Exam 11: The Origins and Evolution of Early Homo
Describe Homo erectus's cranial and postcranial anatomical characteristics.How is this species significantly different from earlier hominids?
Homo erectus is characterized by increasing cranial capacity and a gracilization of the face,jaws,and teeth.It is also marked by increased body size and the first evidence of modern human limb proportions.The fossil evidence indicates a rapid increase in body size about 2.0-1.7 mya.Greater body size and facial gracility likely relate to changes in tool technology and greater access to meat and other proteins.Growth patterns (as indicated by analysis of perikymata on the Nariokotome Boy's teeth)are thought to be slower than earlier hominids' but not as slow as modern humans'.Overall,H.erectus represents a real departure from the smaller-brained,larger-faced australopithecines,who had a more mixed arboreal/bipedal pattern of locomotion and used stone tools less often,if at all.
Analysis of Homo erectus teeth found at Zhoukoudian suggests that controlled use of fire allowed this species to:
C
Evidence from the Nariokotome Boy suggests that modern human growth patterns were already present in Homo erectus.
The many stone tools,fragmentary animal bones,and teeth found at Gran Dolina,Spain,indicate that hominids there:
