Did giraffes evolve their long necks for combat? 
Giraffes are widely thought to have evolved such long necks in order to feed 
on high foliage that other animals found difficult to reach. But it may actually have 
been competition for mates that gave them this unique adaptation, researchers at the 
Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy 
of Sciences have found.
Giraffes’ necks can measure two to three meters in length. During courtship 
competitions, the animals fight by using their long necks to whip their heavy skulls, 
which are topped with hard, horn-like ossicones, into their opponents.
Animals with longer necks are able to land more powerful blows on their 
opponents, making them more likely to win fights for mates. It is also believed 
giraffes with longer necks are deemed to be further up the social hierarchy. Now, a 
17-million-year-old fossil of Discokeryx Xie Zhi, an ancient relative of modern 
giraffes, found in Junggar Basin, Xinjiang, western China, suggests that this 
behaviour may be what led to the animals evolving their trademark long necks. 
Though its neck is much shorter than that of modern giraffes, analysis of the fossil 
shows that D. Xie Zhi had an incredibly complex series of joints between its head 
and spine, along with a hard, disc-shaped ossicone on its head that made it
