Giraffes use their extremely long necks to reach the leaves high up on acacia trees, which other animals cannot reach, giving them a food source for which they have few competitors. What can you conclude about natural selection from this observation Giraffe necks get longer over a lifetime of stretching, and their offspring inherit the longer necks of their parents.

The giraffes with the longest necks survive and produce offspring
