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.

Mammals: Traits, Behavior & Grouping

6. Mammals: Traits, Behavior & Grouping

Ever wondered what the largest mammal on Earth was? Or what traits connect mammals together? In this lesson, you will discover the basic traits of mammals, some of their behavior, and how they are grouped by scientists. Read on!

The Human Fossil Record & Human Evolution

7. 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.

The Evolution of Humans: Characteristics & Evolutionary History

8. 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.
