About This Chapter
Who's it for?
Anyone who needs help learning or mastering high school biology material will benefit from taking this course. There is no faster or easier way to learn biology. Among those who would benefit are:
- Students who have fallen behind in understanding the origins, diversity and features of vertebrates
- 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 vertebrates
- 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 vertebrate 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 vertebrate chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any vertebrate 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 a vertebrate unit of a standard high school biology course. Topics covered include:
- Fishes and sharks
- Jawless craniates
1. 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.
2. 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.
3. 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.
4. 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?
5. 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.
6. 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.
7. Gastrulation in Frogs: Definition & Concept
Many animals develop very similarly. If you were to look at how many seemingly unrelated organisms develop, you would find that the first basic steps of life are very close and almost exactly the same. We will look at gastrulation here.
8. Primates: Definition, Evolution & Characteristics
Primates, including apes, monkeys and prosimians, make up our extended family tree. New and exciting fossils have expanded our understanding of this peculiar group to which we belong. Learn more about our closest cousins in the animal kingdom.
9. What is an Amphibian? - Definition & Characteristics
An amphibian is a class of animals that live their lives both in and out of water. There are three orders within this class, the most common of which includes frogs and toads. Learn more about these animals, and take a short quiz at the end.
