Helen Snodgrass describes how she uses BioInteractive's The Biology of Skin Color film and "Evidence for Selection" activity to show students how humans have evolved over time.

Robin Bulleri describes how she uses the Got Lactase? short film, along with the "Inheritance of Lactose Intolerance" activity, to show her students how lactase persistence arose and how pedigrees and DNA analysis reveal patterns of inheritance of lactase gene variants.

Paul Strode describes the BioInteractive Click & Learn activity on DNA sequencing and phylogenetic trees. He explains how it teaches students about DNA sequence alignment, and how those sequence differences allow researchers to determine relationships between species.
