Question 1

Ginger just joined the dating scene after being single for six months.She is 20 years old,attractive,heterosexual,and a student.According to evolutionary theory,which of the following men would Ginger prefer to date,assuming she is looking for a potential mate?

Accepted Answer

According to evolutionary theory, women are attracted to men who display characteristics of good providers and protectors. Sam, the 27-year-old dentist who coaches little league in the summer, is more likely to have financial stability and show qualities of a caring and nurturing partner. Therefore, Ginger would likely prefer to date Sam over the other options.

Question 2

Across different human cultures,there are some specific mate preferences,such as a preference for symmetrical faces.According to your text,these preferences may have evolved for all of the following reasons EXCEPT

Accepted Answer

The text does not mention mate preferences evolving to suggest the stability of an individual's intellectual abilities. The other options, A, C, and D, are mentioned as reasons for the evolution of specific mate preferences.

Question 3

When it comes to traits that humans find attractive in a potential mate,which of the following is NOT true?

Accepted Answer

Facial preferences can vary, but generally, females tend to prefer males with more masculine features, while males may prefer females with more feminine features. The statement that both sexes prefer more feminine facial features in their partner is not universally true, especially considering the general preference among females for males with more masculine facial features.

Question 6

Your twenty-two-year-old friend has just told you that she is dating a fifty-five-year-old man.According to David Buss,which of the following might explain the attraction between this couple?

Accepted Answer

According to David Buss's theory of mate selection, men are attracted to younger, more fertile partners who can bear offspring, while women are attracted to older, more established partners who can provide resources and support. Therefore, it is likely that the older male in this situation is attracted to the younger female's fertility, while she is attracted to his resources and stability. Choice B best reflects these factors.

Question 7

According to David Buss,what is a key gender difference in mate selection?

Accepted Answer

According to David Buss and his research on evolutionary psychology, one of the key gender differences in mate selection is that males tend to prefer younger females who are perceived to be more fertile and capable of reproducing, while females tend to prefer males who possess greater resources, such as wealth, status, and power.

Question 8

Which of the following behaviours is most likely to influence the reproductive success of an organism?

Accepted Answer

Mate selection and parenting of offspring are both behaviors that influence an organism's reproductive success. Mate selection plays a critical role in determining the quality of the genetic material passed on to offspring, while parenting behavior determines the survival and success of the offspring. Physical traits can also influence reproductive success, but they are not necessarily behavioral in nature.

Question 9

Alya is visiting a zoo and notices that one male peacock has a really scrawny,thin tail compared to the other peacocks.Furthermore,this one sad looking peacock is completely ignored by all the peahens.What is most likely the reason for this?

Accepted Answer

Peahens are known to prefer peacocks with longer tails that have more "eyes" as they are associated with health and reproductive fitness. This preference is likely due to sexual selection, where females choose mates based on certain traits that indicate high genetic quality. The scrawny peacock with a thin tail is likely not chosen by the peahens because he does not display these desirable traits.

Question 14

Unfortunately,there is no tissue evidence from early Hominids for modern man to study and learn about their brains.As such,how do we know that brain size has increased considerably in Hominids?

Accepted Answer

We know that brain size has increased in Hominids because we have evidence from fossilized skulls that show an increase in cranial capacity. By measuring the size and shape of the skull, scientists can estimate the size of the brain that it contained. This has allowed us to track the increase in brain size over time in the human evolutionary lineage.

Question 15

Which of the following offers the best evolutionary explanation of why we have specific preferences for certain characteristics in mate selection?

Accepted Answer

Evolutionary theory suggests that certain characteristics may signal good health and reproductive fitness in potential mates, increasing the likelihood of successful reproduction and passing on those desirable traits to offspring. This combination of genetic and adaptive advantages is thought to contribute to our evolved preferences for certain mate selection criteria.
