About This Chapter
ASVAB: Evolution - Chapter Summary
If you're planning to take the Armed Services Vocational Aptitude Battery (ASVAB) you might need a refresher in evolution for the science sub-test. The following concepts are included in our fun video lessons:
- Adaptation, natural selection and the theory of evolution
- Random mutation and genetic variability
- The human fossil record
- Evidence for evolution
- Origins of the universe and life on Earth
Watch our lessons on any kind of device, day or night, as many times as you want. Refer to the print transcripts for review, and take the short quizzes that accompany each lesson to check your progress. By taking the multiple-choice test at chapter's end, you'll know if any additional study on evolution is needed.
ASVAB: Evolution Objectives
The military requires recruits to take this test to find out individuals' areas of strength and where their skills can best be put into play. The exam is a combination of multiple sub-tests, such as General Science. You may take the battery as a computer-assisted or pencil and paper test. The science sub-test checks for understanding of biological and physical sciences, of which evolution may be a part. Our multiple-choice assessments can help you rehearse for the same types of questions you might encounter on the ASVAB.
1. Theories of Evolution: Lamarck vs. Darwin
We'll look at the interplay between population genetics and environment. Are traits individually acquired or do entire populations evolve? The flying hamsters and a few other notable experiments will provide the answers.
2. Natural Selection & Adaptation: Definition, Theory & Examples
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. Natural Selection: Definition, Types & Examples
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. Genetic Variability and Random Mutation
Evolution is driven by variation among populations. The amount of variability determines how well a population can adapt to environmental changes, while random mutations can provide new variations that help a population adapt to unexpected changes.
5. The Human Fossil Record & Human Evolution
Fossils can help tell the story of how we evolved. This lesson sheds light on our closest relatives from the past and what traits human beings have developed over time. You'll learn about those species that are extinct but who live on in our genes.
6. Evidence for Evolution: Paleontology, Biogeography, Embryology, Comparative Anatomy & Molecular Biology
There is much support for the theory of evolution. This evidence comes from a variety of scientific fields and provides information that helps us trace changes in species over time. In this lesson, we'll look at this evidence and explore how it supports the theory of evolution.
7. Origins of the Universe: The Big Bang and Expanding & Contracting Universes
Students will learn the origins of the universe, the Big Bang theory, the timeline of the universe, how the universe is still expanding to this day, and what astronomers expect the universe to look like in the future.
8. 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.
9. 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.
10. 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.
11. The Evolution of Humans: Characteristics & Evolutionary History
Just like other organisms, humans have changed over time. We will look at the evolution of humans as well as connections with our primate relatives, including Old World and New World primates.
12. Coevolution: Examples & Definition
Can you imagine having a tongue three times the length of your body? There actually exists a moth with such a tongue, and it evolved due to the features of a flower that it feeds on. Learn about this and other examples of organisms that have evolved together.
