About This Chapter
Taxonomy and Evolution - Chapter Summary
Evolutionary biologists understand how taxonomy has an impact on biological evolution. This chapter provides a thorough overview of how taxonomy is used to name and classify both extinct and living species. Students preparing for an exam or those who want to learn more about evolution will enjoy the informative lessons that comprise this chapter. Since the content can be accessed from any device, you'll be able to learn wherever you are. After studying the lessons in this chapter, you should be able to:
- Tell about the basics of taxonomy, which is the scientific naming of species
- Understand how cladograms and phylogenetic trees show the relationships between types of organisms
- Discuss ancient bacteria and true bacteria
- Demonstrate knowledge of a category of organisms called protists
- Compare and contrast plants and fungi
- Define the characteristics of animals, including vertebrates and invertebrates
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.
