Bringing a realistic model of natural selection and evolution into your classroom has never been easier. Using the model organism Drosophila melanogaster, students introduce a single advantageous "mutation" (red eyes) into a population of white-eyed "ancestral" strain flies. They then observe and calculate the new trait's spread and the shift in population phenotypes over generations. The fitness advantage offered by the "mutation" classically exhibits evolution by natural selection—and your students can see it happen right in the classroom. This kit is designed for 32 students working cooperatively in 8 groups of 4. It includes digital resources to support 3-dimensional instruction for NGSS and perishable materials.

Note: Keep Drosophila cultures at room temperature; do not refrigerate. Please order at least 2 weeks in advance of desired ship date.
