The Chips Are Down: A Natural Selection Simulation

Are you the predator or the prey? Student groups participate in an activity to demonstrate the process of natural selection in a contained environment. After scholars complete the activity and questions, they apply their knowledge to a...

Charles Darwin and Jean Baptiste Lamarck are credited for developing the theory of natural selection. After teaching your beginning biologists about acquired characteristics, they read the included selection and answer questions that...

Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

Introduce the topic of evolution and natural selection with visuals, vocabulary, and historical perspective. Budding biologists can examine the evidence on their own by going through the presentation, or the teacher can present to the...

Natural selection—good things come to those who mate. The video introduces the idea of natural selection. Then it details three types: directional, stabilizing, and disruptive. It includes both graphs and examples for each type.

The evidence for natural selection is presented as a random variation of a characteristic allowing a particular strain of organism to survive with a higher probability of successful reproduction. Population change over a short period of...

The lecturer describes how certain characteristics develop. In this case, he discusses eye marking. The impact of environmental factors plays a huge role in the probability of successful reproduction and the fact that favorable genes...

Examine exactly what is meant by natural selection, as well as how it works in nature and through the assistance of humans. Presented with fun graphics and simple narration, the complex topic of natural selection is clearly explained in...

Viewers explore real-world examples of both evolution and natural selection as the instructor discusses changes to the environment, mutations causing changes in phenotypes and changing the fitness in organisms, and how humans are...

Can human activity influence the colors of moths? The simulation explains how pollution changed the color of tree bark, which led to the survival of a different variation of moths. It also discusses the shift back as air quality improves.
