Step 1 of 3

Week Nine Anthropology Refresher of Ape Characteristics: I. Adaptations for Brachiation (Swinging in trees): A. Fingers B. Arms C. Shoulders II. Broadening of: A. Ribcage B. Hips C. Sternum III.Loss of a tail IV. Loose Joints I. Miocene Apes: (25 mya - 7 mya) A. During this time there were more species of apes than any other time Examples: I. Proconsulidae - 4 species in East Africa A. Characterized by 1. More Monkey like 2. Surprisingly not very ape like characteristics a) Still thought to be more closely related to apes than monkeys b) Teeth ARE ape like (1) Ape teeth are PRIMITIVE though c) No tail d) Loose joints 1 of 1 Week Nine 3. Proconsulidae were at end of olgocene - beginning of Miocene II. Oreopithecidae A. Oreopithecus 1. Lived 20 mya in Europe 2. Lived in Swampy Lands 3. Believed to be bipedal a) Belief is based on: (1) pelvis and feet fossils b) Swamp waters could have helped in bipedalism (1) Present day apes can use water to take weight off hind limbs and can walk bipedally for a short time III. Pongidae A. Present Day Orangutans are in this family B. Sivapithecus 1. Lived in the Late Miocene in Europe and Asia 2. Skull and teeth are similar to orangutans a) From neck up it is similar to orangutans b) From neck down it is not similar C. Gigantopithecus 1.

Thus the name GIGANTOpithecus. a) Speculated to be around 800 pounds D. Lufenpithecus 1. More likeOrangutans that sivapithecus 2 of 1 Week Nine IV. Hominidae A. Dryopithecus 1. Lived 12 -9 mya in France and Spain 2. Characterized by: a) Long arms, fingers, and hands b) Teeth are African Ape like (1) Probable diet of fruit and leaves B. Ouranopithecus 1. Lived 9 mya in Greece 2. Face is African Ape like C. Nakalipihecus 1. Lived 9.9 mya in Kenya 2. Teeth are African Ape like a) Most likely ate tough foods Terrestrial 3. a) Based on teeth wear 4. Only teeth/jaw were found D. Choropithecus 1. Lived in Middle Miocene in Ethiopia 2. Only teeth (no jaw) were found 3. Gorilla like teeth 3 of 1 Week Nine Epoch Years Paleocene 65 - 55 million years Plesiadapiforms (Primates) Eocene 55 - 34 million years Omomyoids (Haplorihines) Adapoids ( Strepsirrhines) Athropoids Oligocene 34 - 23 million years New World Monkeys Miocene 23 - 9 million years Apes - Hominoids Derived Traits of Humans found in Fossils: 1. Bipedalism 2. Precision Grip in hands 3. Enlarged Brain 4. Development of Language 5. Ability to manipulate nature (tool making) 6. Dental Changes • It is thought that chimpanzees and humans split around 7 million years ago I. Sahelanthropus tchadensis A. Lived 7-6 mya in Chad in the Djurab Desert B. Derived Traits: 1. Small and worn canines 2. thickness of enamel greater than chimpanzees a) Not as thick as human enamel 3. Anterior Foramen Magnum a) As opposed to Posterior found in other apes 4 of 1 Week Nine 4. Flat face (orthognathism) C. Primitive Traits: 1. Small brain and brain case 2. U - shape dental arcade a) as opposed to Parabolic shape found in humans 3. Shape of skull base a) Similar to that of a gorilla II. Orrorin tugenesis A. Lived 1.6 mya in Tugan Hills, Kenya B. Dentition traits: 1. Thick Enamel (a derived trait) 2. Large Canine (a primitive trait) 3. Molars that are human like C. Post Cranium (below the head): Femur traits: 1. a) Large head (a derived trait) b) Angled neck (a derived trait) c) Thick neck (a derived trait) (1) The femur is made of two kinds of bone: (a) Inner bone is made up of spongy bone (b) Outer bone is made up of compact bone (2) The distribution of the bone can aid in determining if something is bipedal 5 of 1 Week Nine (a)Primates (excluding humans) have even distribution of spongy bone. It looks like this: (b) Humans is not evenly distributed and looks more like this: The second image is that of a bipedal human. The spongy bone is distributed unevenly due to the weight of walking bipedally instead of walking quadruped ally III. Australopiths (Australopithecina) There are 12 species in 4 different genera A. 1. Ardipithecus 2. Australopithecus 3. Paranthropus 4. Kenyanthropus B. Lived 5.8 -1.0 mya in South Africa and East Africa C. Post Cranial: 6 of 1 Week Nine 1. Evidence for bipedalism in hind limbs 2. Evidence for Tree Dwelling in forelimbs D. Skull/Cranium 1. Brain size is small compared to humans a) about 1/3 -1/4 the size of a humans I. Ardipithecus A. Ardipithecus ramidus: 1. Lived 4.4 mya (early Pliocene) in Aramis, Ethiopia a) ‘Ardi’ is the most complete fossil set found so far. (1) Believed to be a young female adult (2) Having: (a) Cranial capacity of 350 cc (a primitive trait) (b) Small face (c) Narrow incisors Reduced Canines (a derived trait) (d) i) Canine size is a sexually dimorphic trait (1) Male canines are bigger than those of females (e) Forward foramen magnum (a derived trait) (f) Broad pelvis ( a derived trait) i) Top part of pelvis is human like being broad, but bottom is primitive being more narrow and tall (g) Bipedal femur (a derived trait) (h) Unspecialized forelimb (a primitive trait) (i) divergent big toe (a primitive trait) 7 of 1 Week Nine B. Ardipithecus kadabba: 1. Lived 5.2 -5.8 may in Middle Awash, Ethiopia 2. Dentition a) Primitive Traits: (1) Thin Enamel on teeth (2) Honing premolar b) Derived Traits: (1) Even thickness of enamel (2) Large canine teeth 3. Post cranium: a) Homo like elbow and wrists (a primitive trait) b) Fingers are long and curved II. Australopithecus A. 3 species in East Africa (Ethiopia, Kenya, and Tanzania) Could be more or less species of 1. A. anamensis Australopithecus given more recent a) Lived 4.2-3.9 mya in East Africa (Allia Bay and discovers. Kanapoi) Many of the b) Primitive Traits Australopithecus Large is (1) Dental: have similar a combinations of relative (a) large canines primitive and derived term. traits. (b) Sectoral Premolars i) Where the canine overlaps on the other row of teeth (2) Post Cranial: (a) Long arms c) Derived Traits (1) The tibia is large, flat, and lateral condyle (end of bone) 8 of 1 Week Nine (a) This is a good indicator of bipedalism (2) Thick enamel (a) More human like (3) Elbows and wrists like that of a human (a) Not actually derived (b) ‘lightly built’ unlike those used for knuckle walking 2. A. afarensis a) lived 4.0-2.9 mya in East Africa (Hadar, Ethiopia; Laetoli, Tanzania; Koobi Fora, Kenya) Famous Example: b) (1) Lucy c) Brain size: (1) On average 438 cc (a) About the same size as modern chimpanzees i) About the same physical body size too d) Primitive Traits: (1) Large canine (2) Parallel tooth rows (3) Long arms (a) Lived in trees (aka arboreal) e) Derived/ Human-like traits (1) Thick enamel on teeth (2) Bipedalism (a) Adaptations in the feet, pelvis, and leg Foot was not as efficient as the human foot i) 9 of 1 Week Nine ii) The big toe was diverged, but not as diverged as other Australopithecus 3. A. garhi a) lived 2.5 mya in Middle Awash, Ethiopia b) Very few bones found of A. garhi c) Primitive traits: (1) Long, chimp like arms (2) Large canines (3) Projecting, or prognathic, face Derived/ Human-Like traits: d) (1) Very large teeth (2) Long legs (3) Possible tool use B. 1 species in Central Africa (Chad) 1. A. bahrelghazali a) Lived 3.5-3.0 mya in Bahr-e-lghazai, Chad b) It is virtually identical to afarensis (1) It has a different name due to the distance between the two. C. 2 species in South Africa 1. A. africanus a) Lived 3.8-2.8 mya in South Africa (Taung; Sterkfontein; Makapansgat) b) Brain size is, on average, 450 cc c) FULLY bipedal d) ‘Little Foot’ a set of fossils found of A. africanus (1) (a) though it is bipedal it has a slightly divergent big toe 10 of 1 Week Nine 2. A. sediba a) Lived 2.0-1.8 mya in the Malapa Caves in South Africa b) Derived / Homo like traits: (1) Cranial: (a) Temporal lines are widely spaced (b) slight postorbital constriction (2) Post Cranial: (a) Reduction in weight transfer (b) Expanded (wider) illium III. Paranthropus (robust Australopiths) A. P.aethiopicus 1. Lived 2.7-2.3 mya in East Africa (West Turkana; Omo) 2. Brain size: a) Relatively small - 410 cc Prognathic face 3. 4.
