Important Figures and Events in Biology - Chapter Summary
The lessons in this chapter focus on key events in the history of biology as well as the scientists who made these important contributions. You'll cover the nature of science and various biological theories. The lessons cover the following topics to help you gain an understanding of important figures and events in biology:
- Development of biological theories
- Key events in biological study
- Louis Pasteur and the germ theory of disease
- Development of cell theory
- Historical developments in heredity, evolution and ecology
- Structure and function of genetic material
The text and video lessons offer an effective and fun way to learn. View the lessons as often as you'd like. For video lessons, if you want to review only one or two main points, use the tags to jump to that part of the video. Take lesson quizzes to assess how well you've grasped the materials.
1. The Nature of Science
This lesson will explore the basic nature of science. It will distinguish science from pseudoscience and hypothesis from theory and natural law; it will give plenty of examples of each.
2. How Biological Theories Develop
The process of developing scientific theories is a crucial part of understanding the natural world. Here we will examine how biological theories develop. At the end, you can test your knowledge with a brief quiz.
3. Key Events in the History of Biological Study
The study of living things has a rich and exciting history. Here we will examine some of the key events in the history of biological study, their significance to the field, and the impacts of biological discoveries on humankind. At the end, you can test your knowledge with a brief quiz.
4. The Germ Theory of Disease: Definition & Louis Pasteur
In this lesson, we will look at one of the most influential experiments in the field of microbiology. We will learn how Louis Pasteur disproved the theory of spontaneous generation which helped lead to the development of the germ theory of disease.
5. The Development of Cell Theory
Cell theory is a fundamental theory in biology that makes generalizations about cells. In this lesson, you'll learn about the development of modern cell theory and the scientists behind it.
6. Developments in Heredity, Evolution & Ecology
Advancements in the fields of evolution, heredity, and ecology have been significant in the past couple of centuries. Here we will investigate the major developments in these fields, with emphasis on the more recent.
7. Genetic Material: Definition, Structure & Function
Genetic material, also known as deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA), plays a fundamental role in the composition of living organisms. Learn more about the definition, structure, and function, then test your understanding with a quiz.
