A population of Rothschild’s giraffe lives in the woodlands of Uganda with trees of varying heights. Following a flood in the area, all shorter plants were uprooted but taller trees survived the flood. After several generations, it is observed that the giraffes inhabiting the woodlands have longer necks than the giraffes living in the same area prior to the flood. Which of the following evolutionary phenomenon has occurred in Rothschild’s giraffes?
1. Extreme selection
2. Stabilizing selection
3. Disruptive selection
4. Directional selection
