were more abundant in these grasslands. This means that natural selection acted on the shell colour, which means that shell colour is the interactor in this example. Furthermore, they found that the brown individuals were more abundant and had a higher survival rate in woodlands than the yellow individuals. Moreover, a specific form of natural selection called thermal selection showed that shell colour worked in the interaction with the environment by yellow shells being more abundant, so more adjusted to reflect heat, in warmer places.

One of the conclusions that could be drawn out of this research is that in grasslands, yellow individuals had a higher survival rate and

there is often variation in heritable traits among individuals, in which a form of the trait might be more beneficial than the other form(s). Due to this difference, the chance of getting more adjusted offspring to the environment is higher. The process describing the selection of the environment on

Vehicles are often used as a synonym of interactors, only in a way that vehicles can "drive" natural selection, as if they have the behaviour to steer natural selection in a specific way. The term "vehicle" makes it look that way and therefore some people (like
