|
The Nariokotome Boy discovered at Lake Turkana (Homo erectus) has modern human traits such as: |
shorter arms and longer legs than those of earlier hominids.
|
|
Homo habilis experienced a major shift to new environments that was characterized by: |
tool use for obtaining and processing food.
|
|
What is the likely explanation for the rapid increase in body and brain size among Homo erectus? |
greater access to protein and improved nutrition
|
|
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.
|
|
The discoverer of Homo erectus was: |
Eugène Dubois.
|
|
The controlled use of fire by hominids: |
contributed to geographical expansion and food production techniques in positive ways.
|
|
Which two fossil species lived at the same time around 2.5–1 mya? |
Homo habilis and Homo erectus
|
|
Which species became increasingly specialized to foods requiring heavy chewing? |

|
Relative to Oldowan tools, Acheulean stone tools: |
required more learning and skill to produce.
|
|
Southern and eastern African sites dating to 2.5 mya show habitats indicating: |
a more frequent use of tools for the digging and processing of roots and tubers.

tall, with males about five feet nine and females about five feet three.
|
|
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.
|
|
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.
|
|
The many stone tools, fragmentary animal bones, and teeth found at Gran Dolina, Spain, indicate that hominids there: |

|
|
Eugène Dubois was one of the first evolutionists in the nineteenth century who used the scientific method to test the hypothesis of early human ancestors in Asia with: |
fossil evidence.

in Homo habilis and some australopithecines.
|
|
Modern anatomical features of the Nariokotome Boy include: |
relatively short arms and long legs.
|
|
