Answer

The short answer is that one way or another, having a long neck became an advantage for survival.

Beyond that, opinions differ. The old theory stated that the long necks allowed giraffes to eat leaves out of reach from other animals. Less competition about food can be a survival advantage.

As explanations goes, this has some weaknesses. There are plenty of other animals living alongside giraffes that seems to be doing just fine w/o reaching that high.

A newer theory is that it's more about breeding rights. Male giraffes fight by standing close to each other and swing their heads into each other. Here, a longer neck is a definite fighting advantage, and you get the elevated grazing as a side effect.

Answer

So it can reach the trees and vegetation that in the giraffe's native home is usually growing taller to allow for air movement underneath the plant to help with the temp.

Answer

Giraffes have a long neck as there is much competition for food and by having long necks, they can reach higher branches that other animals cannot get to.

Answer

Long necks are an evolutionary change which has happened to giraffes over a long period of time.

They have long necks is because giraffes love green juicy leaves but the juicy leaves are at the very top where none of the other animals can reach. The giraffes have to reach to the top to get the juicy leaves that is why their long necks help them eat.
