Giraffes have adapted to environments where a main food source is leaves of trees. In areas where trees are far taller, the taller giraffes are able to eat and reproduce mor successfully and carry on the gene for greater height, this has continued, giving giraffes long necks which allow the consumption of food sources at greater heights.
Giraffes evovled with long necks so they can reach the tree and eat the leaves.

I LOVE giraffes. There necks don't seem that long to me. They are intelligent
Lamarck would explain the development of giraffes with long necks as a result of the giraffes stretching their necks to reach higher leaves, and passing on this acquired trait to their offspring. This is known as the theory of inheritance of acquired characteristics.
They are born with long necks. Their necks do not "get long". They just are long naturally from birth.
