3/10/14 Biology

     Yesterday in biology, we did a somewhat silly lab modeling natural selection. Two mats (habitats) were laid out on the ground, one black and one yellow. Twenty black pom-poms and twenty yellow pom-poms (prey) were scattered across each mat. Each person (predator) doing the lab were given a plastic test tube (their stomach) and either a fork or a spoon (their mouth). Then, all participants (again, predators) of the biology class were divided into two groups, one situated on each mat (habitat). For fifteen seconds, each person attempted to pick up (eat) as many pom-poms (prey) as the could using only their fork or spoon (mouth). Then, the pom-poms were tallied and more pom-poms where added (breeding). At the fourth generation, it was shown that the pom-poms that where the color of their mat propered more than the obvious ones did.
