Witnessing Evolution First-hand:
K-12 and College Laboratory Exercises in Genetics and Evolution Using Drosophila

Caiti S Smukowski, Brenda Manzano-Winkler, Mika J Hunter, Juliet KF Noor, and Mohamed AF Noor

Despite its fundamental importance to all of biology, the science of biological evolution has been under attack for decades, and Durham public schools are no exception. In the 2006 Durham school board election, an incumbent school member said at a public debate that evolution was "racist" and that she was strongly opposed to it being taught. 40% of respondents from a poll in an AP Biology class at Riverside High School said that evolution was not a proven fact- specifically answering that "no sort of evolution has clearly happened."

To address this deficiency, the Noor laboratory developed a series of exercises wherein students observe evolution by natural selection in a fruit fly population. Working in pairs, students start with populations of white-eyed fruit flies but then add a single advantageous "mutant" red-eyed male. Over three generations, the red-eye trait spreads in the population, and the students observe this and quantify it.

Importantly, this observed spread is only the most basic element of this laboratory exercise. While observing it, the students learn about linkage and X-chromosome inheritance, and in some versions, they learn and "use" molecular biology protocols including PCR and gel electrophoresis. Hence, the demonstration is a launching point for learning many fundamental principles of evolution and genetics.

This exercise has been implemented now in multiple schools (middle schools, high schools, and even in introductory college courses). It was presented at the North Carolina Science Teachers Association Professional Development Institute conference and at the Society for the Study of Evolution annual conference. Further, Carolina Biological Supply has agreed to sell a kit based on it, called the Natural Selection with Drosophila kit. A manuscript describing these activities has been submitted.
