Natural Selection --> Evolution

In this class we looked at natural selection and how mutations that are not good for the environment do not survive through the generations.  We did this by using 25 beads each of two colors to show how hairless Bengal tigers got wiped out.  The two green beads represented hairless tigers.  These hairless tigers were put in the killed section because they did not survive in the wild without hair.  After ten generations there was no more possibility for hairless tigers because that mutation was down to one bead which when put with a red one was no different than two red beads.  This shows how a mutation that does not survive the conditions of a creatures environment get wiped out after enough generations pass by.  This is one more point that further proves evolution.  It displays why and how species change over time and eventually evolve with mutations that let them survive, a.k.a.: adaptations.
