Vertebrates: Origin, Characteristics & Diversity

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.

Jawless Craniates: Class Myxini & Class Petromyzontida

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.

Fishes and Sharks: Origins of Jaws in Vertebrates

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.

Tetrapods: Development of Limbs in Vertebrates

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?

Amniotes: Definition and Evolutionary Characteristics

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.

Primates and Human Origin

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.

Coelom: Definition, Formation & Function

7. Coelom: Definition, Formation & Function

The coelom exists in multicellular organisms. As a feature of higher-classed organisms, it serves a very important purpose. In this lesson, we'll discuss the formation and use of the coelom in living organisms.

Marsupial: Definition, Facts & Examples

8. Marsupial: Definition, Facts & Examples

In this lesson you will learn about this fascinating category of animals including what defines a marsupial, examples of marsupials, how marsupials function, where they live and how they came to live in those places.
