About This Chapter

The Evolution chapter of this AP Biology Tutoring Solution is a flexible and affordable path to learning about evolution. These simple and fun video lessons are each about five minutes long and they teach all of the information involving evolution required in a typical AP biology course.

How it works:

  • Begin your assignment or other AP biology work.
  • Identify the evolution concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our AP biology tutoring solution will benefit any student who is trying to learn evolution and earn better grades. This resource can help students including those who:

  • Struggle with understanding the theory of evolution, evidence for evolution, types of natural selection or any other evolution topic
  • Have limited time for studying
  • Want a cost effective way to supplement their science learning
  • Prefer learning science visually
  • Find themselves failing or close to failing their evolution for AP biology unit
  • Cope with ADD or ADHD
  • Want to get ahead in AP biology
  • Don't have access to their science teacher outside of class

Why it works:

  • Engaging Tutors: We make learning evolution simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live biology tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn evolution on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

Learning Objectives

  • Become familiar with the theory of evolution.
  • Describe the evidence for evolution.
  • Understand how to determine the rates of evolution.
  • Discuss Hardy Weinberg equilibrium.
  • Learn how natural selection and adaptation occur.
  • List the different types of natural selection.
  • Compare and contrast allopatric and sympatric speciation.
  • Describe the prezygotic and postzygotic barriers to speciation.
  • Learn how random mutation can lead to genetic variability.
  • Take a look at peppered moths as an example of rapid adaptation.
  • Understand how artificial selection affects evolution.

Theories of Evolution: Lamarck vs. Darwin

1. Theories of Evolution: Lamarck vs. Darwin

Jean-Baptiste Lamarck and Charles Darwin each had their own theories of evolution. Explore the principles of Lamarckian and Darwinian evolution in population genetics, using flying hamsters as examples.

Evidence for Evolution: Paleontology, Biogeography, Embryology, Comparative Anatomy & Molecular Biology

2. Evidence for Evolution: Paleontology, Biogeography, Embryology, Comparative Anatomy & Molecular Biology

There is much support for the theory of evolution. This evidence comes from a variety of scientific fields and provides information that helps us trace changes in species over time. In this lesson, we'll look at this evidence and explore how it supports the theory of evolution.

Rates of Evolution: Punctuated Equilibrium & Molecular Clock Hypothesis

3. Rates of Evolution: Punctuated Equilibrium & Molecular Clock Hypothesis

In general, evolution is a very long process. But rates of evolution can be different for different organisms. In this video lesson, you will identify how scientists study rates of evolution and fill in some of the missing 'steps' in the fossil record.

Hardy-Weinberg Equilibrium I: Overview

4. Hardy-Weinberg Equilibrium I: Overview

The Hardy-Weinberg equilibrium represents the conditions necessary to predict the frequency of certain genotypes within a population. Explore the five criteria of Hardy-Weinberg equilibrium and their importance in population genetics.

Hardy-Weinberg Equilibrium II: The Equation

5. Hardy-Weinberg Equilibrium II: The Equation

The Hardy-Weinberg equilibrium equation helps in analyzing and understanding the gene pool of a population. Learn about this equation, including the variables it represents and where to find these variables, understand alleles and genotypes, and explore the significance of allelic and genotypic frequencies.

Hardy-Weinberg Equilibrium III: Evolutionary Agents

6. Hardy-Weinberg Equilibrium III: Evolutionary Agents

Learn about the Hardy-Weinberg equilibrium and how it is used to determine if a particular population is in equilibrium. Understand the role of the evolutionary agent with two examples, the genetic drift, and the term population bottleneck.

Natural Selection & Adaptation: Definition, Theory & Examples

7. Natural Selection & Adaptation: Definition, Theory & Examples

Evolutionary fitness is a trait's ability to change the contribution of offspring by an individual for the next generation. Explore natural selection, adaption, and the different traits that determine fitness in this lesson.

Natural Selection: Definition, Types & Examples

8. Natural Selection: Definition, Types & Examples

Natural selection is a process in the evolution and adaptation of organisms to increase primary characteristics. Learn about the process of natural selection, the different types of natural selection, and the concept of polymorphism.

Speciation: Allopatric and Sympatric Speciation

9. Speciation: Allopatric and Sympatric Speciation

A species is a particular group of organisms. Speciation is the process of a species splitting into new species. Discover the two different types of speciation - allopatric or geographic speciation, and sympatric speciation.

Prezygotic Reproductive Barriers & Speciation: Definition & Examples

10. Prezygotic Reproductive Barriers & Speciation: Definition & Examples

Prezygotic barriers prevent the fertilization of an egg cell. Explore the types of prezygotic barriers - spatial isolation, temporal isolation, mechanical isolation, gametic isolation, and behavioral isolation.

Postzygotic Reproductive Barriers: Definition & Examples

11. Postzygotic Reproductive Barriers: Definition & Examples

Postzygotic reproductive barriers reduce the reproductive capacity of hybrid offspring. Discover the three types of postzygotic barriers - hybrid zygote abnormality, hybrid infertility, and low hybrid viability.

Genetic Variability and Random Mutation

12. Genetic Variability and Random Mutation

Evolution is driven by variation among populations. The amount of variability determines how well a population can adapt to environmental changes, while random mutations can provide new variations that help a population adapt to unexpected changes.

An Example of Rapid Adaptation: The Peppered Moths

13. An Example of Rapid Adaptation: The Peppered Moths

Normally, adaptations occur over thousands or millions of years. However, drastic changes in the environment can shorten the time period in which a change comes about. In such cases, we can learn a lot about the evolutionary process and how natural selection drives it forward.

Artificial Selection in Evolution

14. Artificial Selection in Evolution

Humans have been selectively breeding for desirable traits in plants and animals for a long time. This artificial selection allows for a lot of control in the breeding process but can also lead to unintended mutations within a population of organisms.

Founder Effect: Example & Definition

15. Founder Effect: Example & Definition

The founder effect is defined as reduced variations in genetics among a small subset from a larger population. Learn more about the logic behind the founder effect, and learn about how the founder effect and global founder effect work by considering some of the provided examples.

Habitat Fragmentation: Effects, Definition & Causes

16. Habitat Fragmentation: Effects, Definition & Causes

Civilization development, such as roads and housing, have conflicted with nature for thousands of years and also has had a signficant impact on the environment. Learn about this process of separating organisms from their resources called habitat fragmentation, the dire implications for the habitat and biodiversity, and potential solutions.
