This film explores the evolutionary connection between an infectious disease, malaria, and a genetic condition, sickle cell disease.

In this activity, students investigate the phenomenon of lactase persistence by making sense of a series of data sets.

In this phenomenon-driven activity, students investigate how cells are signaled to make melanin and explain how mutations in melanin pathway proteins affect the coat color of various organisms.

In this activity, students interpret several pedigrees of autosomal dominant and recessive conditions and consider the benefits and limitations of genetic testing.

This video follows biologist Elinor Karlsson, who studies dogs to find genes associated with traits, including certain diseases.

In this inquiry-based activity, students engage in science practices to figure out why some people with a genetic condition that usually leads to sickle cell disease do not have disease symptoms.
 

This video presents an intriguing phenomenon: two patients who carry the same genetic variation, which is known to cause sickle cell disease, have very different outcomes.

This activity guides the analysis of a published scientific figure from a study that investigated how human populations might adapt to milk consumption, both genetically and culturally. 

This activity explores an image of fossil footprints at Laetoli, which serves as a phenomenon for learning about fossil evidence and human evolution.

This four-part animation series explores the biology of the virus SARS-CoV-2, which has caused a global pandemic of the disease COVID-19.

In this activity, students explore using CRISPR-Cas9 to knock out butterfly genes in order to determine their function.

This activity explores an image of a moth with unusual markings on its wings, which serves as a phenomenon for learning about mimicry and adaptation.
