Question 1

Aside from the extreme ends of the height spectrum, the human species exhibits about a ____ percent variation in height overall.

Accepted Answer

The human species exhibits about a 10 percent variation in height overall, aside from the extreme ends of the height spectrum. This variation is influenced by a combination of genetic factors, environmental conditions, and nutritional status during growth periods.

Question 2

Which of the following statements is NOT true?

Accepted Answer

Humans do not vary more than most similarly-sized mammals in genetic patterns. In fact, humans have less genetic variation compared to many other species, including some mammals. This is likely due to a bottleneck effect that occurred in our evolutionary past, reducing our genetic diversity.

Question 3

Taking into account variation in stature and body shape across the globe, the variation in the size of a fully functional, normal human brain ranges between

Accepted Answer

The variation in the size of a fully functional, normal human brain typically ranges between 1000 and 2000 cubic centimeters (cc). This range accounts for differences in body size, gender, and other factors across the global population.

Question 4

According to the text, human body size and shape are determined in large part by all of the following EXCEPT

Accepted Answer

Culture influences many aspects of human life, but human body size and shape are primarily determined by biological factors such as natural selection, gene flow, and nutrition, rather than cultural factors.

Question 5

Simple measures of cranial shape yield a(n)

Accepted Answer

The cephalic index is a simple measure of cranial shape, calculated as the ratio of the maximum width of the head to its maximum length.
