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...

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...

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...

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...

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,...

Comparing Theories: Lamarck and Darwin
Students compare the evolution theories of Lamarck and Darwin. They use self-assessment and a video to increase their knowledge of evolution theories. They research questions and present them to the class.

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...

Human Evolution
As the great and hilarious Tim Minchin once said, "Science is simply the word we use to describe a method of organizing our curiosity." Science is more than just a guess; it is based on questions, observations, and evidence. High...

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...

WHAT DARWIN NEVER SAW: Evolution, Science, Biology, Natural Selection
Students view video showing recent field work on a twenty two-year study of finch beaks on a small island in the Galapagos, showing natural selection clearly operating in the wild.

Human Skin Color: Evidence for Selection
Skin color is controlled by at least six genes. Young scientists learn about skin colors through a documentary. They discuss the topics of pigment, natural selection, and vitamin D absorption. They apply their knowledge to higher order...

A Simple Model for Natural Selection
Do you have what it takes to survive as a fit predator or will elusive prey lead to your extinction? Find out in a creative natural selection activity. Using different colors and shapes of grains to represent different species and...

Beans and Birds: A Natural Selection Simulation
High schoolers solve the following problem concerning the evolution of seed color in pinto bean plants: "How does natural selection change the frequency of genes or traits over many generations?" They use the constructivist approach to...

Genetic Variability
Using black and white construction paper, evolutionary biologists simulate the classic peppered moth study. They use beans in a frequency and natural selection exercise. Finally, they analyze germinated seeds for variations. All three...

Variations in Living Things
Biology beginners observe traits in a collection of plant parts to realize the tremendous amount of genetic variation within a species. They consider rules of nature and discuss what would happen if they changed. They also examine data...

Natural Selection And Evolution
Seventh graders investigate the concept of natural selection and its relationship to the theory of evolution. They conduct research using a variety of resources and use the information to create a class presentation and open up the...

Introduction To Natural Selection
Seventh graders investigate the concept of natural selection and it relation to the theory of evolution. They create a definition for classification based upon looking at other subjects that are similar. The variation of species is...

Natural Selection And Evolution
Students investigate the concept of evolution and how natural selection is used as an indicator that evolution has happened. They recognize the three effects it has on diversity and how adaptations can develop. Diversity is explained as...

Natural Selection
Kids act as scientists and preditors in this short natural selection activity; they collect and analyze data, then apply their new knowledge to real-world examples of natural selection. The layout of the worksheet is easy enough to use...
