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 taxonomy and the evolution and classification of organisms
- 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 the evolution and classification of organisms
- 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 evolution and classification of organisms 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 evolution and classification of organisms chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any question about the evolution and classification of organisms. 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 an evolution and classification of organisms unit of a standard high school biology course. Topics covered include the evolution of:
- Prokaryotes, including archaebacteria and eubacteria
- Protists and evolution
- Evolution of fungi and plants
- Evolutionary history of animals
- Human evolution
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.
8. Autotrophs: Definition, Examples & Types
As human beings, we need to eat living things for energy. Other organisms are able to make their own food. Autotrophs can provide energy sources for themselves as well as for those of us who can't produce it on our own.
9. The Three Domains of Life
Biology is a rather mysterious thing. How are we related to fish? How can you say we are related to amoebas? We will explore the idea of taxonomy here, sticking with the most generalized concept, the domain.
10. Types of Symmetry in Animals
Scientists use symmetry to identify and group animals into categories. This lesson describes the types of symmetry found in animals. You will learn about what each type of symmetry looks like, as well as how to identify them in different animals.
11. Chemoautotrophs: Definition & Examples
We are going to get a working definition of chemoautotroph and look at some examples of organisms that are classified as chemoautotrophs. We will cover the importance of chemoautotrophs in our world.
12. The Heterotroph Hypothesis: Definition & Overview
A hypothesis is an educated guess supported by research. In this lesson, we will learn about the heterotroph hypothesis and explore how the first cells on Earth could have come about and used energy to survive.
