Students explain the basics of evolution by natural selection. They calculate allele frequencies as they relate to inheritance. They explain the Hardy-Weinberg Law and how evolution takes place when this law is not in place.

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...

New Review Color Vision Genetics Evolution Simulation
At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

Population Genetics: When Darwin Met Mendel
Learners explore population genetics, or how populations of species change over time, leading to evolution with a video that brings together the principles of Mendel and Darwin and explains and models the Hardy-Weinberg equation.
