitations of the biological model of abnormality.
