"The Chuckabees" is an evolution simulation activity.
Dice and rulers are required.

OR... Don't have dice? Try this!

OR... Use this shuffler for ANY body part!
(Each person in a group can focus on one body part!)


Students roll dice to determine the characteristics of one chuckabee.

Class calculates the population's characteristics' averages.

Each group rolls a die to become geographically separated.

Students roll a die three times to see:

1st: Which characteristic "feels" selective pressure (yep... One characteristic at a time)

2nd: How this pressure affects the characteristic (simple math for speed)

3rd: How long the pressure affects the characteristic for (potential amplification of characteristics)
Repeat for 10,000 years. See: Sample Data
Students compare the ending population characteristics to the starting characteristics, and to other groups' ending characteristics by DRAWING them with cm rulers!
I included the end results of my first time doing it. See: Sample Chuckabees

Bottom: Ending Average Characteristics of Geographically Isolated Population (Notice the missing tongue? The last number ended up being zero!)
