Generation
External — Free Natural Selection Simulation — PhET Colorado

Control mutation rate, population size, and predator pressure across multiple generations. Directly observe allele frequency change — a core requirement of VA SOL BIO.7b.

Opens in a new tab. Free, browser-based, no login required.

External — Free Exploring Transitional Fossils — HHMI BioInteractive

Examine fossils of prehistoric vertebrates including transitional forms, and compare anatomical features across fish, tetrapods, and transitional skeletons. Connects fossil evidence directly to common descent and SOL BIO.7b.

Opens in a new tab. Free educator and student resource from Howard Hughes Medical Institute.

External — Free Lizard Evolution Virtual Lab — HHMI BioInteractive

Analyze real field data from lizard populations in the Bahamas. Measure how predation changes body characteristics over generations — a powerful real-world example of natural selection in action.

Opens in a new tab. Uses real scientific data from published research.
