Organizing and summarizing search results for youThe evolution of giraffes is believed to have occurred in southern central Europe about 8 million years ago. Their proximate ancestors likely arose from the gelocid ancestral assemblage via the family Palaeomerycidae. Charles Darwin's theory of how the giraffe got its long neck suggests that slight, successive changes over time gave the giraffe a competitive advantage for reaching tree-top leaves.2 Sources

Giraffe - Wikipedia
The giraffe is one of only two living genera of the family Giraffidae in the order Artiodactyla, the other being the okapi. They are ruminants of the clade Pecora, along with Antilocapridae (pronghorns), Cervidae (deer), Bovidae (cattle, antelope, goats and sheep) and Moschidae (musk deer).
