primate fossils were found in what is now:
Correct Answer
D. All of these
Explanation
The correct answer is "all of these" because the first undisputed primate fossils have been found in Europe, Africa, Asia, and North America. This suggests that primates originated and evolved in different parts of the world, rather than being confined to a single continent. The discovery of primate fossils in multiple locations supports the idea that primates have a long and diverse evolutionary history.
6.
Which is the best explanation for the origin of the New World primates?
Correct Answer
D. They descended from primates that "rafted" from Africa to South America.
Explanation
The best explanation for the origin of the New World primates is that they descended from primates that "rafted" from Africa to South America. This suggests that these primates crossed the ocean on floating vegetation or other natural rafts, eventually reaching South America and evolving into the New World primates. This explanation is supported by genetic and fossil evidence, which show similarities between New World and Old World primates, indicating a common ancestry. It also explains why New World primates are found exclusively in South and Central America, as they would have been isolated from the primates in Africa and Asia.
7.
Monkeys appeared in the fossil record:

This could be due to various factors such as differences in geological conditions, limited fossil preservation, or lack of suitable habitats for early apes in North America.
10.
The fossil known as Lucy is particularly remarkable because:
Correct Answer
C. She is almost 40% complete even though over 3 million years old.
Explanation
The correct answer is that Lucy is almost 40% complete even though over 3 million years old. This is remarkable because fossilization is a rare occurrence and it is even rarer for a fossil to be so well-preserved and complete after millions of years. Lucy's level of completeness provides scientists with valuable information about her anatomy and allows for a more accurate understanding of our early human ancestors.
11.
Lucy is considered to be a hominin because:
Correct Answer
D. She was habitually bipedal.
Explanation
Lucy is considered to be a hominin because she was habitually bipedal. This means that she walked on two legs, which is a characteristic that distinguishes hominins from apes. The other options, such as her brain size, teeth, and body proportions, may also be relevant in classifying Lucy as a hominin, but the key characteristic that sets her apart is her habitual bipedalism.
12.
Which of the following has NOT been proposed as an advantage of bipedalism?
Correct Answer
D. Is more energy efficient for running.
Explanation
Bipedalism has been proposed as an advantage for various reasons, including the ability to walk and carry things simultaneously, giving a better view by elevating the head, and helping to keep the body and head cooler. However, it has not been suggested that bipedalism is more energy efficient for running.
13.
The latest evidence suggests that bipedal locomotion may have first evolved:
Correct Answer
C. In a mixed savanna / forest environment.
Explanation
The latest evidence suggests that bipedal locomotion may have first evolved in a mixed savanna / forest environment. This is supported by the fact that early hominins, such as Ardipithecus ramidus, were found in environments that consisted of both savannas and forests. These mixed environments would have provided a variety of resources, such as food and shelter, which would have favored the development of bipedalism as a means of efficient movement and foraging. Additionally, the presence of both open spaces and trees would have allowed for a combination of walking and climbing, which is characteristic of bipedalism.
14.
At present, the earliest
proposed hominin fossil is:

Australopithecus species are believed to have lived between 4.2 and 1.9 million years ago and are considered to be a key part of human evolution. These early hominins had a combination of ape-like and human-like features and are believed to have walked upright. They are an important link in understanding the transition from ape-like ancestors to early humans in the evolutionary timeline.
16.
The major difference between members of genera
Australopithecus and Paranthropus is in:
Correct Answer
D. Robusticity of chewing area and chewing muscles
Explanation
The major difference between members of the genera Australopithecus and Paranthropus is in the robusticity of the chewing area and chewing muscles. This means that Paranthropus species had a more robust and powerful chewing apparatus compared to Australopithecus species. This difference in robusticity suggests that Paranthropus species had a specialized diet that required more forceful chewing, possibly consisting of tougher and harder foods. In contrast, Australopithecus species had a less robust chewing apparatus, indicating a different dietary adaptation.
17.
The evolution of genera
Paranthropus and Homo took place approximately:
Correct Answer
C. 3 million years ago
Explanation
The correct answer is 3 million years ago. This is based on the understanding of the fossil record and the dating of various hominin species. Paranthropus and Homo are two different genera of hominins, with Paranthropus existing from about 2.7 to 1.2 million years ago, and Homo appearing around 2.8 million years ago. Therefore, the evolution of these two genera likely occurred around 3 million years ago.
18.
The evolution of genera Paranthropus and Homo may have been a response to:
Correct Answer
A. An expansion of the dry savannas.
Explanation
The evolution of genera Paranthropus and Homo may have been a response to an expansion of the dry savannas. This could be because the dry savannas provided a new habitat for these species to adapt to and exploit. The expansion of the dry savannas would have created new ecological niches and resources that these genera could have taken advantage of, leading to their evolution. The dry savannas may have offered different food sources, shelter, or other environmental factors that favored the survival and adaptation of Paranthropus and Homo species.
19.
The earliest members of
genus Homo were placed in that genus because of their:
Correct Answer
B. Increased brain size
Explanation
The earliest members of the genus Homo were classified as such due to their increased brain size. This characteristic distinguished them from earlier hominin species and indicated a significant evolutionary development. The larger brain size likely contributed to advancements in cognition, problem-solving abilities, and social behavior, setting the stage for the further development of the Homo genus and the emergence of modern humans.
20.
Culturally, the earliest
members of genus Homo are associated with:
Correct Answer
D. The first stone tools
Explanation
The earliest members of the genus Homo are associated with the first stone tools. Stone tools, such as handaxes and scrapers, were the earliest evidence of technology and tool-making skills by early humans. These tools were essential for various activities like cutting, scraping, and hunting. The development and use of stone tools marked an important milestone in human evolution, showing increased cognitive abilities and problem-solving skills. The use of fire, modern-like human language, and big game hunting came later in human history and were not directly associated with the earliest members of the genus Homo.
21.
A major use of stone tools for early Homo which has left concrete evidence is:
Correct Answer
B. To aid in dismembering scavenged carcasses for meat.
Explanation
Stone tools were essential for early Homo in aiding in dismembering scavenged carcasses for meat. This is supported by concrete evidence, as archaeologists have discovered stone tools with distinctive marks and wear patterns that indicate their use in butchering and processing animal remains. These tools would have been crucial for early humans to access and utilize valuable sources of protein, contributing to their survival and development.
22.
Physically, the Homo
erectus stage is NOT characterized by:
Correct Answer
A. Modern brain size
Explanation
The Homo erectus stage is not characterized by modern brain size. This means that during this stage, the brain size of Homo erectus was not comparable to the brain size of modern humans. While Homo erectus did have an increase in brain size over earlier hominids, it did not reach the level of modern humans. However, Homo erectus did exhibit modern body size and modern body proportions, indicating that there were physical changes occurring during this stage.
23.
Fossils of Homo erectus are
first found:
Correct Answer
C. 1.8 million years ago in Africa
Explanation
Homo erectus fossils were first found 1.8 million years ago in Africa. This suggests that Homo erectus originated in Africa and then spread to other regions. The fossils found in Java and Europe are believed to be descendants of the African population, indicating their migration and adaptation to different environments. This finding supports the theory of human evolution and the African origin of Homo erectus.
24.
Homo erectus is the first hominid to:
Correct Answer
A. Expand out of Africa
Explanation
Homo erectus is considered the first hominid to expand out of Africa. This species of early humans migrated from Africa to different parts of the world, including Asia and Europe. This expansion is significant because it marked a major milestone in human evolution, as it led to the colonization of new territories and the adaptation to diverse environments. While Homo erectus did make stone tools and walked upright, these characteristics were not unique to this species and were also present in earlier hominids. Additionally, achieving modern brain size occurred in later hominid species.
25.
Which of the following
cultural achievements is NOT associated with Homo erectus?
Correct Answer
D. Building of shelters
Explanation
Building of shelters is not associated with Homo erectus because they were primarily nomadic, meaning they did not settle in one place long enough to build permanent structures. Homo erectus is known for their use of fire, the development of the hand axe, and the use of flake tools, but there is no evidence to suggest that they built shelters.
26.
Fossils of Homo erectus are
found:
Correct Answer
A. All over the Old World
Explanation
Homo erectus fossils have been found all over the Old World, which includes regions such as Africa, Asia, and Europe.

The other options either precede or extend beyond the accepted time range for the Pleistocene period.
30.
The author of the text suggests that the most important use of fire by Homo erectus was:
Correct Answer
D. As a source of light, a social focus, and a sense of mastery over nature.
Explanation
The author suggests that the most important use of fire by Homo erectus was as a source of light, a social focus, and a sense of mastery over nature. This implies that fire served not only practical purposes such as providing heat and cooking meat, but also had significant social and psychological implications for early humans. Fire would have allowed them to gather around a central source of light, fostering social interaction and creating a sense of community. Additionally, the ability to control and utilize fire would have given Homo erectus a feeling of power and control over their environment, enhancing their sense of mastery over nature.
31.
Archaic Homo sapiens are given the prefix "archaic" because:
Correct Answer
D. They retained some primitive pHysical features of the skull.
Explanation
Archaic Homo sapiens are given the prefix "archaic" because they retained some primitive physical features of the skull. This suggests that they had characteristics that were more similar to earlier hominin species, rather than modern humans. These physical features could include a more pronounced brow ridge, a larger face, and a larger jaw. By using the term "archaic," it highlights the fact that these individuals had not yet evolved to possess the more modern physical traits seen in anatomically modern humans.
32.
Archaic Homo sapiens, despite the prefix "archaic," are placed in our species because:

Explanation
Archaic Homo sapiens fossils first appear about 700,000 years ago. This means that evidence of early humans with characteristics similar to modern humans can be traced back to this time period. These fossils provide insights into the evolution and development of our species.
34.
The famous group of fossil
humans known as the Neandertals is considered by the text to be included in:
Correct Answer
B. Archaic Homo sapiens
Explanation
The Neandertals, according to the text, are classified as archaic Homo sapiens. This means that they are considered to be an early form of Homo sapiens, but not anatomically modern. The term "archaic" implies that they are a more primitive or ancestral form of Homo sapiens, while still belonging to the same species. This classification suggests that the Neandertals are closely related to modern humans, but exhibit some distinct anatomical and genetic differences.
35.
Fossils of Neandertals were
first discovered:
Correct Answer
D. During Darwin's lifetime
Explanation
During Darwin's lifetime, fossils of Neandertals were discovered. This suggests that the discovery of Neandertal fossils predates the other options given in the question. Darwin lived from 1809 to 1882, so it is possible that Neandertal fossils were discovered during this time.
36.
The Neandertals lived:
Correct Answer
B. In Europe and Southwest Asia
Explanation
The Neandertals lived in Europe and Southwest Asia. This is supported by archaeological evidence that shows their presence in these regions during the Middle Paleolithic period. Neandertal remains have been found in various sites across Europe, including Germany, France, and Spain. Additionally, fossil evidence and genetic studies indicate that Neandertals interbred with early modern humans in these regions. Therefore, the correct answer is that they lived in Europe and Southwest Asia.
37.
The Neandertals differed
from modern humans in all the following EXCEPT:
Correct Answer
C. Brain size
Explanation
The Neandertals differed from modern humans in terms of forehead slope, chin shape, and body robustness. However, they did not differ in brain size. Neandertals had a similar or even slightly larger brain size compared to modern humans.
38.
The short stature and
stockiness of the Neandertals has been interpreted as:
Correct Answer
C. An adaptation to cold climate
Explanation
The short stature and stockiness of the Neandertals is believed to be an adaptation to cold climate. This is because having a more compact body helps in conserving heat and reducing surface area exposed to the cold. A larger body also helps in retaining heat, as it has a smaller surface area-to-volume ratio. Additionally, the shorter limbs of Neandertals would have helped reduce heat loss in extremities. These physical characteristics suggest that Neandertals were well-suited to survive in the cold environments they inhabited.
39.
Which of the following is associated with Neandertal material culture?
Correct Answer
D. The possible first use of hafting.
Explanation
The possible first use of hafting is associated with Neandertal material culture. Hafting is the process of attaching a handle or haft to a tool or weapon, which allows for better control and efficiency in its use. This advancement in tool technology was significant and is often attributed to Neandertals, indicating their ability to innovate and adapt to their environment.
40.
Which of the following is NOT associated with the material culture of the Neandertals?
Correct Answer
B. Stone blades with artistic rather than utilitarian use.
Explanation
The Neandertals were known for their advanced material culture, including the use of hafting, retouching of flakes produced by the Levallois technique, woodworking, and antler carving. However, there is no evidence to suggest that they used stone blades for artistic purposes rather than utilitarian use.
41.
. Which of the following is NOT accepted evidence of abstract belief among the Neandertals?
Correct Answer
B. Remnants of formalized religious ritual.
Explanation
The correct answer is "remnants of formalized religious ritual." This means that there is no accepted evidence of Neanderthals engaging in formalized religious rituals. While burial of the dead, care of the elderly and injured, and inclusion of offerings in graves are all considered evidence of abstract belief among Neanderthals, there is no indication of formalized religious rituals being practiced by them.
42.
