Natural Selection Lab Report Natural selection relies upon the assumption that all organisms produce more offspring than can survive in an environment demonstration limited resources. In this lab‚ we are trying to see which prey (beans) would survive and which predators (students with different type of mouthpart) would survive. I think green bean would survive because it is very tiny. The predator use hand as mouthpart would survive. To start the lab‚ we need seven different beans together
