The Chips Are Down: A Natural Selection Simulation

This editable worksheet is set up so that biology pupils read four case studies and identify points that are present in each, such as overproduction, heritable variation, struggle to survive, and differential reproduction. They also...

A diagram, data table, and reading passage top this resource. Through it, biology beginners are introduced to the concept of natural selection. They answer some questions and then participate in a simulation using fabric as a habitat and...

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...

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...

Clear up the confusion between natural selection and evolution with this cartoon. A hand draws diagrams and scenery as a voice narrates. This little feature is ideal for introducing these two concepts to beginning biologists.

Sickle cell disease only occurs when both parents contribute the trait, and mostly in those of African descent. Where did it come from? How did it evolve? Tony Allison, a molecular biologist, noticed a connection between sickle cell and...

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...

The pocket mouse can be light brown like the sands of the desert, or dark brown like the volcanic lava flows that are interspersed throughout New Mexico's Valley of Fire. It seems that predators have weeded out light colored mice in this...

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...
