A central theme of human evolution is: |
an increasing adaptive flexibility. |
African Homo erectus cranial features include: |
thick cranial bones |
Based on height calculations of Homo erectus fossils, physical anthropologists estimate that their average height was: |
tall, with males about five feet nine and females about five feet three. |
Compared to australopithecines, Homo habilis is characterized by: |
AOTA: a smaller face, a bigger brain, a rounder and larger skull |
Fossil evidence of cut marks made with stone tools at early hominid sites suggests that: |
meat eating started before Homo erectus but increased with more advanced technology. |
Greater body size and facial gracility documented in Homo erectus are likely related to: |
changes in tool technology and increasing access to meat and other proteins. |
Homo erectus skull morphology includes: |
AOTA:a long, low, wide base. thick bones. large browridges. |
Homo erectus walked just like a modern human, with traits like: |
double arches and adducted big toe. |
Homo erectus’s cranial capacity: |
ranges from 650 cc to 1,200 cc. |
Homo rudolfensis is morphologically similar to: |
Homo habilis. |
Nonhuman primates have smaller brains; therefore the birthing process differs by being: |
shorter and less painful. |
Relative to Oldowan tools, Acheulean stone tools: |
required more learning and skill to produce. |

were gracile. |
The Acheulean complex: |
emerged around 1.8 mya. |

shorter arms and longer legs than those of earlier hominids. |
The original name for Homo erectus was: |
Pithecanthropus |
What are the differences between Homo habilis and Homo erectus? |
Homo erectus shows a reduction in the size of the face relative to the brain case. |
What is the likely explanation for the rapid increase in body and brain size among Homo erectus? |
greater access to protein and improved nutrition |
