Read full description

The virtual lab includes four modules that investigate different concepts in evolutionary biology, including adaptation, convergent evolution, phylogenetic analysis, reproductive isolation, and speciation. Each module involves data collection, calculations, analysis and answering questions. The “Educators” tab includes lists of key concepts and learning objectives and detailed suggestions for incorporating the lab in your instruction. The lab is appropriate for students in high school biology and environmental science classes, and undergraduate biology, ecology, environmental science courses. The focus on observation, measurement, and experimental methods makes the lab a good fit for addressing "science as a process" or "nature of science" aspects of the curriculum. The emphasis on the collection, analysis, and graphing of data, connects to the mathematical dimension of biology and general goals of STEM integration. The Howard Hughes Medical Institute (HHMI) is a nonprofit medical research organization that ranks as one of the nation's largest philanthropies. HHMI plays a powerful role in advancing biomedical research and science education. HHMI brings the latest biomedical research into the classroom with the award-winning BioInteractive website, featuring free resources for science education, including lectures, animations, short films, interactive features, and classroom-ready lesson plans and activities. Topics include all areas of biology and earth and environmental science. Vist the website at www.biointeractive.org.

ReceptionRating · Positive reviews · Number of ratings

Lizard Evolution Virtual Lab holds the better App Store score, 1.9 against 1.5. That said, the two scores are not equally well evidenced: Lizard Evolution Virtual Lab has 22 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 71% of Pearl Diver HD's written reviews are positive against 24% of Lizard Evolution Virtual Lab's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Pearl Diver HD ships an update every 20 months, Lizard Evolution Virtual Lab every 14 months. The most recent releases landed on November 1, 2026 and October 29, 2026 respectively.
