Models always have limited parameters and constraints. Models typically simplify a complex system into variables that can be controlled.
In this case, we were trying to see what variables increased moth survival based on their color, camouflage, and predation.
What are some variables in the peppered moth simulation that were not addressed?

Other variables that could have been taken into account are size, variability of shape in its wings and degree of darkening in its wings.

Explanation:

Of the three named variables, I believe that the degree of darkening is the most important since in this way we can realize the association of its color with environmental pollution, and thus be able to look for a cause-effect relationship.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
