Slide 2

Geologic Time & Human Evolution

Slide 3

The Eocene age (55-35 mya) Eocene hottest age of Cenozoic NW Tenn., trop. rain timberland, similar to Panama First appearance of numerous advanced requests of vertebrates As specified, rodents First bats, whales, present day ungulates and carnivores Most imperative for us, the main P.O.M.A. Primates of Modern Aspect Two noteworthy gatherings: the adapids and omomyids Both gatherings and no more primitive review of adjustment

Slide 4

The Adapids First show up in early Eocene (50-55 mya) Possibly in Asia in late Eocene Found in both Europe and N. America Early structures increasingly various in Europe Three imperative genera: Cantius - soonest adapid Only early Eocene sort from N. Am. & Eur. Adapis - lemur-sized European shape Named & portrayed by Cuvier (1821) Notharctus - lemur-sized American frame Very lemur like

Slide 5

The Omomyids First show up in early Eocene (50-55 mya) Found in Europe, N. America and Asia Early structures progressively various in N. America Important genera: Teilhardina - most punctual omomyid From Belgium Rooneyia - from late Eocene of N. America they were exceptionally Tarsier or galago like

Slide 6

Adapids versus Omomyids

Slide 7

The central issue: Which aggregate offered ascend to the Anthropoids (Human and Great Ape Line)? Most fossil elements indicate the adapids Omomyids are great precursors for tarsiers

Slide 8

The Oligocene age (35-25 mya) - the primary Anthropoids The Fayum dejection - Egypt, 60 mi. SW of Cairo Early Oligocene (ca. 33 mya) 2 genera: Apidium - squirrel-sized arboreal quadruped Dental recipe: 2-1-3-3 Could be precursor to both N.W. also, O.W. Aegyptopithecus - most vital of Fayum discovers Dental recipe: 2-1-2-3 moderately huge mind Large bodied, ~12 lbs. by and large Substantial canine sexual dimorphism Heavily-built, arboreal quadruped

Slide 9

Aegyptopithecus

Slide 10

Aegyptopithecus Reconstruction

Slide 11

Old and New World Monkeys Aegyptopithecus is best contender for hereditary Old World Monkeys Adaptation: like cutting edge monkeys What about the New World Monkeys? Soonest fossil confirmation from Bolivian Oligocene Geologically same time as Fayum, ~33 mya

Slide 12

Miocene Primate Evolution The Miocene age (25-5 mya) - "The Golden Age of Apes" Two noteworthy hominoid radiations The dryopiths - Early to Middle Miocene (25-15 mya) The ramapiths - Middle to Late Miocene (15-5 mya)

Slide 13

The Dryopiths Distribution (geographic and worldly) Most structures from E. Africa Some Mid-Miocene frames from Europe Important genera Proconsul - Early Miocene, E. Africa Dryopithecus - Mid-Miocene, W. Europe Morphology Cranial elements Generalized No significant biting specializations Post-cranial ("below the head") highlights Body measure: monkey to _ gorilla-sized Limb extents - monkey-like Fore-appendages not prolong moderately short fingers & toes

Slide 14

Dryopithecus

Slide 15

Dryopithecines Reconstruction

Slide 16

The Ramapiths Distribution (geographic and fleeting) Most across the board hominoids ever (until us) Turkey, Hungary, Greece, Pakistan (14-8 mya) Later in China and terrain SE Asia (~8-0.5 mya) Ancestors? Likely a Middle Miocene, E. African frame Kenyapithecus : a decent progenitor, ~14 mya enormous capable jaws thick molar lacquer Most imperative variety Sivapithecus (incorporates Ramapithecus )

Slide 17

General Ramapith Morphology Dentition like Dryopiths One noteworthy dental character is thick molar finish Cranial components More primate like, biting specializations Post-cranial elements Not much proof; apparently more chimp like More portable shoulder joint Possibly more earthly than Dryopiths

Slide 18

Specific Sivapithecus Morphology "What awesome gorilla would it resemble?" Later Asian structures Cranial elements reflect Orangutan Sloping lower confront/jaw It\'s best translated as precursor of Pongo (Orangutan)

Slide 19

Sivapithecus

Slide 20

One other intriguing ramapith family: Gigantopithecus Found in Pakistan and China Dates to 9-0.5 mya, most recent surviving Ramapith Huge jaws and teeth; just parts found May have been 6-9 ft. tall, >600 lbs! What brought about its annihilation? Possibly early people More everyday: Giant Panda Same specialty, extensive bodied bamboo eater Maybe NOT wiped out! Accursed Snowman & Sasquatch ???

Slide 21

Gigantopithecus

Slide 22

Last Common Ancestor? Not able to decide correct example so far. Atomic information proposes split happened somewhere around 6 and 5 million years prior. Broad hereditary differing qualities in hominoids amid the Miocene.
