The lesson's predation model with moths: each generation the predator eats half the population, then every survivor has one offspring of its own colour · 200 moths
Moths never change colour. Only the proportion of each colour in the population changes.
Grey shading marks generations on dark bark. The % is what to compare, because it is a proportion of the population.
