The study is focused on the evolution of the Littorina obtusata‚ also commonly known as the Flat Periwinkle Snail. This experiment focuses on Littorina Obtusata snails due to their evolution in shell thickness and shell shape. The purpose of the experiment is to understand the process of evolution and natural selection on organisms and why they occur; understanding the importance. By doing the experiment I hope to explore the effects of predation on a population‚ how predation influences evolution
