The body mass of individual beetles of a certain species ranges from 0.8 grams to 2.9 grams. A population of birds is able to catch beetles having a mass of 1.8 to 2.2 grams. The birds removed a majority of these beetles and the population changed. After 300 generations, the individual mass of beetles in the population ranged from 0.8 to 1.4 grams and 2.4 to 2.9 grams.
