About This Chapter
Evidence Supporting Evolution - Chapter Summary
This chapter provides scientific data that supports the theory of evolution. You'll learn about modern-day species that have evolved from their ancestors and how the phenomenon of evolution plays out in today's world. You'll also discover how the fossils of prehistoric plants and animals provide scientists with information about the past.
Using these video lessons, you'll learn more about mass extinction and how humans are creating extinction scenarios in today's world. You'll also learn about antibiotic-resistant bacteria and what they tell scientists about evolution. As you complete each lesson, you'll learn more about:
- How fossils are formed
- Ways scientists learn about the history of the earth
- What causes species extinction
- Ways antibiotic-resistant bacteria have evolved
- How MRSA and other pathogens threaten human life today
Our videos are designed by professional instructors to ensure that learning is interesting and easy. If you need to review a section of one of video lessons, simply use the video tabs in the Timeline to navigate to the part of the video you want to watch. After you've reviewed a lesson, take the corresponding quiz to test yourself on how well you understood the information.
1. Scientific Evidence That Supports Evolution
Evolution explains how species that are present on Earth today are modified descendants of their ancestors. This scientific theory is supported by many different types of evidence, which show how evolution is a very real and natural phenomenon.
2. Fossil: Definition, Types, Characteristics & Examples
Fossils provide scientists with many clues about Earth's history, offering evidence of dinosaurs and strange plants that existed in the past. This lesson will define a fossil, look at different types and characteristics of fossils, and then describe how fossils are formed.
3. Fossil Record: Definition & Examples
This lesson teaches you about the fossil record. It explains how scientists learn about Earth's distant past and highlights what fossils can tell scientists about ourselves and other organisms.
4. The Causes of Species Extinction
What do dinosaurs, passenger pigeons, and a species of Australian rat all have in common? They have all gone extinct. This lesson will examine the causes of species extinction from mass extinctions in the past to human-caused extinctions today.
5. Antibiotic Resistant Bacteria: Evolution & Examples
Learn about antibiotic resistant bacteria and how they evolved. We will look at some examples of antibiotic resistant bacteria that currently exist. A short quiz will follow in order for you to test your knowledge.
6. MRSA and Multi-Drug Resistant Pathogens
We've learned a lot about different kinds of antibiotics and how they work. But there are some pathogens that virtually no antibiotics work against. In this lesson, we learn about two of these pathogens, and how they threaten to take us back to a pre-antibiotic era.
