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.
They do not have short necks. They have very long necks. compared to their body size they have short necks because when they try to drink water they have to spread out their legs to reach water so they could be attacked and if they were they would be very vulnerable.
