Photo slideshow of various primates I've worked with at a wild animal park (except the orangutans and gorillas, which were photographed elsewhere). • • Humans belong to the taxonomic Order Primates, which is comprised of 11 Families, 52 Genera, 181 species. Primates are divided into two main groups: Prosimians (literally before monkeys/apes) and Anthropoids (literally man like ). The evolution of primates is characterized by trends toward mobile limbs, grasping hands, a flattened face, binocular vision, a large, complex brain, a reduced reproductive rate. Most Primates are well adapted to arboreal living (living in trees). • • Primate evolution occurred primarily during the Cenozoic Era, Prosimians first branching off in the early Eocene Epoch 58 mya (million years ago). • • Around 33 mya, during the Oligocene Epoch, the Anthropoids split off into 3 main groups: New World Monkeys (w/prehensile tails), Old World Monkeys (w/out prehensile tails), the Hominoids (eventual Apes Humans w/out any tails). • • In the Miocene Epoch, around 15 mya, Asian Apes African Apes diverged paths. At approx. 6 mya, African Apes Human lineage split, producing Hominids (members of the taxonomic Human Family Hominidae) in a region of Central Africa called the Great Rift Valley. There, dense jungle gave way to great savannah plains, bipedalism became a helpful adaptation in surviving in a high grass environment w/a variety of predators. • • To this day, Chimpanzees Humans share 98.5% of the same DNA sequences, even though millions of years separate us from a common ancestor. The evidence for evolution has been found within the fossil record. Additional corroboration has been found comparing DNA sequences which show dramatic linkages between all modern primate species. A comparative study of mitochondrial DNA shows that the differences among present human populations are consistent w/their having a common ancestor no more than a million years ago. • • Prosimian (lemurs, tarsiers, bushbabies lorises) • 0:26-0:45 Ring Tailed Lemur • • Anthropoids (monkeys, apes humans) • • New World Monkeys (w/prehensile tails) • 0:52-1:02 Black Tamarin Marmoset • 1:03-1:10 Squirrel Monkey • 1:11-1:18 Capuchin Monkey • 1:19-1:26 Woolly Monkey • 1:27-2:10 Spider Monkey • **1:47-1:51 a spider monkey is investigating/ harassing a river turtle. • **1:52-1:57 two spider monkeys are investigating/ harassing an alligator. • • Old World Monkeys (w/out prehensile tails) • 2:13-2:36 Vervet Monkey aka Green Monkey or Guenon or Grivet • **These are the monkeys scientists have thus far linked as a carrier species for the RNA retrovirus associated w/HIV/AIDS. • 2:37-3:43 Rhesus Macaque • **3:13-3:43 show a troop of rhesus macaques interacting w/Sika Fallow deer, as well as Mouflon sheep raccoons. • • Hominoids (apes humans, w/out any tail) • • Asian Apes • 3:45-3:53 White Handed Gibbon • 3:54-4:08 Orangutan • • African Apes • 4:11-4:32 Lowland Gorilla • 4:33-4:59 Chimpanzee • • Human • 4:52-4:59 Me kissing a Chimpanzee ^_^ • • • All photographs are the property of Dafttool cannot be reproduced or used without the expressed authorization of Dafttool.
