A Penn State researcher has been trying to get to the bottom of the age-old question of why giraffes have long necks. Focus on research: Female giraffes drove the evolution of long necks, new ...
Thus, these nerve cells have a length of nearly 5 m (16 ft) in the largest giraffes. [78] Despite its long neck and large skull, the brain of the giraffe is typical for an ungulate. [80] Evaporative heat loss in the nasal passages keep the giraffe's brain cool. [54] The shape of the skeleton gives the giraffe a small lung volume relative to its ...

The okapi's neck is long compared to most ruminants, but not nearly so long as the giraffe's. Male giraffes are the tallest of all mammals: their horns reach 5.5 m (18 ft) above the ground and their shoulder 3.3 m (11 ft), whereas the okapi has a shoulder height of 1.7 m (5 ft 7 in). [9]
Giraffes gain their long necks by a different heterochrony, extending the development of their cervical vertebrae; they retain the usual mammalian number of these vertebrae, seven. [1] This number appears to be constrained by the use of neck somites to form the mammalian diaphragm muscle; the result is that the embryonic neck is divided into ...
The long neck is a result of mating. Male giraffes fight over females by wrapping their necks around eachother. The one with the longer neck usually has more force and wins the right to breed with the female. As a result the gene for the long neck increases within the population because it increases the giraffes chances for breeding.
