The Evolution of Prokaryotes: Archaebacteria and Eubacteria

1. 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

2. 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

3. 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

4. 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
