Be sure to record the data that you need to complete the table if you have been assigned the Pre-Lab questions.Once the time is up clicking on a moth will no longer allow you to catch it (there is nothing wrong with the simulation -your time is up). You (the predator) will have 15 seconds to find and catch as many moths (the prey) as you can by clicking on them.At the start of the simulation the moths are on a pattern background similar to the bark of a tree.50 of those moths will be the 'Peppered' color variation and 50 will be the 'Black' color variation (they are the same species of moth, these are just color variation within the population). When you first open the simulation there will be a total of 100 moths.Once you open the simulation the timer will start counting down immediately - so get ready to start catching moths immediately!.Before you start the simulation there are some things you need to know, so make sure you read this section carefully.Below is a link to a simulation of what happened to the Peppered Moth population before and after the industrial revolution.This is evolution - a change in a population over time.After the industrial revolution the soot covered tree barks camouflaged the dark colored moths and their numbers increased.

Before the industrial revolution the dark colored moths stood out against the lighter colored bark and were eaten more often.There are 2 color variations of the Peppered moth a dark color and a lighter color.Another example is the change in the Peppered moth population.
