Procedure
Part A:
Evolution, Adaptations & Natural Selection

• Answer the Questions in Part A of Lab 7 Lab Report.

Part B:
Ecology

• Answer the Questions in Part B of Lab 7 Lab Report.

Part C:
Coevolution: Predator- Prey Interactions

• Use this virtual Predator-Prey interaction to gather data for the Hawk and Mouse populations over 30 generation and answer questions in Part C of Lab 7 Lab Report.

Predator-Prey Interaction Part 1 (generations 0-15)Predator-Prey Interactions Part 2 (generations 16-30 & graph)

• Fill in the Table below, take a picture of the completed table for Part C of 7 Lab Report.
I have filled in the data for "generation 0" already
• After the 30th generation you will obtain a graph of the hawk and Mice populations. Upload this graph to complete question 11.
• Use the graph to answer question 12.

Image is a table. The top row of the table reads Hawk and Mice, each of these is broken into sub-columns. Hawks has three columns labeled total, starved and babies. Under mice there are two columns labeled total and caught. Along the left side of the table, it reads Generation. Below generation are rows labeled 0 through 30. Generation zero is filled in with the following data: Total hawks 1, staved hawks 1 and baby hawks 0. Total mice 3 caught mice 0.

Part D:
The effects of environmental change on a population

• Below is a link to a simulation of what happened to the Peppered Moth population before and after the industrial revolution.
• Before you start the simulation there are some things you need to know - so make sure you read this section carefully.
• Once you open the simulation the timer will start counting down immediately - so get ready to start catching moths immediately!
• When you first open the simulation there will be a total of 100 moths. 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).
• At the start of the simulation the moths are on a pattern background similar to the bark of a tree.
• You (the predator) will have 15 seconds to find and catch as many moths (the prey) as you can by clicking on them.
• You do not need to watch the timer. 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).
• Be sure to record the data that you need to complete the table in Part D of the Lab Report.
• Once you have collected your data select "Next Round". The Killing field will repopulate itself with 100 moths, but every Black moth you caught in the previous generation/round will be replace with a Peppered moth.
• After 3 generation/rounds see what happens when the Industrial Revolution covers the tree trunk with black soot!
• Collect data for 3 more generations/rounds after the background turns black.
• Then continue catching moths until there are no more of the Peppered color variation. You do not need to collect all the data for these. See how many generations it takes you to drive the Peppered color variation to extinction.
• Once you have driven the Peppered color variation to extinction you can stop on navigate back to this tab.
