NES General Science: Evolution - Chapter Summary
This comprehensive overview of evolution can ensure you have the knowledge needed to answer related questions on the NES General Science assessment. Upon completion of this chapter, you will be ready to:
- Explain theories related to the origin of life on Earth
- Identify the major eras and characteristics of Earth's history
- Define the concept of evolutionary change
- Recognize scientific evidence that supports evolutionary theory
- Describe the concept of extinction
- Explore mass extinction
The videos average about 10 minutes apiece, giving you access to short yet detailed lessons that help you condense years of subject matter as you study for the exam. Watch the videos in any sequence and as often as necessary until you're confident you comprehend the materials. The included lesson quizzes are also helpful for knowledge reinforcement as you prepare for the NES General Science exam.
1. The Origin of Life on Earth: Theories and Explanations
Scientific theories of the origin of life on Earth are varied and typically focused on the utilization of radiation and chemical compounds within the atmosphere of the planet. Learn about the early stages of life on Earth from a scientific perspective, and discover the explanations provided by the Oparin Hypothesis and the Miller-Urey experiment.
2. The History of Life on Earth: Timeline and Characteristics of Major Eras
Life on Earth started millions of years ago and these periods are classified into several major eras defined by the characteristics of the organisms existing within the appropriate timelines. Learn about the characteristics of different organisms that existed during major timelines in history.
3. Evolutionary Change: Definition and Forms
Evolution is a phenomenon that happens when organic matter changes over time to adapt and survive to its changing environment. Learn the definition and forms of evolution and discover how it is portrayed in organic matter.
4. Scientific Evidence That Supports Evolution
Evolution is a theory that describes how organisms change and adapt over the generations. Explore the scientific evidence that supports evolution, then discover its impact on biogeography, comparative anatomy, and molecular biology.
5. What Is Extinction? - Defining Background and Mass Extinction
Learn about extinction, which occurs when an organism ceases to exist anywhere on Earth. Learn the definition and background of extinction, explore mass extinction, and discover humanity's role in extinction rates.
