About This Chapter
Who's it for?
Anyone who needs help learning or mastering college biology material will benefit from taking this course. There is no faster or easier way to learn college biology. Among those who would benefit are:
- Students who have fallen behind in understanding the theories used to explain life on Earth
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning science (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about the origin and history of life on Earth
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources
How it works:
- Find videos in our course that cover what you need to learn or review.
- Press play and watch the video lesson.
- Refer to the video transcripts to reinforce your learning.
- Test your understanding of each lesson with short quizzes.
- Verify you're ready by completing the Origin and History of Life on Earth chapter exam.
Why it works:
- Study Efficiently: Skip what you know, review what you don't.
- Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
- Be Ready on Test Day: Use the Origin and History of Life on Earth chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any question on the origin and history of life on Earth. They're here to help!

In this chapter, you'll learn the answers to questions including?
- What theories are used to explain the origin of life on Earth?
- How are the major eras in Earth's history defined?
- How does endosymbiotic theory explain the evolution of cells?
- What forms of evolutionary change have occurred throughout Earth's history?
1. The Origin of Life on Earth: Theories and Explanations
Ever wonder how living things came from non-living things? We will explore what conditions on early Earth may have created life from non-living items.
2. The History of Life on Earth: Timeline and Characteristics of Major Eras
The Earth is over 4 billion years old. Ever wonder what happened during certain time periods in that large amount of time? We will look at the major eons and eras of Earth's history along with important characteristics of each.
3. 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.
4. Evolutionary Change: Definition and Forms
You've probably heard of Charles Darwin and evolution. We know that evolution is change over time, but here we will look at how these changes may have occurred during Earth's history.
