About This Chapter
Who's It For?
Anyone who needs help learning or mastering artificial and natural selection material will benefit from the lessons in this chapter. There is no faster or easier way to learn about artificial and natural selection. Among those who would benefit are:
- Students who have fallen behind in understanding the theories of Charles Darwin or the peppered moths
- 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 artificial and natural selection
- 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 Artificial and Natural Selection Theory of Evolution 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 Artificial and Natural Selection Theory of Evolution chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any artificial and natural selection question. They're here to help!
- Study With Flexibility: Watch videos on any web-ready device.
Students Will Review:
This chapter helps students review the concepts in an evolution unit of a standard biology course. Topics covered include:
- The work and voyages of Charles Darwin
- The processes of adaptation and natural selection
- Rapid adaptation
- Examples of artificial selection
- The differences between artificial and natural selection
1. Charles Darwin: Voyages, Theories & Works
In this lesson we explore the life and voyages of the 19th-century British naturalist Charles Darwin and his formulation of the theory of natural selection.
2. Natural Selection and Adaptation
How does natural selection help shape the amazing types of animals we witness around us? In this lesson, we'll explore adaptations and what they can tell us about a species' past evolution.
3. Types of Natural Selection
We'll take a look at the types of natural selection that can occur. From flying hamsters to moths, you'll start to grasp the different paths organisms can take as they respond to their changing environments over time.
4. An Example of Rapid Adaptation: The Peppered Moths
Normally, adaptations occur over thousands or millions of years. However, drastic changes in the environment can shorten the time period in which a change comes about. In such cases, we can learn a lot about the evolutionary process and how natural selection drives it forward.
5. Artificial Selection in Evolution
Humans have been selectively breeding for desirable traits in plants and animals for a long time. This artificial selection allows for a lot of control in the breeding process but can also lead to unintended mutations within a population of organisms.
6. Artificial Selection: Biology Lab
Natural selection is a major way that evolution works, but what happens when humans get involved? In this lesson, we'll see how humans influence the characteristics of a population through artificial selection.
