Witnessing Evolution First-hand: A K-12
Laboratory Exercise in Genetics and Evolution Using Drosophila. American

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 (in collaboration with Mika Hunter) 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
sells a kit based on this activity, called the Natural Selection with Drosophila kit. A manuscript describing these activities is in press (click here for associated materials).
Witnessing phenotypic and molecular evolution in the fruit fly. Evolution: Education and Outreach, 5: 629-634. Authors: Caiti S S Heil, Mika J Hunter, Juliet KF Noor, Kathleen Miglia, Brenda Manzano-Winkler, Shannon R McDermott, and Mohamed AF Noor
Building on the K-12 activity above, we have an advanced portion wherein students use standard molecular biology techniques like PCR and gel electrophoresis to witness the impact of a spreading red-eye allele in their experimental populations. They amplify markers and see "hitchhiking" of alleles at markers near to, but not far from, the spreading red-eye allele. This activity goes beyond the standard "let's do PCR" that is often done in introductory laboratories such that they still learn the technique, but with a lesson and "purpose" to it in mind.
