How Does Evolution Work?
In this activity, students will take part in an online simulation of classic work performed by John Endler on guppies. The students will collect data, formulate a hypothesis, and run a series of experiments. Students will find out about the interplay between natural selection and sexual selection in a simulated population of guppies.
