The scenario described is an example of Directional Selection. This is because the average height of the giraffe population is increasing in response to environmental pressures (trees with fewer leaves on lower branches), favoring taller individuals who can reach food higher up. This leads to a shift in the population toward greater height over generations.
Question While all giraffes are tall they are not all the exact same height. Within a population, the height of each individual giraffe can vary. Scientists observe that over many generations the average height of the giraffe population is increasing. They believe this in response to trees producing fewer leaves on lower branches, meaning the giraffes' main food source is higher up. What kind of selection is this an example of?
