|3||The characteristics that are universally attractive include,
but are not limited to, physical health, clear skin, and symmetry (right
& left side of the body having the same proportions). One additional
universal feature of sexual attraction is an aversion towards close genetic
relatives. See the notes to the beauty chapter (pp 153-172) for detailed
references on beauty universals.
Numerous studies have demonstrated that more symmetrical people are considered more attractive by others. See, for example: Perrett, D.I., D. Burt, D.M., I.S. Penton-Voak, K.J. Lee, D.A. Rowland, and R. Edwards. 1999. "Symmetry and human facial attractiveness." Evolution and Human Behavior 20:295-307. They found that, for males and females, when computer images were manipulated to increase the symmetry of the fac, the ratings of attractiveness also increased.
A related study, looking at men, also found that physical attractiveness was significantly correlated with symmetry. Interestingly, they also found that it wasn't even necessary to measure the symmetry of the man's face. In other words, men with asymmetrical fingers, feet, wrists, and elbows, have less attractive faces than men in whom these structures are more symmetrical. The data are in: Gangestad, S.W., R. Thornhill and R.A. Yeo. 1994. "Facial attractiveness, developmental stability, and fluctuating asymmetry." Ethology and Sociobiology 15:73-85.
And finally, Mealey et al. did an interesting study of twins, in which symmetry and attractiveness were measured in each. As would have been predicted by the studies cited above, the more symmetrical of the twins were rated as significantly more attractive than their less symmetrical co-twin. The study is in: Mealey L., R. Bridgstock, and G.C. Townsend. 1999. "Symmetry and perceived facial attractiveness: A monozygotic co-twin comparison." Journal of Personality and Social Psychology 76:151-158.

clear where all of the studies above are pointing and, indeed, one study
showed it to be true that women whose partners were more symmetrical reported
more orgasms during sex than did women with less symmetrical partners.
The study is: Thornhill, R., S.W. Gangestad, and R. Comer. 1995. "Human
female orgasm and mate fluctuating asymmetry." Animal Behavior
An important review that covered an impressively broad array of animal species (including both vertebrates and invertebrates), documented a consistent relationship between symmetry and nearly every important component of fitness, including: parasitism, fecundity, growth rate, survival, and metabolic efficiency. The study is Thornhill, R. and A.P. Moller. 1997. "Developmental stability, disease, and medicine." Biological Reviews of the Cambridge Philosophical Society 72:497-548.
For example: barn swallows showed increased asymmetry following infection with a parasitic mite, reindeer treated with an anti-parasite medication during antler development had more symmetrical antlers, and fruit flies infected with nematode parasites during development become less symmetrical as adults. These data are presented in: Moller, A.P. 1992. "Parasites differentially increase the degree of fluctuating asymmetry in secondary sexual characters.ƒ Journal of Evolutionary Biology 5:691-699, (barn swallows); Folstad, I., P. Arneberg, and A.J. Karter. 1996. "Antlers and parasites." Oecologia 105:556-558, (reindeer); and Polak, M. 1993. "Parasites increase fluctuating asymmetry of male Drosophila nigrospiracula: implications for sexual selection." Genetica 89:255-265, (fruit flies).
studies cited above, it's not clear whether the causal link between
parasites and symmetry is one way or two. In and interesting study in
house flies, individuals that were more asymmetric proved to be susceptible
to infection when exposed to a fungus. The study is in: Moller, A.P.
1995. "Sexual selection, viability selection and developmental
stability in the domestic fly, Musca domestica." Evolution 50:746-752.

"Effect of moderate weight loss on ovarian function assessed by salivary progesterone measurements." American Journal of Human Biology 2:303-12. In this study, the same subjects were followed over multiple months and it turned out that women who were not dieting ovulated during every one of their cycles, while dieters, on the other hand, (who were losing weight at a rate of about four pounds per month) failed to ovulate in about 40% of their cycles.
interesting and carefully-controlled study of the effects of moderate
exercise on fertility showed that women running about 12 miles per week

See page 240, for instance: "Red squirrels (Tamiasciurus hudonicus), common inhabitants of coniferous forests throughout much of North America, and the closely related Douglas squirrel (T. douglasii) of the Pacific Northwest are among the most thoroughly studied of food-hoarding mammals . . . Red squirrels begin collecting and storing cones in late July or early August and continue for 4-8 weeks … Clarke (1939) estimated that red squirrels can collect and store about 1,000 red pine (Pinus resinosa) cones in a day, but they clip and store the large cones of limber pine (P. flexilis) at rates of only about twenty-nine to thirty-two cones per day (Benkman, Balda, and Smith 1984). … Middens usually contain 2-4 bushels (70-141) of cones, but instances of 8-15 bushels (282-528 l) being taken by cone collectors have been reported (Cox 1911; Korstian and Baker 1925; Yeager 1937; Baldwin 1942). M.C. Smith (1968) estimated that red squirrels stored between 12,000 and 16,000 white spruce (Picea glauca) cones in a 6-week harvest period in interior Alaska. Gurnell (1984) found a mean of 2,187 lodgepole pine cones in nine middens (range = 280-4,360 cones per midden). . ."
"Besides cones, red squirrels store various nuts, seeds, fruits, and some meat. Nuts stored include walnuts, hickory nuts (Layne 1954), chestnuts (Audobon and Bachman 1846, cited by Hatt 1929), beechnuts (Klugh 1927), and hazelnuts (Mailliard 1931). … Burton (1930) attributed to red squirrels accumulations of boxelder (Acer negundo) samaras found at the bases of trees, in hollow trunks, and in the crotches of tree branches. One of these caches contained more than a bushel (35 l) of seeds."

Discussion of the role of social security in alleviating poverty among the elderly, http://www.ssa.gov/history/early.html
"Following the outbreak of the Great Depression, poverty among the elderly grew dramatically. The best estimates are that in 1934 over half of the elderly in America lacked sufficient income to be self-supporting. Despite this, state welfare pensions for the elderly were practically non-existent before 1930. A spurt of pension legislation was passed in the years immediately prior to passage of the Social Security Act, so that 30 states had some form of old-age pension program by 1935. However, these programs were generally inadequate and ineffective. Only about 3% of the elderly were actually receiving benefits under these states plans, and the average benefit amount was about 65 cents a day."

Japan's problems with oversaving were described in The Wall Street Journal on May 17, 2000
Japan is the first major developed country since World War II to confront the 'paradox of thrift,' the condition John Maynard Keynes worried about, where bad times lead individuals to save more, suppressing overall demand and making a country even worse off.
So the Japanese government nudges its citizens to live it up. The Finance Ministry, concerned that families would simply tuck away a recent $500-a-household income-tax cut, launched a media blitz to advise people on how to spend the money.
A cartoon in a magazine ad shows a father excitedly reading about the cuts in the newspaper, inspiring his two young kids to dream of cake and candy and his blushing wife to ask for a blouse. A poster plastered in subway stations pictures an aerial shot of a crammed neighborhood with words emanating from the homes. "I'll drink a toast with fine wine," says one. "I'll finally buy those golf clubs," says another. One implores: "Let's spend it all at once!"

Obesity is a clinical term that is revised from time to time. According to the Centers for Disease Control, an individual is "overweight" if they have a Body Mass Index (BMI) greater than or equal to 25. This means that 54.6 % of Americans are overweight. A BMI greater than or equal to 30 is considered obese. This means that 22.6 % of the population are obese.

John Daly discussed his ongoing battle over trying to stay sober with ESPN Golf Online news services September 23, 1999 and in a related interview with Golf World Magazine. Excerpts.
NEW YORK -- John Daly is drinking and gambling again, not sure where
it will lead but offering no regrets for losing an endorsement with
Callaway Golf that had been his primary source of income. "It's
sad, but I think it's great to be free," Daly told Golf World magazine
Daly said "Basically, it (trying to stay sober) had taken over my life, and I was miserable. It's like I've said before, there's no way I'd never drink again."
Daly's five-year deal with Callaway, signed after he left rehab in April 1997, included a provision that he not drink or gamble. Chairman Ely Callaway offered to send Daly to an addictions specialist nearly two weeks ago. Daly got to the undisclosed clinic and left. "The people were nice," Daly told Golf World. "But it just wasn't for me." Callaway said he had no choice but to drop Daly, who stood to earn about $3 million over the final two years of the contract.
Asked by the magazine why he continued to gamble even though he lost
an estimated $12 million from 1993 to 1996, Daly said, "I love
the action. I just love it."

is difficult to get an accurate count of just how many high school students
take steroids and so estimates can vary a bit. The data we cite are from
the National Institute of Drug Abuse (http://www.nida.nih.gov/Infofax/steroids.html).
they reported in 1997 that 175,000 high school girls and 325,000 high school
boys used steroids.
steroids can indeed increase an individual's muscle mass. According to The
National Clearinghouse for Alcohol and Drug Information: "Anabolic
steroids are drugs derived from the male sex hormone, testosterone. They
promote muscle growth and increase lean body mass." See: http://www.health.org/pubs/qdocs/steroid/stereffects.htm

Are dopamine receptor levels related to alcoholism? This is still a pretty controversial question. Examination of DNA samples from the brains of corpses of thirty-five alcoholics and thirty-five non-alcoholics revealed that a variant of the gene for a specific type of dopamine receptor (D2) was present in 69% of the alcoholics but only 20% of the non-alcoholics. These date are from: Noble, E.P., P.J. Sheridan, A. Montgomery, T. Ritchie, P. Jagadeeswaran, H. Nogami, A.H. Briggs, and J.B. Cohn. 1990. "Allelic association of the D2 dopamine receptor gene in alcoholism." Journal of the American Medical Association 263:2055-60; and also discussed in: Noble, E.P. and K. Blum. 1991. "The dopamine D2 receptor gene and alcoholism" (letter to the editor). Journal of the American Medical Association 265:2667.
Their claim is that this variant, called the A1 allele, results in fewer D2 receptors in the brain (See Noble, E.P., K. Blum, T. Ritchie, A. Montgomery, and P.J. Sheridan, P.J. 1991. "Allelic association of the D2 dopamine receptor gene with receptor binding characteristics in alcoholism." Archives of General Psychiatry 48:648-654.) In this paper, the second section of table 3, page 652, clearly shows that the number of binding sites is significantly correlated with which allele a person carries.
On the front
page of the New York Times, however, a team from the National Institute
on Alcohol Abuse and Alcoholism announced that it did not find any difference
between alcoholics and non-alcoholics in the frequency of the A1 allele.
Both sides are continuing to explore this issue.
Also controversial is the question of the link between having a gene for dopamine receptors and smoking addiction. But see: Lerman, C., N.E. Caporaso, J. Audrain, D. Main, E.D. Bowman, B. Lockshin, N.R. Boyd, and P.G. Shields. 1999. "Evidence suggesting the role of specific genetic factors in cigarette smoking." Health Psychology 18:14-20. This was a twin study showing evidence that the SLC6A3 (dopamine receptor) gene influenced smoking initiation and nicotine dependence.
study then proposed that that individuals with a particular type of dopamine
receptor gene have altered dopamine transmission, reducing their need
for novelty and reward by external stimuli (such as cigarettes). See:

U.S. gambling statistics are available in many places. The most comprehensive is the 1999 report of the National Gambling Impact Study Commissionavailable online: http://www.ngisc.gov/. The Economist wrote a more readable article on U.S. gambling in June 1998, it's highlights:
"Legalised gambling is now permitted in 47 states and the District of Columbia, generating more than $50 billion in gross revenues (dollars wagered minus payouts). Gambling expenditures as a percentage of personal income more than doubled between 1974 and 1997, from 0.3% to 0.74%. Americans now spend more on various wagers than they do on theme parks, video games, spectator sports and movie tickets combined (see chart). Government is far more than an observer in all this. Revenue from state lotteries climbed from $2 billion in 1973 to $34 billion in 1997. The states spent $400m advertising such games, in some cases targeting poor districts. Tribal casinos take in another $7 billion."
In the lottery, there are 51 balls, each with a different number painted on. They go from 1 to 51. Six balls are going to be pulled out of a bin. In order to win the jackpot, you must choose all six numbers.

Jim Clark stories from, Lewis, Michael. 1999. The New New Thing. Norton.
I reminded Clark that he had said that once he became a real, after-tax billionaire he'd retire. He now said, without missing a beat: "I just want to make more money than Larry Ellison. Then I'll stop." This was news. I pointed out that he'd never before mentioned this ambition. "I just want to have more money than Larry Ellison," he said again. "I don't know why. But once I have more money than Larry Ellison I'll be satisfied."
Larry Ellison, the C.E.O. of Oracle, the biggest software company in the valley, was worth about $9 billion; Clark was, just then, worth a bit more than $3 billion. On the other hand, Ellison's wealth was completely tied up in Oracle stock, which had mostly missed out on the Internet boom. At the rate Clark's wealth was growing he'd pass Ellison within six months. I pointed this out and asked the obvious question:
"What happens after you have more than Larry Ellison? Would you want to have more money than, say, Bill Gates?... Oh, no," Clark said, waving my question to the side of the room where the ridiculous ideas gather to commiserate with one another. "That'll never happen." A few minutes later, after the conversation had turned to other matters, he came clean. "You know," he said, "just for one moment, I would kind of like to have the most. Just for one tiny moment."

Seahorses as Mr. Moms.
Many books suggest that seahorses display sex role reversals similar to that of moorhens; recent data suggest that this may not be true, at least for some species. Note: seahorses are fish complete with fins and gills.
The story until recently focused on the high level of male seahorse investment in offspring. The seahorse mating system has females produce the eggs then transfer them to a pouch in the male. The male carries the offspring inside of him in a form of prenancy and eventually gives birth. The link has some interesting photos of seahorses and contains a review of the literature.
Recent data suggest that male seahorses do not invest more in offspring than do female seahorses. In this new view, the male investment in offspring is still considered high, but females invest significant resources in egg production and females (at least of some species) visit males during the males "pregnancy".
If male seahorse investment in offspring is lower than female investment in offspring, then the prediction is that seahorses will display the more common sex differences in behavior. Specifically, if females invest more, the females should be more choosy in picking mates than males, and males will be more competitive. Several papers find that male-female relationships are, in the author's words, "conventional".
Vincent, A.C. 1994. "Seahorses exhibit conventional sex roles in mating competition, despite male pregnancy." Behaviour : 128-135.
As summarized in the science news Vincent finds:
More recent work confirms this conventional view of seahorse sex roles; female seahorses (species Hippocampus zosterae) have lower potential reproductive rates than males, and females are more reluctant to mate than males:

Among the Sambia, adult males are husbands, fathers, and warriors who must always be prepared for war. They do not as adults engage in homosexual practices and in fact look down upon the occasional adult male who does so, at least one who does so habitually. All of these very masculine, heterosexual males, however, have spent years engaging in homosexual acts required of them as preadult initiates, during which time they avoided women and learned to be antagonist toward them."|

The British study of cuckoldry was reported widely in the media (see, for instance, the Sunday London Times excerpt below.) It should be noted that these data come from individuals that came to a laboratory that does paternity testing and, consequently, must be assumed to have more reason than average to suspect cuckoldry.

They also report here that males respond to increased risk that the female has had sex with another male (with the risk assessed as a function of the percent time they've spent together since their last copulation) by increasing the number of sperm inseminated. When couples are together for 100% of this time, there are an average of 389 million sperm per ejaculate. When they are together for only 5% of the time, the number of sperm per ejaculate nearly doubles, to 712 million.|

"In the chimpanzee, territoriality functions not only to repel intruders from the home range, but sometimes to injure or eliminate them; not only to defend the existing home range and its resources, but to enlarge it opportunistically at the expense of weaker neighbors; not only to protect the female resources of a community, but to actively and aggressively recruit new sexual partners from neighboring social groups." -- p 528
Chimpanzee aggression and its implications for human society are explored in, Wrangham, Richard and Dale Peterson. 1996. Demonic Males. Houghton Mifflin.
"Defense of territory is widespread among many species, but the Kasekela chimpanzees were doing more than defending. They didn't wait to be alerted to the presence of intruders. Sometimes they moved right through border zones and penetrated half a mile or more into neighboring land. They did no feeding on these ventures. And three times I saw them attack lone neighbors. So they seemed to be looking for encounters in the neighboring range. These expeditions were different from mere defense, or even border patrols. These were raids." --p 13

Sugar content of natural and manufactured foods was observed in, Kugel, Allan. 1999. Evolution and the Utility Self-Subversion Effect. Manuscript. Kugel's manuscript online.
The key diagram is on page 7 in this paper. It it, sugar content is listed by percent weight.
Bananas can be seen as the highest of the natural foods listed, with about 14% sugar content by weight (reading from a graph).
Oranges are just under 10%.
Among manufactured foods listed we have granola cereal at 30%, Sugar Smacks cereal at over 55%, candy "(typical)" also at over 50% and jam-filled sponge cake at 50%.
One caveat to these numbers: the lower water content of the manufactured products listed may be exaggerating the differences

Walter Mischel conducted dozens of experiments on deferral of gratification including the marshmallow studies. A nice review of this work is, Mischel, Walter, Yuichi Shoda and Monica Rodriguez. 1989. "Delay of Gratification in Children." Science, 244: 933-938. Professor Mischel's web site
Mischel et al. report: "After children understand the contingency, they are left on their own during the delay period while their behavior is observed unobtrusively, and the duration of their delay is recorded until they terminate or the experimenter returns (typically after 15 minutes).
They also state that: "A recent follow-up study of a sample of these children found that those who had waited longer in this situation at 4 years of age were described more than 10 years later by their parents as adolescents who were more academically and socially comptent than their peers and more able to copy with frustration and resist tempation."
And finally: "seconds of delay time in preschool also were significantly related to their Scholastic Aptitude Test (SAT) scores when they applied to college."
Additional experimental investigations of delayed gratification in children are reported in Loewenstein, G. and J. Elster, Eds. (1992). Choice over Time. New York, Russell Sage Foundation.
For detailed descriptions of the methods used in the deferred gratification studies, see also: Shoda, Y., Mischel, W. and Peake, P.K. (1990) Predicting Adolescent Cognitive and Self-Regulatory Competencies from Preschool Delay of Gratification: Identifying Diagnostic Conditions. Developmental Psych 26(6): 978-986.
In this study, children (mean age 4 years and 4 months) were tested with marshmallows, pretzel sticks, or poker chips, depending on which the child picked. They were told that the researcher would leave the room, and when he returned the kid could have two marshmallows (or pretzels, or poker chips). The child could ring a bell at any time to bring the researcher back, but if s/he rang the bell s/he could only have one marshmallow. Their mean waiting time was 512.8 sec, with a standard deviation of 368.7 seconds (with no difference according to sex).
The researchers also varied whether the reward was exposed, and whether a tactic of self-distraction was suggested. They would say, for instance: "why don't you think about something fun we could do afterwards while you wait." The unsuggested condition was described as "spontaneous ideation" while a suggested distraction was "suggested ideation" Altogether, they had four possible experimental conditions:
Of these: only the Exposed/Spontaneous differences in delay time in preschoolers was predictive of later traits. The follow up was done around age 18, via parental questionnaires and SAT scores. Questions they asked included: How likely is your child to be sidetracked by minor setbacks? When motivated, how capable is your child of exhibiting self-control in tempting situations? Is planful, thinks ahead? 12 out of 14 were significantly correlated with delay times in these children as preschoolers, but again only under Exp/Spont conditions. SAT Verbal and SAT Math were both correlated as well (correlation = 0.42, p<.05 and .57, p<.001, respectively).
The researchers hypothesized that the exposed/spontaneous ideation conditions are more predictive because intelligent, patient, motivated kids are more likely to develop their own strategies for self-distraction while they wait. When this strategy is suggested/facilitated, or when the rewards are unexposed (presumably providing less of a temptation) the difference in abilities of kids to self-distract is obscured.
A recent paper reported several studies investigating chimpanzee learning:
Study 1 used food: One hand has three raisins, while the other has 5. The researchers tried to train the chimpanzees to chose the smaller of the two quantities in order to receive the largest. After hundreds and hundreds of trials, there was no improvement!
Study 2, on the other hand, used "symbols." Chimpazneess were taught that one pebble represented one raisin. Then chimpanzees were then shown different amounts in different hands with the same rule: pick the smallest number of rocks in order to receive the larger number. Under these condistions the chimpanzees can learn (and relatively quickly).
In Study 3, the researchers used arabic numbers since several of these same chimpanzees know the arabic numerals through about 9. Again, different amounts of food were represented by numbers, with the champanzees having to pick smaller number in order to get the larger payoffg. Again the chimps quickly learn to perform well.

"Generally, he who occupies the field of battle first and awaits his enemy is at ease, and he who comes later to the scene and rushes into the fight is weary. And, therefore, those skilled in war bring the enemy to the field of battle and are not brought there by him. One able to make the enemy come of his own accord does so by offering him some advantage. And one able to stop him from coming does so by preventing him. Thus, when the enemy is at ease, be able to tire him, when well fed, to starve him, when at rest to make him move." --p. 96, chapter 6.
