| Resource Description
|
| NATURAL SELECTION EXPERIMENT KIT. Over a hundred year time period, the peppered moth population in England shifted from predominantly light-colored moths to predominantly dark-colored moths. Kettlewell reasoned that predatory birds fed on more light-colored moths than on dark-colored moths because the light-colored moths were more easily spotted against pollution-darkened tree bark. Students conduct two labs that demonstrate how environmental conditions affect population dynamics. Reusable supplies for 30 students, grades 8-10. #KIT-14097.
