Ch 11: Intro to Biodiversity & Change

About This Chapter

Use these lessons to familiarize yourself with biological change and biodiversity. Gain insight into the theory of evolution by studying concepts such as natural selection and adaptation.

Intro to Biodiversity & Change - Chapter Summary

Our professional instructors explain the theory of evolution and provide evidence in all areas of scientific study - from the molecular to the paleontological. As you progress through the chapter, you'll learn about processes that are a part of evolution, as well as how to organize and classify all living things. By the end of these lessons, you should be able to:

  • Discuss the theory of and evidence for evolution
  • Identify natural and artificial selection
  • Define adaptation
  • Use and explain taxonomy, phenetics, and cladistics

These short, engaging lessons are designed by professional instructors to make the learning process quick and easy. Each lesson focuses on a different key topic, allowing you to ensure your understanding of one subject before moving to the next. You can gauge your understanding of the topics in this chapter with the interactive self-assessment quizzes.

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.

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

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.

Natural Selection & Adaptation: Definition, Theory & Examples

3. 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.

Artificial Selection in Evolution

4. 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.

Taxonomy: Classification and Naming of Living Things

5. Taxonomy: Classification and Naming of Living Things

The name you give to a living thing may be completely different than the name someone else uses. In science, we use a common naming system for all living things to avoid confusion. This lesson will explore the basics of our classification system.

Classification Systems: Classical Taxonomy, Phenetics & Cladistics

6. Classification Systems: Classical Taxonomy, Phenetics & Cladistics

How do we begin to sort out the millions of species on Earth? In this lesson, we will explore three of the most common classification systems used by modern science. Then, you will be able to test your understanding with a brief quiz.
