Exam 4: Genes, Evolution, and Behaviour

Psychologist David Buss studies the dating and mating behaviours of human beings.The facial features we associate with female beauty-big eyes,clear skin,full lips-are strongly correlated with health and fertility.Therefore,Buss says,early men who chose beautiful women who met these criteria were more likely to have healthy children and pass on this appreciation of beauty.Based on this information,we can say that Buss is a/an ____________________ psychologist.

Research suggests that the environment accounts for only about 50 percent of the variation of the divorce rate.If the remaining 50 percent is affected by genes,we can say that.50 is the ___________ for the likelihood of divorce.

Psychological disorders appear only if they're triggered by stressors in the environment,so inheriting the genetics for a particular disorder doesn't doom someone to have that disorder.Panic disorder runs in Allie's family,but because the environment never triggered it,she has no problems with it.We can say that panic disorder is part of Allie's

Tahki and Waneta are identical twins,but they were separated at birth and raised in different countries.When they meet as adults,they talk about all the ways in which they are the same,but also the ways in which they are different.Compared to identical twins who have been raised together,Tahki and Waneta probably

Siblings Alisa and Erika were born at the same time but are very different both in terms of looks and personality.We can therefore assume they are ___________ twins.

Carol's parents live in southern Florida,where anoles (small lizards)are common.Every time she visits,Carol removes more anoles from inside her parents' pool cage.There is no way for new anoles to get into the cage,so all the anoles there now are either the original interlopers or their offspring that have inherited the qualities that allowed the original anoles to escape capture.As a result,the anoles that are still inside the cage,including the babies,are very difficult to catch and remove.On a microcosmic level,the increasingly clever anoles in the pool cage are the result of

When teaching about evolutionary psychology,Dr.Karikomi notices that his students often make inaccurate assumptions about how adaptation and natural selection work.Which of the following is false about evolution?

You have applied for your dream job in Vancouver.The company has decided to hire you,but first you must come in to complete some paperwork,and to meet with the company doctor to complete a physical exam.You are young and healthy and eager to begin your new job.However,once the tests are complete,they call to say they cannot hire you because your blood work indicates you are predisposed to develop a disabling disorder.You speak to a lawyer who tells you that:

Identical twins have 100 percent of their genes in common,though people who know them often emphasize their personality differences.Therefore,we can say that twins have the same _______________,but environmental influences may affect each twin's _________________.

Evolutionary theory suggests that males are genetically more likely to be promiscuous than females.Some people use this as a flawed argument that men can't be expected to stay faithful.Those people are relying on the idea of

Evolutionary theory suggests that several personality traits are found in all humans,because they had adaptive functions.These traits are collectively referred to as the

Early women who had sex before securing a commitment were more likely to be left without a partner to help during the pregnancy and childrearing.Proponents of _____________ theory would argue that many modern women's tendency to insist on some indication of commitment before having sex is a direct,inherited,and adaptive result.

Paolo tried to remove a broken light bulb from a socket with his bare hands,without turning off the circuit breaker.He had a shock and has been very careful with broken bulbs ever since.The tendency not to do something painful twice therefore has

Studies show that creative people have more problems with mood disorders than do people who are not creative.To determine whether this correlation has any genetic basis,researchers would need to

A mother alligator lays a clutch,or group,of eggs.When the babies hatch,one has a white hide,rather than the normal green.The white alligator grows normally and is as healthy as its siblings,but it's definitely easier to see against the green lake area in which the alligators live.What caused the white alligator's hide to be different from those of its siblings and parents?
