Adaptive Radiation of the Pollen Peeper (from: An Origin of Species WGBH Evolution Initiatives ) For interactive web module about the evolutionary theory of Adaptive Radiation. The objectives of this project are to explore adaptive radiation, the evolutionary process by which a single species can diversify into many species, all with different adaptive traits, and to understand the factors that push and/or allow for different populations of the same species to diverge and eventually become separate species. Here a fictitious bird, the Pollen Peeper (based similarly to the North American House Finch and the Honey Creeper), is used as a model.
