Question 1

Which of the following statements about techniques used in dating fossil remains is NOT true?

Accepted Answer

Carbon-14 dating is most accurate for specimens that are younger than about 50,000 to 60,000 years. Beyond this range, there is too little Carbon-14 left in the specimen to accurately determine its age, making statement D incorrect.

Question 2

The principle of superposition states that in an undisturbed sequence of strata,

Accepted Answer

The principle of superposition, a key concept in geology and stratigraphy, asserts that in an undisturbed sequence of sedimentary rocks or strata, the oldest layer is at the bottom and each successive layer above it is younger than the one below.

Question 3

Which of the following is NOT one of the fields of study mentioned in the chapter as part of the multidisciplinary approaches used in biological anthropology and archaeology?

Accepted Answer

Metaphysics is not mentioned as part of the multidisciplinary approaches in biological anthropology and archaeology. It is a branch of philosophy that deals with the first principles of things, including abstract concepts such as being, knowing, substance, cause, identity, time, and space, rather than the practical, scientific methods and empirical findings that characterize the fields directly involved in these disciplines.

Question 4

Molecular anthropology

Accepted Answer

Molecular anthropology uses genetic analysis, such as DNA sequencing, to study evolutionary relationships and trace lineage, making option A the correct choice.

Question 5

What are both carbon-14 and potassium-argon dating techniques based on?

Accepted Answer

Both carbon-14 and potassium-argon dating techniques are based on the principle of radioactive decay, where unstable isotopes break down into stable forms at a predictable rate.

Question 6

Systematic survey and excavation

Accepted Answer

Systematic survey and excavation are fundamental to fieldwork in archaeology and paleoanthropology, as they help researchers locate and study material remains of past human life and cultures.

Question 7

What term refers to the study of the processes that affect the remains of dead animals?

Accepted Answer

Taphonomy is the branch of paleontology that deals with the processes of fossilization, including how organisms decay, become fossilized, and are discovered as fossils. It specifically studies the processes that affect animal and plant remains after death, including their burial, decomposition, and preservation in the fossil record.

Question 8

Which of the following is NOT one of the kinds of archaeology discussed in this chapter?

Accepted Answer

Linguistic archaeology is not recognized as a kind of archaeology; instead, linguistic anthropology is the correct term for the study of language and its impact on society.

Question 9

The utility of stratigraphy for dating purposes is based on the fact that

Accepted Answer

Stratigraphy is used for dating based on the principle that in undisturbed soil layers, the depth and order of soil strata reflect the sequence of their deposition, with older layers being deeper than newer ones.

Question 10

In an example of how microscopic evidence in studying the past can yield surprising results that may overturn long-held assumptions, Williamson's analysis of microscopic residues stuck to the edges of cutting tools found at a cave site in South Africa revealed that

Accepted Answer

Williamson's analysis revealed that 50 percent of the residues on the cutting tools were from plants, which contradicted the previous assumption that these tools were primarily used for hunting and butchering animals, thus providing new insights into the dietary habits of the tool users.

Question 11

Under what conditions are fossils most likely to form?

Accepted Answer

Fossils are most likely to form in areas covered by volcanic ash because the ash can quickly bury organisms, protecting them from decay and scavengers, and eventually hardening into rock that preserves the remains.

Question 12

The so-called Piltdown man was once considered an unusual and perplexing human ancestor, but it turned out to be the jaw of a young orangutan attached to a Homo sapiens skull. What dating technique exposed the Piltdown fraud?

Accepted Answer

Fluorine absorption analysis was the technique used to expose the Piltdown fraud. This method compares the amount of fluorine absorbed by bones from surrounding soil and groundwater. The discrepancy in fluorine content between the skull and the jawbone indicated they were not from the same time period, revealing the hoax.

Question 13

The specialist among a team of scientists at an excavation site who focuses on the study of ancient plants through pollen samples taken from the site is most likely a

Accepted Answer

A palynologist specializes in the study of pollen and spores, which includes analyzing ancient pollen samples to understand past vegetation and climates.

Question 14

Which of the following statements about paleoanthropologists is FALSE?

Accepted Answer

Paleoanthropologists, like all researchers, must adhere to ethical and legal standards, especially when handling human remains. This includes respecting the cultural and historical significance of the remains and complying with local and international laws.

Question 15

Which excavation technique provides more information about the context of the artifacts, fossils, or features discovered?

Accepted Answer

Digging through the strata one layer at a time allows archaeologists to understand the chronological sequence of the site, providing more context about the artifacts, fossils, or features discovered in relation to their depth and stratigraphic position.

Question 16

Radiometric dating techniques available to anthropologists

Accepted Answer

Radiometric dating techniques calculate the age of a specimen or surrounding rocks by measuring the decay of radioactive isotopes, providing a probable date for fossils. This method is not limited to nonhuman primates or inorganic materials, nor is it ineffective for hominin fossils due to their age. The development of these techniques predates 1991 and has significantly impacted the study of the fossil record across various species, including humans.

Question 17

Data collected using systematic surveys do NOT typically address which of the following questions?

Accepted Answer

Systematic surveys are primarily designed to locate sites, understand their spatial distribution, and sometimes assess their size, age, and the types of structures present. They do not typically involve excavation, which is necessary to establish the relative chronology of layers within a site.

Question 18

Advances in technology enable archaeologists to gather evidence that is not visible to the naked eye. One example of such microscopic evidence is the study of

Accepted Answer

Phytoliths are microscopic crystals found in many plants that are inorganic and do not decay, allowing archaeologists to determine which plants were present at a site even when other plant remains are not preserved.

Question 19

Paleopathology is the study of

Accepted Answer

Paleopathology focuses on understanding diseases and injuries in ancient human and animal skeletons, primarily through the examination of skeletal remains from archaeological contexts. This field helps us understand the health, lifestyle, and causes of death in past populations.

Question 20

Which of the following researchers is LEAST likely to be part of a paleoanthropological research team?

Accepted Answer

A psychotherapist, who focuses on the treatment of mental disorders by psychological rather than medical means, is least likely to be part of a paleoanthropological research team. Paleoanthropology combines aspects of archaeology and anthropology to study ancient humans, and thus, the expertise of a psychotherapist is not directly relevant to the field's primary research activities.
