Lactase Persistence: Evidence for Selection
What's the link between lactase persistence and dairy farming? Biology scholars analyze data to find evidence of the connection, then relate this to human adaptation. Working individually and in small groups, learners view short video...

Evolution and Adaptations
Survival of the fittest isn't just for the movies! A five-part lesson explores several different species with known adaptations and analyzes them for their survival strategies. Using both video and research data, scholars draw...

Modeling the Regulatory Switches of the Pitx1 Gene in Stickleback Fish
Gene switches work similarly to light switches in controlling one feature of their environments. Scholars study the Pitx1 gene in a specific type of fish. They learn the different ways this switch controls various body parts and...

Stickleback Evolution Virtual Lab
How quickly do animals evolve? Can comparing different samples of the same fossil answer timeline questions? Scholars use virtual labs to examine fossils and learn about stickleback evolution. They compare pelvic morphology in lakes...

Stalking the Genetic Basis of a Trait
Need an a-maize-ing lesson to show your class how regulatory genes work? If you use the well-written resource, they'll be all ears! Biology scholars discover the gene responsible for the evolution of the modern-day corn plant through a...

Patterns in the Distribution of Lactase Persistence
We all drink milk as babies, so why can't we all drink it as adults? Examine the trend in lactase production on the world-wide scale as science scholars analyze and interpret data. Groups create pie charts from the data, place them on a...
