Check out the Animal Biology chapter's fun video lessons and clear text discussions as you prepare for an ASVAB subtest. The chapter also features practice quizzes that you can take to help determine your understanding of the material.

ASVAB: Animal Biology - Chapter Summary

The Animal Biology chapter will give you a good grasp of a variety of issues concerning different animal groups, including origins and key characteristics. The text lessons throughout this ASVAB prep chapter contain key terms in bold print that deal with:

  • Humans and primates
  • The evolution and diversity of vertebrates
  • Tetrapods and the development of vertebrate limbs
  • What amniotes are and different types
  • Protostomes and deuterostomes
  • Types of jawless craniates
  • The origins of jaws in vertebrates
  • The Parazoa and Radiata animal groups

Watch the video lessons for a fun and efficient way to become familiar with the material in this chapter. You can easily go back to any video lesson segment that you want to review further by using the handy video tags.

Objectives of the ASVAB: Animal Biology Chapter

Performance on the ASVAB indicates the examinee's fit for joining the military and also serves to designate a suitable function. The General Science subtest on the ASVAB is the area of the exam that's targeted by this chapter. Any questions concerned with the Animal Biology chapter's content are going to be among that subtest's total of 25 questions on the paper exam and 16 questions on the computer-based one.

The Evolution of Animals: Importance & Evolutionary History

1. The Evolution of Animals: Importance & Evolutionary History

The animal kingdom ranges from simple organisms like sponges to complex organisms like humans. We will look at some defining characteristics of animals as well as examples of both invertebrates and vertebrates.

Parazoa: Definition and Characteristics

2. Parazoa: Definition and Characteristics

The sub-kingdom Parazoa is a special group of animals that are unlike any other. In this video lesson, you'll learn about the characteristics of Parazoans and identify what makes them a unique section of the Animal Kingdom.

Radiata: Definition and Characteristics

3. Radiata: Definition and Characteristics

The super-phylum Radiata describes a unique and interesting group of animals. In this video lesson you'll identify various animals that belong in this classification as well as describe the characteristics that make them so identifiable.

Protostomes: Definition and Characteristics

4. Protostomes: Definition and Characteristics

Though you may not be able to tell just by looking at them, protostomes are an evolutionarily related group based on shared characteristics of their body plans. In this lesson, you will identify these characteristics, as well as see examples of the variety of animals this group encompasses.

Deuterostomes: Definition and Characteristics

5. Deuterostomes: Definition and Characteristics

Deuterostomes, like tunicates and urchins, are amazing creatures that are classified together because they share aspects of their evolutionary pasts. In this lesson, you'll identify these characteristics and see what makes this group of animals unique.

Vertebrates: Origin, Characteristics & Diversity

6. Vertebrates: Origin, Characteristics & Diversity

Vertebrates are diverse and widespread across Earth, but this was not always the case. In this lesson you'll learn about the origins and evolution of these animals, as well as explore their vast diversity.

Jawless Craniates: Class Myxini & Class Petromyzontida

7. Jawless Craniates: Class Myxini & Class Petromyzontida

The word 'fish' brings specific images to mind. But before these fish existed, there were the jawless craniates. In this lesson you will identify two classes that fall into this category: the hagfishes and the lampreys.

Fishes and Sharks: Origins of Jaws in Vertebrates

8. Fishes and Sharks: Origins of Jaws in Vertebrates

While it may appear to be a minor feature, the hinged jaw led to major changes in the evolution of animals. In this lesson, you'll discover some of the earliest jawed animals, the sharks and fishes of the world.

Tetrapods: Development of Limbs in Vertebrates

9. Tetrapods: Development of Limbs in Vertebrates

Having four limbs allowed for an incredible amount of diversification in the animal kingdom. But where did those limbs come from, and what types of diversifications arose from animals moving onto land?

Amniotes: Definition and Evolutionary Characteristics

10. Amniotes: Definition and Evolutionary Characteristics

One of the more 'recent' evolutionary developments in vertebrates is a terrestrial egg. This adaptation allowed for even greater diversity in this branch of the Animal Kingdom, giving rise to organisms that could now live their entire lives on land.

Primates and Human Origin

11. Primates and Human Origin

You probably know that you are a primate, just like gorillas and monkeys. But you may be surprised to find out how long primates have been around and how many of them are still living on Earth, which are covered in this lesson.
