est Africa. Its diet is composed of leaves. This diet has caused the evolution of a leaf-digesting organ. It is situated in the same place as a human appendix. At the time of birth they are white colored creatures, but within six months they get adult coloration. Most of their time is spent in treetops. Locomotion is quadrupedal and they are considered to be one of the most spectacular leapers. Now we come to the remaining three epochs, the Miocene (25 m.y.a.), Pliocene (5 m.y.a.) and Pleistocene (1.8 m.y.a.). These eras marked the first appearance of modern primates, including man. At the time of the Miocene appeared the Gorilla. It first appeared in the tropical forests of West Africa. The diet of a gorilla consists of fruits, vegetation and insects such as termites and ants. Gorillas are the largest of the living primates the male weighs up to 475 pounds and the female weighs up to 250 pounds. The leader of a group of gorillas is called the silver back as it has gray hair on its back. They have the ability to walk on two extremities but generally they walk using all fours. But, it is enough proof that as time has gone on the primate has become more and more erect. This has enabled them to adjust easily to the perils of terrestrial life. They can use there fore limbs to hold things and thus making them similar to humans. All though gorillas have been given the reputation of being ferocious killers, they are very shy and harmless animals. As I watched them in the zoo, they seemed very harmless. Most of them just sat on the rocks and were acting as if there was no one watching them.The Orangutan comes from the tropical forests of Borneo and Sumatra. They are different from other apes as they are more solitary animals. They eat fruit, leaves, eggs, and bark. They are knuckle-walkers and tend to have social gestures towards each other by grooming each other. Their hair length is longer, skin coloration is almost transparent, and thei...
