Sticks used in friction to heat and burn other flammable materials. c. Stones arranged in a traditional fire hearth placement. d. Rock art depicting flames and fires.
Answer: a Feedback: Evidence of fire comes from a variety of sources, including remnants of the fire itself, such as charred wood or ash, as well as things that have been heated, including bone, stone, and clay.See page 102.
36. Which is the correct order of the following weapons, listed chronologically oldest to youngest, in the archaeological record? a. Acheulean handax, spears, atlatl b. Atlatl, Acheulean handax, spears c. Spears, Atlatl, Acheulean handax d. Atlatl, spears, Acheulean handax
a. Acheulean handax, spears, atlatl
until 10,000
human groups were fairly mobile
habitation site
inference that people were living at the site, at least on temporary basis
Evidence of group were
mostly egalitarian by fairly equitable distribution of resources within habitation site
Problem for archaeologists include determining whether the remnants of fire they observe are
natural or cultural
Palaeolithic means
old stone ages
archaeologists are interested in ecofacts for two main reason
palaeoenvironments diet
middle palaeolithic is equated with
people and cultures associated with archaic homo sapiens, homo heidelbergensis, and neandertals
lower palaeolithic describe
people and cultures associated with homo habilis and homo erectus(lumper view)
ecofact
plant and animal remains
Acheulean
tool associated with homo erectus and bifacial(flake taken of both side)
Some anthropologists believe human started controlling fire almost
two million years ago
Ideology is difficult to study in the archaeological record because a. archaeologists prefer to work with skeletal remains. b. it is nearly impossible to receive grant funding to study ideological aspects of early culture. c. it is an intangible thing reliant upon archaeologists' interpretations. d. out of all the early human groups, only modern Homo sapiens were advanced enough to engage with ideologies
.Answer: c Feedback: Art, religion, and anything intangible stemming from ideology requires some kind of physical remains (such as burial rites, cave art, etc.); these things are therefore even more susceptible to interpretation biases.
The majority of archaeological sites concerning early humans have been found a. in Europe, due to overrepresentation and Eurocentric attitudes within the discipline. b. in Africa, since this is the birthplace of modern human life and culture. c. in Asia, when people began expanding and leaving traces of their migration. d. in North America, because most archaeologists are from this continent.
Answer: a Feedback: The archaeological discipline was developed in Europe, and Eurocentric attitudes and interests meant that other areas around the world have not received as much attention as they should.See page 96.
In Paleolithic times, most people likely a. lived exclusively in caves (as evidenced by the art left behind and the protection from animals they received). b. did not live in caves (they were cold, dangerous, and away from resources like water). c. temporarily lived in caves for one to two seasons (as evidenced by the art left behind and the lack of tools discovered in cave middens). d. avoided caves entirely (cave art comes from a different time period).
Answer: b Feedback: Caves were not generally used for dwellings, and artifacts/art found there are better preserved (leading to high archaeological visibility and bias).See page 107.
The presence of bones at a site a. definitely means that those animals were eaten by the humans at that site. b. could be evidence of meat gathering strategies by humans, or could be naturally occurring remains of scavengers and other fauna of the time. c. means that those animals were naturally occurring around that site and did not interact with the people there. d. automatically classifies a site as a base camp.
Answer: b Feedback: It all depends on the context of the bones, which means definitive conclusions are not possible. One of the big problems archaeologists grapple with is how to tell the difference between bones from food animals and bones from animals that simply lived around the area.See page 97.
If you found a site that had clear evidence of butchering and remains from people living there an extended amount of time, it would likely be categorized as a a. base camp. b. resource processing site. c. habitation site. d. fire hearth.
Answer: c Feedback: A site where people lived for any amount of time is a habitation site.See page 93.

The time period, region, and one example of people from the Upper Paleolithic period is: a. 300,000 to 40,000 years ago; Africa, West Asia, Europe; Neandertals b. 2.5 million to 300,000 years ago; Africa, Asia, Europe; Homo erectu sc. 40,000 to 15,000 years ago; mostly Europe; Homo sapiens d. prior to 2.5 million years ago; Africa; Australopithecus afarensis
Answer: c Feedback: The Upper Paleolithic is rarely used outside of Europe, and primarily refers to the culture and peoples who replaced Neandertals in Europe beginning about 40,000 years ago.See page 96.
Unlike other animals, humans could expand into new territories because a. bipedalism is the only locomotive method that allows long distance migrations. b. they were able to take advantage of a very specific and narrow window of time/weather that occurred. c. they were able to use the night stars as a map/guide. d. they were not dependent on biology for survival.

8. Which of the following would have been a likely hunting scenario for early humans? a. An individual using an atlatl to fell a mammoth. b. Women designing traps for caribou. c. Hunting deer with a bow and arrow. d. A group of people chasing a bison for days until it was too exhausted to run anymore..
Answer: d Feedback: Mammoths are too large a prey to be felled by a single person and an atlatl, bows and arrows were not invented yet, and men likely did most of the hunting (and there is no evidence of such traps). Chasing animals until they were exhausted is a known strategy.See page 100
10. Assume there are no fish bones found at a site you are excavating. You can conclude a. fish were never eaten or used by the people at this site. b. the excavation was improperly completed, since the site is near a river and you expected to find fish. c. any possible fish remains must have been eaten by scavengers. d. that there are a number of possibilities; for example, fish may have still been eaten since the bones could be very old, relatively fragile, or simply not found yet.
Answer: d Feedback: The absence of something from the archaeological record does not mean it never existed. It is hard to draw concrete conclusions from low-visibility artifacts.
32. It is difficult to determine exactly when people started controlling fire because a. even evidence such as charred bones could be explained through natural fires and scavenging. b. the nature of fire means that all evidence of it is burned away, leaving nothing in the archaeological record. c. there are two main competing theories (one suggesting fire use 5 million years ago, another suggesting 1 million years ago) that each have their own sets of evidence. d. early humans purposefully hid all evidence of fire use.
a. even evidence such as charred bones could be explained through natural fires and scavenging. page 101 paragraph 3
35. A difference between Oldowan and Acheulean tools is a. how they were made: Oldowan are unifacial (flakes taken from one side), whereas Acheulean are bifacial (flakes taken from both sides). b. their respective time periods: Acheulean tools were the precursors to Oldowan tools, being used millions of years earlier. c. how they were used: Oldowan were used for large mammals (like mammoths) while Acheulean were used for small mammals (like deer). d. who made them: men are known to have made Acheulean tools for their hunting purposes, while women made Oldowan tools for tasks associated with gathering.

16. The majority of archaeological sites have been found in Europe. This is because a. the archaeological discipline was developed in Europe, and Eurocentric attitudes and interests meant that other areas around the world have not received as much attention as they should. b. the majority of sites where prehistoric peoples lived exist in Europe, so it makes sense that they would be more often found and excavated there. c. only European-trained archaeologists have sufficient skillsets to excavate archaeological sites, and many of them complete excavations close to home. d. Europe has less strict policies regarding prehistoric assemblages and remains; it is therefore the preferred destination for archaeologists worldwide.

the average amount of cutting edge produced from a single pound of stone
archaeological record
the basic facts about the past, based on the physical remains of human activity
Significance of meat and the adoption of hunting strategies clearly increased with
the emergence of homo erectus
Stratification likely started in
upper palaeolithic
The drive force of increased hunting strategies could be
using fire for cooking but is controversial
