About This Chapter

Use the lessons in this chapter for a comprehensive overview of the origins of life on Earth. Take a look at evidence used to support the theory of evolution.

Evidence for the Origin of Life - Chapter Summary

In this chapter, delve into the origins of life on Earth and learn about evolution, speciation and biodiversity. Specifically, you'll explore:

  • Origin of life theories
  • Fossil evidence supporting speciation, extinction and biodiversity
  • Classification
  • Cladograms and phylogenetic trees
  • Evidence supporting evolution

The lessons in this chapter have been designed to provide you with various methods for understanding and memorizing the information. Some lessons contain short videos to demonstrate the material. The video's transcript is included as a text-based resource. You can take a self-assessment quiz at the end of each text or video lesson to test your knowledge.

What is Geology? - Definition, History, Facts & Topics

1. What is Geology? - Definition, History, Facts & Topics

Did you know Earth is over 4.5 billion years old? Did you also know that the continents move and have joined together to create supercontinents? Learn about geology, what it is, its history and some interesting facts.

The Origin of Life on Earth: Theories and Explanations

2. 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.

Fossil Evidence for Biological Diversity, Speciation, & Mass Extinction

3. Fossil Evidence for Biological Diversity, Speciation, & Mass Extinction

One of the best sources of evidence we have for evolution is the fossil record. Fossils provide a wealth of information on how species change over time and for exciting events like mass extinctions and new species formation.

What is Classification in Science? - Definition & System

4. What is Classification in Science? - Definition & System

In order to understand things in science, we need organization. Because science is such a large umbrella term, we have to organize it into different topics. Learn more about classification in science, and take a quiz to test your knowledge.

Cladograms and Phylogenetic Trees: Evolution Classifications

5. Cladograms and Phylogenetic Trees: Evolution Classifications

Family trees help show how people are related to each other. Similarly, scientists use cladograms and phylogenetic trees to study the relationships between organisms.

Scientific Evidence That Supports Evolution

6. Scientific Evidence That Supports Evolution

Evolution explains how species that are present on Earth today are modified descendants of their ancestors. This scientific theory is supported by many different types of evidence, which show how evolution is a very real and natural phenomenon.
