This web simulation allows students to explore adaptive radiation of a fictitious group of birds called Pollenpeepers over a period of 5 million years. A hurricane blows some birds to 3 very different island groups and students identify the changes that take place over time and their causes including different climates, food, competition and predators. Each of the three island groups are compared to the original habitat with respect to topography, temperature, growing season and type of vegetation. Students read about the competition that the birds face when they arrive five million years ago, look at the amount of seeds, insects and flowers present and whether the number of predators is high, medium or low. They can then go forward in time a million years at a time and see the changes that have taken place in the population of pollenpeepers in each of these time periods. Instructions to operate the simulation are included as well as a species gallery where students can explore adaptive radiation in lemurs, Galapagos finches, Hawaiian silverswords, tenrecs and Hawaiian fruit flies.
