Stickleback Evolution

This model simulates the contemporary evolution of threespine stickleback in Loberg Lake, Alaska.

Stickleback Evolution--Eda gene

This model simulates the contemporary evolution of threespine stickleback in Loberg Lake, Alaska. Users can examine the changes in allele frequencies over time. Suggested for college-level students.

Cattle Body Size Evolution

In this model you will investigate the evolution of cattle body size affected by different selection mechanisms.

Selection in Guppies

In this model you will investigate guppy coloration patterns in various habitats and infer the underlying selection mechanisms.

Genetic Drift & Natural Selection

In this model you will investigate the changes in allele and genotype frequencies affected only by genetic drift and by both genetic drift and natural selection.

Coevolution

This is a simulation modeling the process of coevolution. Users may also observe different evolutionary patterns by adjusting the speed mutation extent in prey and/or predator populations.

Speciation

Investigate the effects of different factors on the evolution of coloration in a simulated fish population, especially the divergence in allopatry and sympatry.

Hardy-Weinberg Equilibrium

In this model you will explore various conditions in which HW is violated and learn how the allelic and genotypic frequencies change under these conditions.

Human Skin Color Evolution

How does UV affect human skin color evolution through the effect of folic acid and vitamin D on human reproduction and survival? Test your ideas in this model.

Evolution of Antibiotic Resistance

This model reveals the same scenario in the giant petri dish experiment on the evolution of antibiotic resistance. Mutation and reproduction rates are included to expand student's exploration to the process.

Galapagos Finches

Investigate the effect of different food resources on finch beak depth in this model.
