About This Chapter
Classification of Organisms Overview - Chapter Summary
For an overview of organism classification and naming concepts, take a look at this convenient online biology chapter. Though a collection of bite-sized lessons, you'll review the study of taxonomy, as well as the evolution of different types of organisms throughout history. By the end of the chapter, you should be able to:
- Define taxonomy and the classification/naming of living things
- Interpret cladograms and phylogenetic trees
- Explain how prokaryotes and protists evolved
- Evaluate the characteristics and evolutionary history of plants and fungi
- Discuss the evolutionary history of animals and humans
Accompanying each lesson is a short quiz that's designed to solidify your comprehension of key taxonomy terms and evolutionary concepts. You can work through the chapter at any time that fits your schedule, and it's accessible on a computer or mobile device. Finally, if you have questions about the material, you can reach out to our subject-matter experts with our easy-to-use Ask the Expert feature.
1. 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.
2. Cladograms and Phylogenetic Trees: Evolution Classifications
Family trees help show how people are related to each other. Similarly, scientists use cladograms and phylogenetic trees to study the relationships between organisms.
3. The Evolution of Prokaryotes: Archaebacteria and Eubacteria
The first living organisms on Earth were bacteria. These small organisms still exist today and are responsible for many things. In this lesson, we will explore both ancient bacteria and true bacteria.
4. The Evolution of Protists: Importance & Evolutionary History
Some organisms are very familiar. However, there are some that play vital roles in our lives that we don't even think about. We will look at a group of one of these unfamiliar kingdoms - protists.
5. The Evolution of Plants and Fungi: Characteristics & Evolutionary History
In early classification systems, plants and fungi were grouped together. While there are some similarities between these two kingdoms, there are some key differences that we will explore.
6. The Evolution of Animals: Importance & Evolutionary History
The animal kingdom ranges from simple organisms like sponges to complex organisms like humans. We will look at some defining characteristics of animals as well as examples of both invertebrates and vertebrates.
7. 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.
