About This Chapter
Phylogeny and the Classification of Organisms - Chapter Summary and Learning Objectives
Evolution is the process of one specimen changing into another form over time. This concept is often related to how life on earth began and how humans developed. Usually the evolutionary process takes hundreds of years. Scientists speculate that every living thing has gone through evolution, including plants, animals, and humans. In this chapter, you'll get to take a look at the different evolutionary histories of various species. You'll have a chance to learn how characteristics of a being can help scientists to understand its evolutionary process. Some of the things that will be covered in the lessons in this chapter include:
- Evolution classifications
- The importance of prokaryotes
- The importance of protists
- How plants and fungi evolved
- The importance of animal evolution
- Evolution in humans
|Ladograms and Phylogenic Trees: Evolution Classifications||Discover the way relationships in evolution are illustrated.|

|The Evolution of Protists: Importance & Evolutionary History||Explore the evolutionary history of protists.|
|The Evolution of Plants and Fungi: Characteristics & Evolutionary History||Analyze the evolution of plants and fungi.|
|The Evolution of Animals: Importance & Evolutionary History||Study how animals evolved.|
|The Evolution of Humans: Characteristics & Evolutionary History||Learn about the evolutionary characteristics and history of humans.|
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.
