Answer 7

This hands-on laboratory exercise is a highly simplified model that attempts to simulate evolution by means of natural selection. Predators will act as agents of selection on their prey, a species whose members vary in color. We will assume that color is an inherited trait. Small squares of paper will represent the prey, which will be spread out of a piece of printed colored fabric that will serve as the habitat. The predators (you) will prey upon the population, with the surviving members reproducing and passing along the genes for color.

Problem:

How does a population change as a result of natural selection?

Materials:

5 different colors of paper cut into 1 cm × 1 cm squares (at least 100 squares of each color)
Multicolored fabric or newspaper, approximately 1 meter × 1 meter
1 or 2 partners (friends or family)
Procedure:

The prey will be represented by the small 1 cm × 1 cm squares of paper and the habitat is represented by the 1 meter × 1 meter piece of fabric. Hypothesize which color prey you think is most likely to be captured by the predator and which color prey is most likely to survive, and then record your hypothesis. Be sure that your hypothesis includes explanations for your predictions.
Have the two partners (prey) stand with their backs to the habitat while you scatter 20 squares of each color randomly on the fabric. Try to achieve a uniform distribution, and be sure to separate any that are clumped together.
Have the partner(s) randomly pick up the prey as fast as they can. Have them stop when they have collected a total of 75 prey, leaving the other 25 remaining in the habitat.
Count the number of survivors of each color. Each surviving prey has three offspring of the same color, bringing the total population back up to 100. Record the number of each color in the next generation in your data table.
Count out the correct number of each colored prey and scatter them on the fabric. Repeat the process two more times, for a total of three generations.

im trying not to cut all 500 sheets of paper is there anyway around this

Answer 8

Just for future reference, next time you have a question in biology type it into the biology section in OpenStudy: http://openstudy.com/study#/groups/Biology

Answer 9

im sorry haven't done this and im not sure how to help. I sugest looking on youtube for come people who completed this project

Answer 10

im very sorry

Answer 11

I remember doing this problem a year or two ago.... It certainly was a pain in the butt. What I did to make it a little simpler was instead of using the full 500 little cut outs of paper, I only used half that and divided all the other numbers by two as well. In the end you still have to go through the steps and if you still dont want to cut 250 sheets then divide even more

This question is being closed because its unrelated to history section. Repost it in biology section.
Thank you.
