Homo erectus is usually found with oldowan like mode

This preview shows page 5 - 8 out of 9 pages.

- Homo erectus is usually found with Oldowan-like mode 1 tools - so maybe it was not capable of making mode 2 tools - if so, maybe the lineage of H. erectus split from early H. ergaster before that species had made whatever mental leap allowed them to make mode 2 tools - if so, that would imply that the ability to make mode 2 tools involved a fairly distinct step up in cognitive abilities, which only happened in the lineage of H. ergaster - but maybe H. erectus could make stone mode 2 tools, but just did not need to - they had plenty of bamboo, which easily splits into good, lightweight cutting tools - Exception: mode 2 handaxes were recently found in the Bose basin of southern China

Intro to Biological Anthro F 2011 / Owen: Homo but not quite us p. 6 - around 0.8 mya, a large meteor strike burned the forests off the region and exposed good toolmaking stone that would have previously been covered by soil and vegetation - Acheulean-like mode 2 tools appear only in this region and at this time - maybe made by H. erectus - when faced with the need (scarcity of bamboo?) - and the opportunity (availability of appropriate stone) - or maybe made by bigger-brained H. heidelbergensis , - which had just appeared in Africa and Europe at this time, - and we know was present in Asia later - Homo erectus could handle cold - Zhoukoudian cave, northern China, near Beijing - occupied 0. 5 to 0.25 mya - snow-covered winters today, and even more so then, during the Pleistocene ice ages - does the ability to live at Zhoukoudian imply that H. erectus controlled fire? - does Zhoukoudian imply that H. erectus hunted game? - in winter, game may have been the only food available, suggesting that they hunted - the cave is full of bones, mostly from just two species of deer - clearly hunted by something: maybe H. erectus ? - would any hunters other than hominins have been so selective? - but the cave also contains hyena bones and hyena feces - and the H. erectus crania found there are badly damaged, with their faces and the bases of the crania often broken off - so did H. erectus hunt the deer and the hyenas? - or did the hyenas hunt the deer and the H. erectus ? - Homo ergaster was clearly our ancestor; H. erectus was evidently not - Homo ergaster apparently evolved into Homo heidelbergensis - appearing somewhere between 0.8 and 0.5 mya (800,000 – 500,000 years ago) - and persisting until about 0.2 mya - until recently, often just called “archaic Homo sapiens - Some features of Homo heidelbergensis - Derived features that resemble modern humans - bigger brains, around 1200-1300 cc - modern humans range from about 1000 to 2000 cc, averaging around 1400 - so we are getting into the range in which raw brain size does not tell us much about the differences between these creatures and us - higher, rounder braincase than H. ergaster - Ancestral features - still have thick cranial bones - cranial shape still longer and lower than modern humans - massive browridges - heavy, projecting, relatively prognathic face compared to us - no chin (that is, receding chin)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
