Theories of Evolution: Lamarck vs. Darwin

1. 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.

Natural Selection & Adaptation: Definition, Theory & Examples

2. 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.

Evolutionary Change: Definition and Forms

3. 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.

Scientific Evidence That Supports Evolution

4. 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.

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

5. 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.

Divergent & Convergent Evolution: Definitions & Examples

6. Divergent & Convergent Evolution: Definitions & Examples

Two types of macroevolution are essential to the understanding of evolutionary theory. Explore this lesson and learn more about convergent evolution and divergent evolution.

Artificial Selection in Evolution

7. 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.

Coevolution: Examples & Definition

8. Coevolution: Examples & Definition

Can you imagine having a tongue three times the length of your body? There actually exists a moth with such a tongue, and it evolved due to the features of a flower that it feeds on. Learn about this and other examples of organisms that have evolved together.
