The return of beavers to the British countryside is boosting biodiversity, reducing storm-induced flooding, and restoring wilderness to an over- manicured landscape.
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 video case study explores the approaches scientists used to identify a mutation that causes retinitis pigmentosa (RP), a progressive disease that leads to blindness.
This activity builds on information presented in the short film Genes as Medicine. Students interpret actual pedigrees to determine the inheritance pattern of Leber congenital amaurosis (LCA), an inherited form of blindness. They also examine protein sequence data to explore mutations that can cause LCA.
This activity explores an image of tattoo ink particles inside cells, which serves as a phenomenon for learning about the structure and color of human skin.
