Question: How do different variations lead to evolution of species?
We have learned that mutations and sexual reproduction can lead to variations. Variations that allow an organism to survive in its environment are considered adaptations. The variation with the best adaptation for the environment will survive and reproduce while the others will eventually die off. If the environment changes, a different variation may survive instead. For your final project you will model this in a lab assignment.
Background Information:
Pretend there is an organism on earth called a weezy. There are three variations of weezys: ones with two arms and hands with five fingers (weezy A), ones with one arm and hand with five fingers (weezy B), and ones with one arm and hand with three fingers (weezy C).





Weezys are eaten by smurfs. To protect themselves from smurfs, weezy's build towers out of rocks and climb up to the top of them. Because smurfs can’t climb, the weezys are safe if they manage to get to the top. However, weezys must build their towers quickly because smurfs are extremely fast. The ones who build their towers quickly enough survive, but the ones that are too slow usually get killed by smurfs.
In this activity, you will simulate the three variations of weezys in a population. You will measure how long it takes you to build the tower while pretending to be each type of weezy. You will do three trials for each weezy. As you are doing the activity, complete the data table below. When you are finished, answer the questions that follow.
Model:
Identify what you will use to represent the rocks for your tower. (You need 10)
Write your material here:
Describe how you will model weezy C.

Analysis Questions
Directions: Use your data to answer the following questions.
