How I teach Endler's evolution experiments (without PowerPoint)

The peppered moth of industrial England—and the Galapagos finches on Daphne Major during the 1976 drought—are common examples used for teaching natural selection. What unites them is their method: observational work.

John Endler's work, however, gives us insight into natural selection through experimental methods. Like the observational work just mentioned, his experiments showed the rapidity of natural selection when pressures change abruptly. Endler also pioneered evolutionary field experiments (Losos 2017).

Here's how I've taught Endler's experiments.
