Data PointsScientists used SNP genotyping in populations of freshwater stickleback fish to determine the genetic mutations responsible for the impaired development of pelvises and spines.
Data PointsScientists collected bacteria from locations that had never been exposed to humans or modern antibiotics to determine if antibiotic resistance is newly evolved since the introduction of antibiotics or has evolved independently.
Data PointsResearchers exposed arthropod mimics that use a golden patch to warn of unpalatability to predators with different prey preferences to determine how effective their warnings were.
Data PointsRosemary and Peter Grant studied the change in beak depths of finches on the island of Daphne Major in the Galápagos Islands after a drought.
ActivitiesA worksheet that guides students through The Stickleback Evolution Virtual Lab. The virtual lab lets students learn firsthand the methods for analyzing body structure in stickleback collected from lakes and fossils recovered from a quarry. Students measure, record, and graph their results to discover evolutionary patterns.
