Document Summary
Biggest reason is that it may be the first hominin who uses stone tools (modifying material with intention) Profound in terms of our evolutionary history. Primitive traits: prognathic face (meaning protruding jaw, jaw that juts out), gorilla sized brain, sagittal crest. Primitive traits are those inherited from distant ancestors. Derived traits are those that just appeared (by mutation) in the most recent ancestor -- the one that gave rise to a newly formed branch. Of course, what"s primitive or derived is relative to what branch an organism is on. The oldowan (or mode i) is the earliest widespread stone tool archaeological industry in prehistory (it is pre-dated by lomekwian tools at a single site dated to 3. 3 mya (million years ago). [1] oldowan tools were used during the lower paleolithic period, 2. 6 million years ago up until 1. 7 million years ago, by ancient hominids across much of africa, south asia, the middle east and europe.
