About This Chapter
GRE Biology: The Diversity of Life - Chapter Summary
This chapter will familiarize you with details on the evolutionary histories of multiple organisms and the different organism types. These topics are taught in engaging video lessons that effectively demonstrate each concept through fun illustrations and graphics. You'll see the following topics covered in the chapter:
- Evolution of humans
- Cladograms and phylogenetic trees
- The evolution of plants and fungi
Each lesson features an available practice quiz that will give you some quick feedback regarding how well you're comprehending the information. These quizzes also use the same format as questions found on the GRE Science exam. Lesson transcripts are also available and feature key terms in bold, giving you a firm grasp of the lessons' most important points.
GRE Biology Objectives
You will find 190 multiple-choice questions on the GRE Biology subject test. Questions dealing with the diversity of life account for 6% of the total questions and are asked about in the organismal biology section. Passing the GRE Biology test can help you stand out among applicants for graduate school admissions. While not a requirement for applying to graduate school, it can be used to demonstrate your mastery of biology.
1. Taxonomy: Classification and Naming of Living Things
The name you give to a living thing may be completely different than the name someone else uses. In science, we use a common naming system for all living things to avoid confusion. This lesson will explore the basics of our classification system.
2. 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.
3. The Evolution of Prokaryotes: Archaebacteria and Eubacteria
The first living organisms on Earth were bacteria. These small organisms still exist today and are responsible for many things. In this lesson, we will explore both ancient bacteria and true bacteria.
4. The Evolution of Protists: Importance & Evolutionary History
Some organisms are very familiar. However, there are some that play vital roles in our lives that we don't even think about. We will look at a group of one of these unfamiliar kingdoms - protists.
5. The Evolution of Plants and Fungi: Characteristics & Evolutionary History
In early classification systems, plants and fungi were grouped together. While there are some similarities between these two kingdoms, there are some key differences that we will explore.
6. 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.
7. 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.
