Ch 11: Evolution & Natural Selection for the MCAT: Tutoring Solution

About This Chapter

The Evolution and Natural Selection chapter of this MCAT Prep Tutoring Solution is a flexible and affordable path to learning about evolution and natural selection. These simple and fun video lessons are each about five minutes long and they teach all of the topics involving evolution and natural selection required for the MCAT exam.

How it works:

  • Begin your review or other MCAT preparation work.
  • Identify the evolution and natural selection 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 MCAT Prep Tutoring Solution will benefit any student who is trying to learn about evolution and natural selection and prepare for the exam. This resource can help students including those who:

  • Struggle with understanding natural and group selection, the theory of evolution, symbiotic relationships, carrying capacity or any other evolution and natural selection topic
  • Have limited time for studying
  • Want a cost effective way to supplement their MCAT preparation
  • Prefer learning science visually
  • Find themselves struggling with evolution and natural selection
  • Cope with ADD or ADHD
  • Want to get ahead in preparing for the MCAT
  • Need access to MCAT review materials

Why it works:

  • Engaging Tutors: We make preparing for the MCAT exam 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 MCAT prep tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Review evolution and natural selection 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

  • Learn how the different types of natural adaptation and natural selection work.
  • Provide a definition for differential reproduction.
  • Explain how new species form.
  • Describe the different types of ecosystems.
  • Discuss interspecific competition and symbiotic relationships.
  • Study the relationship between carrying capacity and population movement.
  • Understand the fields and tools used to classify and study evolutionary change.
  • Summarize the main theories behind the origin of life on earth.

Natural Selection & Adaptation: Definition, Theory & Examples

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

How does natural selection help shape the amazing types of animals we witness around us? In this lesson, we'll explore adaptations and what they can tell us about a species' past evolution.

Natural Selection: Definition, Types & Examples

2. Natural Selection: Definition, Types & Examples

We'll take a look at the types of natural selection that can occur. From flying hamsters to moths, you'll start to grasp the different paths organisms can take as they respond to their changing environments over time.

Speciation: Allopatric and Sympatric Speciation

3. Speciation: Allopatric and Sympatric Speciation

Discover the definition of a species and learn more about how species split. Find out common terms related to the splitting of species and study what role polyploidy plays in the development of a species.

Prezygotic Reproductive Barriers & Speciation: Definition & Examples

4. Prezygotic Reproductive Barriers & Speciation: Definition & Examples

We may take for granted why animals choose to mate with other animals of similar appearance, but it's not that simple. There are actually biological barriers to reproduction that can prevent even seemingly closely related species from reproducing. This lesson looks at one such category of hindrances, prezygotic barriers, which make fertilization impossible.

Postzygotic Reproductive Barriers: Definition & Examples

5. Postzygotic Reproductive Barriers: Definition & Examples

Do flying hamsters represent a separate species from your run-of-the-mill hamsters? We'll get to the bottom of this by performing crosses between the two hamster types. You'll explore postzygotic reproductive barriers and their possibly tragic consequences.

Theories of Evolution: Lamarck vs. Darwin

6. Theories of Evolution: Lamarck vs. Darwin

We'll look at the interplay between population genetics and environment. Are traits individually acquired or do entire populations evolve? The flying hamsters and a few other notable experiments will provide the answers.

Ecosystems, Habitats and Ecological Niches

7. Ecosystems, Habitats and Ecological Niches

Check out this video lesson to understand the many complex aspects of an ecosystem. See how animals live in habitats and survive amongst their surroundings.

Symbiotic Relationships: Mutualism, Commensalism & Parasitism

8. Symbiotic Relationships: Mutualism, Commensalism & Parasitism

If your cat or dog has ever had fleas, you've witnessed symbiosis in action. In this lesson, learn the many types of symbiosis in biology, and how these relationships can have a positive, negative, or neutral effect on the individual species.

Interspecific Competition, Competitive Exclusion & Niche Differentiation

9. Interspecific Competition, Competitive Exclusion & Niche Differentiation

What happens when two similar species that consume the same resources occupy the same space? Interspecific competition, that's what! Watch our video lesson to learn about the outcomes of this ecological battle.

Carrying Capacity, Migration & Dispersion

10. Carrying Capacity, Migration & Dispersion

Have you ever wondered why some types of birds fly south in the winter or why some animals form territories? Watch this video to learn about a species' maximum growth capabilities, the way its members group themselves and why they might migrate to new locations every year.

Populations: Density, Survivorship and Life Histories

11. Populations: Density, Survivorship and Life Histories

Have you ever wondered how biologists determine the populations of animals in a particular geographic area? Watch this video lesson to find out, and discover how scientists look at the survivorship and life histories of many different species.

Cladograms and Phylogenetic Trees: Evolution Classifications

12. 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.

The Origin of Life on Earth: Theories and Explanations

13. 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.

Evolutionary Change: Definition and Forms

14. Evolutionary Change: Definition and Forms

You've probably heard of Charles Darwin and evolution. We know that evolution is change over time, but here we will look at how these changes may have occurred during Earth's history.
