Document Summary
15 mya: split of evolutionary line with the gibbons. Discovered in 2004, lived in spain, ate fruits and seeds. Tree climber (flat rib cage, stiff lower spine, flexible wrists, flat shoulder blades). Side note on climate: pre-15 million years ago. Warm and wet (wetlands and tropical forests: after 15 million years ago. Drought: after 7 million years ago. Cold: climate is ours" by 5 million years ago, homonid paradigm shift: bipedalism = 3. 5 mya. Like a human: reduced molars and canines, like an ape: Grew rapidly after birth and reached maturity much more quickly than humans. This means that there was less time for parenting and culture development. Ate leaves, fruits, seeds, roots, nuts and insects but not big animals. It is also thought that the earliest tools were made by australopithecus because they dominated at the time when tools first start to appear in the record .
