ANTH 1006 Lecture Notes - Lecture 4: Ardi, Paranthropus, Australopithecus
●Ardi
○Ethiopia : Aramis
○4.4 million years ago
●Ardipithecus Ramidus
○Most complete early homini
○120 cm tall
○110 pounds - 50 kg
○Believe that if you can build one side of the body you can to the other - symmetrical
○Important bones - teeth (dentician) - changes as species become more human like.
■Canines can be used to attack
■You can also tell what they were eating
○Memorize faraming magnum
○Arms are hanging down low - adaptation to arboreal tree living
○Mixture of bipedalism and arborealism
●After 4.4., we see more species that are around africa. (WHOLE LECTURE IN AFRICA)
●Australopithencines
○4.0 - 2.0 mya (million years ago)
○Eastern afrida
○2 important species: afarensis and africanus
○Africanus - resised in south africa like the paranthropus
■Africanus considered to be very small and slim
○If theres a map on the exam, well have to say that australopithecus in the east and the
other one in the south??
○Larger molars - chewing rough material
Document Summary
Believe that if you can build one side of the body you can to the other - symmetrical. Important bones - teeth (dentician) - changes as species become more human like. You can also tell what they were eating. Arms are hanging down low - adaptation to arboreal tree living. After 4. 4. , we see more species that are around africa. (whole lecture in africa) Africanus - resised in south africa like the paranthropus. Africanus considered to be very small and slim. Forehead starts to develop as we move closer to human species. You csn see the set of footprints. Existed for quite some time - adapted quite well to suroundings. Tool use shows some type of change (4-3 mya?) This is cognition - thinking about making and creating things to get more food. Once the tools start to show up - the brain starts to change and grow bigger. This was something that was bult upon.
