Refer to the figure.
This figure is based on data from a study of how ambient temperature during development affects adult body size. The figure shows data for individuals of a single genotype in a single species. A total of 20 individuals were raised under different temperature treatments.
-The blue bars show the average body size of individuals for each temperature treatment, and the black bars provide a measure of the variation in body size recorded for each treatment. Suppose that this species is an animal. In this animal species, larger individuals have a much higher reproductive output, but smaller individuals are better at surviving unpredictable weather (especially colder temperatures). Over a long time scale, how might the average size of individuals of this species be affected by the predictability of average temperatures?
