Darwin did an investigation on finches to observe natural selection aka "survival of the fittest" and he examined how the different sized and shaped beaks effected their survival of retriveing food and worms during periods of drought and during normal periods of weather. The amount of food retreived could also predict the amount of offspring of that certain species of finch. Hope it helps! i did a lab experiment on this.
