1.
Biologically, race is a synonym for:
Correct Answer
A. Subspecies
Explanation
Race is a biological term used to categorize different populations within a species based on distinct physical characteristics. Subspecies refers to populations within a species that have developed unique traits due to geographical or environmental factors. Therefore, subspecies is the correct answer as it accurately represents the biological concept of race.
2.
The distribution of most phenotypic variation in most species may be described as:
Correct Answer
C. A continuum of gradual change
Explanation
The correct answer is "a continuum of gradual change." This means that the phenotypic variation in most species is not restricted to discrete clusters or specific environmental conditions, but rather exists on a spectrum of gradual change. This suggests that there is a range of phenotypes within a species, with intermediate forms between distinct traits. This gradual change can be influenced by various factors such as genetic variation, natural selection, and environmental factors.
3.
A continuum of gradual change in phenotypic features across geographical space is called a:
Correct Answer
B. Cline
Explanation
A continuum of gradual change in phenotypic features across geographical space is called a cline. This term is used to describe the variation in traits or characteristics of a species that gradually change from one population to another along a geographical gradient. It suggests that there is no clear-cut boundary or distinct categories, but rather a gradual transition. This concept is important in understanding the complexity and diversity of species distribution and adaptation to different environments.
4.
Populations within a species that still can interbreed but don't because of isolation are referred to as:
Correct Answer
D. Semispecies
Explanation
Populations within a species that can still interbreed but do not due to isolation are referred to as semispecies. This term is used to describe populations that are in the process of speciation, where they are on their way to becoming distinct species but are not yet fully reproductively isolated. This can occur due to geographical barriers or other factors that prevent gene flow between populations, leading to the development of unique traits and characteristics.
5.
Correct Answer
A. Population that is isolated from others but still capable of interbreeding
6.

C. Susceptibility and resistance to disease
15.
What feature of our species is most important for accounting for the fact that we cannot be divided into biologically meaningful racial or subspecies groups?
Correct Answer
C. Mobility and gene flow
Explanation
The most important feature of our species that explains why we cannot be divided into biologically meaningful racial or subspecies groups is mobility and gene flow. This means that humans have historically migrated and interbred with different populations, leading to the mixing of genetic traits across different regions. This constant movement and exchange of genes has prevented the development of distinct and isolated groups that could be categorized as separate races or subspecies. Instead, human populations exhibit a wide variety of genetic diversity that is not easily classified into discrete categories.
16.
Which of the following is NOT a reason why we say that human races don't exist on a biological level?
Correct Answer
C. Recognizing race leads to social inequalities
Explanation
Recognizing race leads to social inequalities because it promotes the idea that certain races are superior or inferior to others, leading to discrimination and unequal treatment based on race. This statement suggests that the non-existence of human races on a biological level is not related to the recognition of race leading to social inequalities.
17.
The human species is so genetically homogeneous that we all share _______ percent of our species' genes.
Correct Answer
D. 99% +
Explanation
The human species is so genetically homogeneous that we all share over 99% of our species' genes. This means that despite our physical differences, we are all incredibly similar at the genetic level. This high level of genetic similarity is what allows us to be classified as the same species.
18.
To say that human race is a folk taxonomy means that:
Correct Answer
D. It is an example of a set of cultural categories
Explanation
The statement suggests that the term "human race" is a folk taxonomy, meaning it is a cultural category rather than a scientific or objective classification. This implies that the concept of race varies across different cultures and does not have a universal or inherent meaning. It highlights the idea that race is a social construct shaped by cultural beliefs and practices.
19.
Correct Answer
A. European racial categories and attitudes
20.
Correct Answer
C. Judging an individual solely on the basis of his or her racial affiliation
21.
The native peoples of Tasmania, when contacted by Europeans in the 17th century, had a relatively uncomplex culture largely because:
Correct Answer
A. They were almost totally isolated from other human societies
Explanation
The correct answer is that the native peoples of Tasmania had a relatively uncomplex culture largely because they were almost totally isolated from other human societies. This isolation limited their exposure to external influences and prevented the development of more complex cultural practices and technologies that often result from interactions with other societies.
22.
Diffusion of inventions and ideas was more efficient in Eurasia because:
Correct Answer
D. They could move greater distances without changing latitudes
Explanation
The ability to move greater distances without changing latitudes in Eurasia allowed for easier diffusion of inventions and ideas. This is because similar latitudes often share similar climates and environmental conditions, making it easier for people to adapt and transfer knowledge across regions. In contrast, regions with significant changes in latitude often have different climates and environments, making it more challenging for inventions and ideas to spread efficiently. Therefore, the ease of movement without changing latitudes in Eurasia facilitated the exchange of innovations and knowledge, contributing to more efficient diffusion in the region.
23.
The process of diffusion accounts for what percent of a society’s cultural inventory on average?
Correct Answer
A. 90%
Explanation
Diffusion refers to the spread of cultural traits, ideas, and practices from one society to another. The given answer, 90%, suggests that the process of diffusion accounts for a significant portion of a society's cultural inventory on average. This means that a large percentage of a society's cultural elements, such as language, technology, customs, and beliefs, are acquired through diffusion from other societies. It indicates the importance of cultural exchange and interaction in shaping and enriching a society's cultural diversity.
24.
Relative degree of cultural complexity is mostly linked to:
Correct Answer
B. Access to other cultures and their ideas and inventions
Explanation
The relative degree of cultural complexity is mostly linked to access to other cultures and their ideas and inventions. When a culture has exposure to different cultures, it has the opportunity to learn from their ideas and inventions, leading to the development of new technologies, systems, and ways of life. This exchange of knowledge and innovation promotes cultural complexity as it allows for the integration and adaptation of diverse cultural elements. The inventiveness of the people within a culture and the degree of intelligence among a society's people can contribute to cultural complexity, but they are not the primary factors. Distance from the equator and colder conditions promoting more complexity is not a valid explanation.
25.
The connection between race and IQ is:
Correct Answer
D. Cultural
Explanation
The correct answer is cultural because the connection between race and IQ is not determined by biological or genetic factors. Numerous studies have shown that IQ differences among different racial groups can be attributed to cultural and socio-economic factors, such as access to education, opportunities, and societal biases. These factors have a significant impact on cognitive development and performance on IQ tests, rather than any inherent biological or genetic differences between races.
26.
IQ tests are said to have "reified" intelligence. This means that IQ tests:
Correct Answer
D. Reduced a complex idea into a single entity, in this case a number
Explanation
IQ tests are said to have "reified" intelligence, meaning that they have reduced the complex idea of intelligence into a single entity, which is represented by a number. This suggests that IQ tests simplify the concept of intelligence, making it easier to quantify and measure. Instead of considering intelligence as a multifaceted and nuanced trait, IQ tests condense it into a single numerical value, which may not fully capture the complexity of human intelligence.
