Document Summary
Referential modelling use one species to think about second species. Using chimpanzees for thinking of fossil hominins. Synchronic study (looking at the relationships among things at the same time) vs diachronic study (tracking the same entity at different times or through time) Slide 3 - australopithecus (middle) resembles chimp in long arms and cranium but below pelvis resembles humans. If we were to theorize on australopithecus based off chimpanzee we would be really reaching. In miocene, lots of ape species all over world (asia, africa etc) Slide 4 - e. g. thought this one species of ape in miocene were two distinct species when really they just showed really heavy sexual dimorphism. Slide 5- some of the lemurs appeared like sloths while others more like koalas (megaladapis) We don"t have another species to infer on the locomotion of these extinct species. Pelvis is really good indication of sex. Men has slightly more pronounced brow ridge.
