-lots of raw material brought in but just left there, about a half ton brought in from about 50 km away -suggests they were preparing for something in the future and that this was a shared vision, lots of people felt this way -layers: .9 mya occupational debris and skulls, .7 mya ash fall, .6 mya cobble “storage”, modern surface Ratio of animal bones to stone tools at Olduvai gorge -many more tools than bones at Acheulean sites, opposite at Oldowan sites Things Mode II doesn’t tell us -mode II doesn’t always replace mode I, do the tools reflect intellectual/functional differences or cultural/tribal differences? -mode II shows minimum intellect of the maker, not the maximum Control of fire -humans were probably already familiar with natural fire -around 1.4 mya we see two sites with evidence of localized burn areas and cutmarked bones, processed bones within a burned area -Chewsowanja in Kenya is an example, we see what looks like a hearth and cutmarked bones -Swartkrans is another example Advantages of fire -defense and protection -used to drive large areas into an area where they could be killed -provides light, extends the day -provides a focus for activities Europe information -Ceptrano, Italy: .8 mya erectus -Isernia la Pineta, Italy: .7 mya: Home base site: mode 1 tools, a buchery site -Atapuerca, Spain: 1.4 mya-.3 mya: H. antecessor, H. heidelbergensis Atapuerca, Spain -lower level remains show a species called H. antecessor -pieces have been shattered and there aren’t very many details -antecessor shows less prognathism than erectus, has a hint of a chin (shows that the jaw is getting smaller) -antecessor bones are cannibalized, cutmarks on the bones made by stone tools, they are broken up into small pieces -this shows a kind of cannibalism that comes from when an enemy is conquered (exocannibalism) Cenozoic climate changes -in the late Cenozoic, there were many back and forth trends of warming and cooling -major human entry was the first interglacial between the first and second ice ages
