About This Chapter
Phylogeny - Chapter Summary
Phylogeny is a hypothesis as a result of the study of evolutionary relationships among organisms, meaning that we can classify organisms by looking at their evolutionary history. In this chapter, our instructors explain the various ways biologists classify living things. You'll learn about the evolution of bacteria, protists, plants, fungi, animals, and humans. Our expert instructions have created these lessons to help you prepare for the exam. We've divided this chapter into smaller lessons, so you can learn about these concepts one video at a time. Utilize the quizzes to check your progress.
After completing this chapter, you should be able to answer exam questions pertaining to:
- Understanding cladograms and phylogenetic trees
- Explaining the evolution of prokaryotes
- Exploring the evolution of protists
- Summarizing the evolution of plants and fungi
1. 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.
2. 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.
3. 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.
4. 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.
