More info: Hamadryas baboons are what are known as Old World monkeys meaning they belong to a group of monkeys found in Africa and Asia whereas New World monkeys are found in the tropics of Central and South America.
There are physical differences between Old and New World monkeys. Hamadryas baboons have classic Old World monkey characteristics like non-grasping (or prehensile) tails, they are primarily terrestrial, and they have opposable thumbs that are very similar to a human's thumb. These traits are rarely seen in New World monkeys. Hamadryas baboons display complex social behaviours, and can live in troops of several hundred individuals. They are found in the wild in large populations in Ethiopia, Somalia, Saudi Arabia, and Yemen. In fact, no other species of baboon resides as far north as hamadryas baboons.

Gelada monkeys are found only in the highlands of Ethiopia and Eritrea and are the world's most terrestrial primates - except for humans. Gelada monkeys are terrestrial, or ground dwellers rather than tree dwellers and they prefer to sleep on rocky cliffs at night. They are very adept climbers and the higher elevation provides less threat from predators. They will descend in the mornings to go foraging - Geladas are grass eaters and as such are the last surviving species of ancient grazing primates that were once numerous. Gelada monkeys have impressive canine teeth — especially the males, who rely on their fearsome fangs not to eat but to signal dominance or to fight.
