The Making of the Fittest: Natural Selection in Humans
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...

Evolution by Natural Selection
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...

Artificially Selecting Dogs
Selective breeding has resulted in some novel and beautiful or useful dogs over the years. Using the American Foxhound as an example, genetics learners find out how and why they came about. Then, in small groups, they select breeds to...

Evidence of Evolution by Natural Selection
Being able to test a hypothesis is a scientific must. AP Biology pupils can see the process of hypothesis testing through evidence for evolution as seen in natural selection. Slides contain solid information and excerpts from academic...

The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture
Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

Natural Selection and the Evolution of Darwin's Finches
Darwin explained the connection between species of finches 150 years before scientists understood DNA. Technology and progressing science proved he was right, yet many struggle to understand how natural selection happens. Scholars use...

Natural Selection
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...

Selection and Variation in the Egyptian Origami Bird
Using origami paper birds, your biology class will experiment with mutations and natural selection to determine wing position, length, and width. It would be helpful to provide a worksheet to go with the activity that includes a...

The Making of the Fittest: Natural Selection and Adaptation
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...

A Model for Natural Selection- Spaghetti Worms
Does the early bird really get the worm? If so, which color of worm does it prefer? In an exciting and easy week-long field investigation, young field biologists set up a one square meter feeding area for birds. If you have a webcam,...

The Effect of Natural Selection on Genes, Traits and Individuals
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...

Evolution of Fur Color in Mice – Mutation, Environment and Natural Selection
Most species of animals include a variety of fur or hair color, but why? Scholars watch a video about a changing environment for mice. As the rocks around them change hues, different colors of mice begin to thrive. Discussion questions...

Allele and Phenotype Frequencies in Rock Pocket Mouse Populations
In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all...

Introduction to Natural Selection
Students develop an understanding of natural selection, specifically, how it unfolds from generation to generation. They work in small groups to perform an experiment using beans. They use a worksheet imbedded in this plan to guide their...

Natural Selection and Evolution of Rock Pocket Mouse Populations
Can evolution repeat itself? Scholars analyze amino acid data in two separate populations of mice. They learn that evolution repeats itself, but natural selection prefers some mutations over others in different environments. Analysis...
