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...

Natural Selection and Evolution of Rock Pocket Mouse Populations
Can evolution repeat itself? Scholars analyze amino acid data in two separate populations of mice. They learn that evolution repeats itself, but natural selection prefers some mutations over others in different environments. Analysis...

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

The Making of the Fittest: Natural Selection and Adaptation
The pocket mouse can be light brown like the sands of the desert, or dark brown like the volcanic lava flows that are interspersed throughout New Mexico's Valley of Fire. It seems that predators have weeded out light colored mice in this...

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...

Winogradsky Columns: Microbial Ecology in the Classroom
Winogradsky columns are ideal for observing the role of bacteria and other microorganisms in an ecosystem. This student activity guide is complete with data tables for observations and analysis questions for processing what was observed....
It's About Time
Natural Selection
Are you the predator or the prey? Student groups participate in an activity to demonstrate the process of natural selection in a contained environment. After scholars complete the activity and questions, they apply their knowledge to a...
