Giraffes have shorter necks before, but because of the news to survive and in order to reach tall trees for food,they kept stretching their necks until these became longer and able to reach taller trees​

Explanation:

Since these shorter creatures pick over food at a lower level, giraffes' necks allow them to reach food and nutrients that others cannot. This becomes especially important for survival in habitats where food can become scarce and droughts are fairly common
