Students use a mathematical simulation of genetic drift to answer questions about the factors that influence this evolutionary process. They run a series of simulations varying allele frequency and population size and then analyze their...

You may not know if that zebrafish in your fish tank is a model citizen—but it is definitely a model organism! What can we learn about ourselves from a tiny zebrafish? Discover more about the polygenic trait of skin color through a...

Students examine mechanisms behind biological evolution and the theories that feed it, and are able to demonstrate their knowledge of these theories in a story.
