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...
Curated OER
The Effect of Natural Selection on Genes, Traits and Individuals
Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

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...

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...
Howard Hughes Medical Institute
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...
Howard Hughes Medical Institute
Testing a Hypothesis
Are sickle cell disease and malaria related somehow? Scholars learn about both illnesses and the hypotheses that they are related. They discuss, view a video, and answer questions to demonstrate understanding. The resource includes an...

Discovering the Wallace Line
When studying locations of specific species, interesting patterns emerge. Young scholars discover this as they plot the location of specific species on a group of islands. Patterns emerge as they identify the Wallace Line. They then...

Developing an Explanation for Mouse Fur Color
Whether or not you think mice are nice, you'll love the colorful activity! Scholars examine evidence for evolution in the rock pocket mouse through video, discussion, and collaborative work. Learners watch a video regarding variation in...

Seed Dispersal in Tropical Forests
How do seeds get around? It's not like plants can control seed dispersal—or can they? Dig deeper into the amazing mechanisms of seed dispersal observed in tropical plants through interactives, a video, and plenty of hands-on data...

Using Molecular and Evolutionary Biology to Understand HIV/AIDS and Treatment
HIV mutates rapidly, making treatments challenging to find. Scholars learn about why it mutates so quickly and how scientists race to find treatments. The resource approaches the issue from both a molecular and evolutionary perspective...

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...

Ebola: Disease Detectives
How did the Ebola virus first infect humans? Young virologists examine genetic sequences from the 2014 Sierra Leone outbreak to find similarities during a riveting activity. Following similar methods used by MIT and Harvard, partners...

The Ecology of Lyme Disease
Areas that previously included no risk of Lyme disease now have cases every year. Scholars learn about the spread of Lyme disease and the relationship with ecological succession. Then, they discuss possible solutions using the known food...

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...
What happened to the frogs?
Students will select ten rubber frogs and determine their pollutant source based on their malformations. Students will write a brief essay on their findings. Students will be engaged in the lesson the entire time!
Howard Hughes Medical Institute
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...

Vitamins and Health – Why Experts Disagree
Should people take vitamins or get the needed minerals through diet? Experts disagree based on many different factors. Scholars compare study findings and discuss the differences. They learn the importance of comparing results across...
