Description: How the human brain evolved over hundreds of thousands of years to become what it is today. And it’s a miracle how our brain thinks we still live in the era of sabertooth cats and mammoths and, therefore, acts, thinks, and behaves like the treat of those is real. Read this to understand our brains and why it operates the way it does in the world today.


My notes:


1. The Scientific Movements Leading to Evolutionary Psychology


This “argument from ignorance,” or as Dawkins (1982) calls it, “the argument from personal incredulity,” ( :14)

“there, he speculated that many cherished human phenomena, such as culture, religion, ethics, even aesthetics, would ultimately be explained by the new synthesis. These assertions only contradicted the dominant theories in the social sciences. Culture, learning, socialization-, rationality, and consciousness, not evolutionary biology, were presumed by most social scientists to explain the uniqueness of humans.” ( :22)

“decade after Watson’s major work, a young Harvard graduate student named B. F. Skinner needed a new brand of environmentalism called radical behaviorism and a principle of preconditioning. According to this principle, the reinforcing consequences of behavior were the local causes of subsequent behavior. Behavior followed by reinforcement would be repeated in the future. Behavior not followed by reinforcement (or followed by punishment) would not be repeated in the future. All behavior, except random behavior, could be explained by the “connected”of reinforcement.” ( :32)

“. Perhaps the most influential was Margaret Mead,who purported to have disc ered cultures in which the “sex roles” were totally reversed and sexual jealousy entirely abs Mead depicted island paradises inhabited by peaceful peoples who celebrated shared sexua and free love and did not compete,rape,fight,or murd” ( :33)

“Derek Freeman (1983), for example, found that the Samoan islanders whom Mead had depi in such utopian terms were intensely competitive and had murder and rape rates higher t those in the United State” ( :33)

“generate behavior as output. The idea that humans might come predisposed or specially equipped to process some ds of information and not others set the stage for the emergence of evolutionary psycho” ( :38)


2. The New Science of Evolutionary Psychology


“t, it cannot be tested because specific empirical predictions do not follow from its major mise. Wh” ( :42)

“t, it cannot be tested because specific empirical predictions do not follow from its major mise. Whatever exists does so simply because the Supreme Being has created it. Second, ationism has not guided researchers to any new scientific discoveries. Third, creationism not proved useful as a scientific explanation for already discovered organic mechanisms.” ( :42)

“rs, 1985). The male pipefish seahorse receives the eggs from the female and then carries th around in his kangaroo-like pouch. These females compete aggressively with each other for “best” males, and males in turn are choosy about who they mate with. This so-called “sexreversed” species supports Trivers’s theory, showing that it is not “maleness” or “femalen itself that caus” ( :47)

“Psychologist Devendra Singh has proposed one such feature: the ratio of the wais the hips, or WHR (Singh, 1993). A low WHR, indicating that the waist is smaller in circ ference than the hips, is linked with fertility for two reasons. First, women in fertility c ics with low WHRs get pregnant sooner than women with higher WHRs. Second, wo with higher WHRs show a higher incidence of heart disease and endocrinological proble both of which are linked with lower fertility. So Singh proposed that men will prefer wo with low WHRs and that a desire evolved in men to home in on this powerful physical to women’s fertilit” ( :51)

“henomenon occurs. Two conclusions about this “bottom-up”strategy of generating and testing hypotheses be drawn. First, it is perfectly legitimate for scientists to observe phenomena and subseque formulate hypotheses about their origins and functions. In astronomy, for example, the find of the expanding universe was observed first, followed by theories that attempted to explai The bottom-up strategy provides a nice complement to the “top-” ( :51)

“mans also have a nature—qualities that define us as a unique species—and all chological theories imply its existence. For Sigmund Freud, human nature consisted of ory of radical behaviorism, assume that humans have a nature—in this case, consisting of w highly general learning mechanisms.” ( :52)

“the eye is not an all-purpose seeing device. It is designed to process only row subsets of information—waves within a particular range of frequency, edges, motion, so on—from among the much larger domain of potential information.” ( :54)

“magine giving” ( :56)

“m, the greater the number of response options there will be. Consider a carpenter’s toolbox. The carpenter gains flexibility not by having one “highly eral tool” that can be used to cut, poke, saw, screw, twist, wrench, plane, balance, and ham- . Instead, th” ( :58)

“data sources have limitations. The fossil record is fragmentary and has large gaps. With temporary hunter-gatherers, we do not know the degree to which current practices are taminated by modern influences. In self-reports, people may lie or fail to know the truth. h observational reports, many important domains of behavior are hidden from prying s; those that are not may be distorted due to observer bias. Laboratory experiments are n contrived and artificial, rendering their generalizability to real-world contexts stionable. Life data from public records, although seemingly objective, can also be ject to systematic biases. E” ( :70)


3. Combating the Hostile Forces of Nature: Human Survival Problems


“ave for avoiding danger. Fear is a vital evolutionary legacy that leads an organism to avoid threat,and has obvious surv value. It is an emotion produced by the perception of present or impending danger and is nor in appropriate situations. Without fear few would survive long under natural conditions. girds our loins for rapid action in the face of danger and alerts us to perform well under stres helps us fight the enemy, drive carefully, parachute” ( :95)

“e inherited effects of real dangers . . . ing ancient savage time?” (Darwin, 1877, pp. 285-294). Humans are far more likely to deve fears of dangers that were present in the ancestral environment than of dangers in the current e ronment. Snakes, for example, are hardly a problem in large urban cities, but automobiles Fears of cars,guns,electrical outlets,and cigarettes are virtually unheard of,since these are ev tionarily novel hazards—too recent for selection to have fashioned specific fears. The fact more city dwellers go to psychiatrists with fears of snakes and strangers tha” ( :97)

“rabbits are more likely to die (Kluger,1990). Early in the twentieth century, a physician named Julius Wagner-Jauregg observed that hilis was rarely seen in places where malaria was common (Nesse & Williams, 1994). At time,syphilis killed 99 percent of those who were infected.

4. Men’s Long-Term Mating Strategies


“Another benefit of marriage is an increase in the quality of the woman a man woul able to attract. Men who are willing to promise long-term resources, protection, and investm in children are appealing to women, so men who are willing to commit to the long term ha wider range of women from which to choo” ( :111)

“r ancestors had access to two types of observable evidence of a woman’s reproductive ue: (1) features of physical appearance, such as full lips, clear skin, smooth skin, clear eyes, rous hair,good muscle tone,and body fat distribution; and (2) features of behavior,such as a” ( :118)

“ms with young, attractive, nubile women had sex with them frequently (Betzig, 1992). The Moroccan emperor Moulay Ismail the odthirsty, for example, acknowledged siring 888 children. His harem included 500 women. when a woman reached the age of thirty,she was banished from” ( :132)

“adison Avenue is somees charged with advancing a single arbitrary standard of beauty that everyone else must live o. This accusation is at least partially false. The standards of beauty, as we have seen, are not trary but rather embody reliable cues to fertility and reproductive value. A” ( :134)

“one study, after groups of men looked at photographs of either highly attractive men or women of average attractiveness, they were asked to evaluate their commitment to r current romantic partners (Kenrick et al., 1994). The men who had viewed pictures of active women thereafter judged their actual partners to be less attractive than did the men who viewed pictures of women who were average in attractiveness. They also rated themselves as committed to,less satisfied with,less serious about,and less close to their actual partners. P” ( :134)

“ozen women considered attractive by today’s measure. The presence of a relative abundance ttractive women, however, might reasonably induce a man t would decrease his commitment to his existing mate. Consider modern times. We carry with us the same evaluative mechanisms that evolved in ient times.

These images do not represent real women in our actual soc” ( :134)

“They discovered that when given a low budget and asked to allocate their mating dollars ac a number of mate attributes, men allocated a relatively large proportion of their budget to ph cal attractiveness and women allocated a relatively large proportion of their budget to resource precisely in line with the sex differences found in all the other studies of mate preferenc” ( :137)

“The varying budgets—low, medium, and high—are likely to show some parallels to i vidual differences in “mate value.” Those low in mate value have less choice, so they wan ensure adequate levels on the necessities of mating—for men, some minimum level of att tiveness; for women,some minimum level of resources and status. As mate value increases,p ple can afford to be choosier on a wider array of characterist” ( :137)

5. Women’s Long-Term Mating Strategies


“men, like weaverbirds, also prefer males with “nests” of various kinds.” ( :148)

“woman who preferred to mate with a relie man who was willing to commit to her would have had children who survived, thrived, and ltiplied. Over thousands of generations, a preference for men who showed signs of being ing and able to commit evolved in women, just as preferences for mates with adequate nests lved in weaverbirds. This preference solved key reproduction problems, just as food preferes solved key survival problems.” ( :148)

“e production of high levels of testosterone is known to comproe the human immune system. According to Johnston’s argument, only males who are quite lthy can “afford” to produce high levels of testosterone during their development. Less lthy males must suppress testosterone production,lest they compromise their already weaker mune systems. As a result, healthy males end up producing more testosterone and developing re rugged masculine-looking faces. If” ( :164)

“en together,these studies point to the importance of paternal qualities—a man’s interest and willingness to invest in,children—as critical to women’s selection of a long-term mate.” ( :168)

“In long-term mating, women prefer men who produce humor, whereas men prefer women are receptive to their hum” ( :169)

“short, when mating motives are “primed” by exposure to ng attractive women,a cascade of psychological shifts occurs in men such that they value and lay precisely what women want and hence what men need to succeed in mate competition.” ( :176)


6. Short-Term Sexual Strategies


“ng “Hi, I’ve b noticing you around town lately,and I find you very att tive. Would you have sex with me?” How would respond? If you are like 100 percent of the women in study, you would give an emphatic no. You would offended, insulted, or just plain puzzled by the requ But if you are like the men in that study, the odds are g that you would say yes—as did 75 percent of those (Clarke & Hatfield, 19″ ( :181)

“th. The hig monogamous gorilla females averaged only one male sex partner per birth. Human females w estimated to have 1.1 male sex partners per birth, or nearly 10 percent more sex partners t gorillas.

You uld be predicted not to sacrifice your own life for just one brother, because that would vioHamilton’s rule.

9. Cooperative Alliances


“ilkinson discovered that the “friends” ded to regurgitate blood more often when their friends were in dire need and close to starva- (e.g., thirteen hours from death) than when they were in mild need (e.g., two days from th). He also found that the starved bats who received help from their friends were more likely ive blood to those who had helped them in their time of need. In sum, vampire bats show all signs of having evolved reciprocal altruistic adaptations.” ( :280)
