Life on Earth: Origin & History

1. Life on Earth: Origin & History

How did life on Earth begin? How did we get from those primitive beginnings to the vast diversity we see today? In this lesson we'll cover both the origin and history of life on Earth, taking you on an exciting adventure through time.

The Endosymbiosis Theory: Evolution of Cells

2. The Endosymbiosis Theory: Evolution of Cells

Ever wonder why some cells are very simple and others are complex with countless organelles to remember? We will look at how simple cells evolved to become more complex cells - as well as evidence to support this.

Forms & Patterns of Evolutionary Change

3. Forms & Patterns of Evolutionary Change

Since Charles Darwin introduced natural selection, scientists have come up with different ideas on how evolution proceeds, and how living things evolve over time. This lesson will focus on different patterns of evolution.

Early Hominids: Evolution & Timeline

4. Early Hominids: Evolution & Timeline

In this lesson we explore early hominids: humanity's earliest ancestors. By examining some of these species we can learn the important aspects that fostered human evolution and just some of the difficulties that face modern paleoanthropologists.

Classification Systems: Classical Taxonomy, Phenetics & Cladistics

5. Classification Systems: Classical Taxonomy, Phenetics & Cladistics

How do we begin to sort out the millions of species on Earth? In this lesson, we will explore three of the most common classification systems used by modern science. Then, you will be able to test your understanding with a brief quiz.

Taxonomy: Classification and Naming of Living Things

6. 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.

The Dichotomous Key: A Classifying Tool

7. The Dichotomous Key: A Classifying Tool

Sometimes, the best way to identify an object is to take a step-by-step approach. Dichotomous keys are perfect for this, helping us classify unknown objects through a series of questions and answers that lead us down the correct path.
