 * __Hypothesis__**

Polymorphism of //Capaea nemoralis// in various habitats is due to natural selection.
Snails are more preferable to study because in their lifetime they only move up to approximately 30 meters, than compared to humans, which have a greater ability to travel and have a much greater spread across the planet. Therefore to identify the effects of natural selection and genetic drift within a population, snails will be our organism of choice.
 * __Introduction__**

Using quadrates over 6 different locations in two different types of habitat and altitudes we will observe the varied phenotypes within the //Capaea nemoralis// population. This should demonstrate how polymorphism is due to natural selection as the selection pressures at the different altitudes and habitats would be different and this should be observable. We are studying two different habitats at two different altitudes. We are controlling the effects of other variables on our sample. We are only taking 1 sample from the scrub in each altitude. Also we are not taking any samples from the woodland area. We are not measuring temperature.
