9 Lessons in Chapter 22: Phylogeny and the Classification of Organisms: Homework Help
Taxonomy: Classification and Naming of Living Things

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.

Cladograms and Phylogenetic Trees: Evolution Classifications

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.

The Evolution of Prokaryotes: Archaebacteria and Eubacteria

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.

The Evolution of Protists: Importance & Evolutionary History

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.

The Evolution of Plants and Fungi: Characteristics & Evolutionary History

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.

The Evolution of Animals: Importance & Evolutionary History

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.

The Evolution of Humans: Characteristics & Evolutionary History

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.

Carolus Linnaeus: Classification, Taxonomy & Contributions to Biology

8. Carolus Linnaeus: Classification, Taxonomy & Contributions to Biology

There are millions of species on Earth. How can we name and organize all of them without getting confused? We use a system developed in the 1700s by Carolus Linnaeus. Learn more about him and his contributions in this lesson.

Clade: Definition & Overview

9. Clade: Definition & Overview

In order to organize and categorize things in science, we have to create graphs, charts, tables, etc. A clade is just a type of organizational method found within these graphs and charts. We will discuss a clade here and then test your knowledge with a quiz.
