About This Chapter
FTCE Biology: Origins of Life on Earth & Taxonomy - Chapter Summary
The lessons in this chapter are designed by our expert instructors to aid you in your study for the FTCE Biology exam. Review text and video lessons on endosymbiosis theory and patterns of evolutionary change and study uses for the dichotomous key. Once you complete this chapter you should be able to:
- Understand the origins and history of life on Earth
- Identify the evolutionary timeline of early hominids
- Explain the classification systems of classical taxonomy, phenetics and cladistics
- Discuss the taxonomy system of classifying and naming living things
- Define the dichotomous key classifying tool
Our instructors present each lesson in an easy to understand format that allows you to study at your own pace and on your own time. Choose from text or video lessons, and then utilize the quizzes to make sure you understand the material before taking the FTCE Biology test. And follow your progress in your personalized dashboard.
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.
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.
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.
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.
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.
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.
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.
