Napoleon Chagnon: Blood is their Argument“‘It’s almost always for revenge. Blood is their argument. The Yanomamö will always attempt to avenge the death of a kinsman. It may take them a long time, and when the tables are turned on the guys that did it, like they get too small as a group, then it may appear to be a preemptive strike, but it has some historical roots. It’s almost never a case where they attack another Yanomamö village preemptively for no reason at all. It’s usually a consequence of some previous argument.’” – via habitable worlds: Darwin’s Dangerous Clan. see also Historical Reality: Infanticide vs Abortion @occam’s razor.

Either way, Feldman said, the urge to make oneself likable and competent was a powerful motivator.”

(note: comments do not require an email. cute overload alert! don’t say you weren’t warned.)

over the weekend, one of my younger first cousins once removed declared that he absolutely, definitely will be a fireman when he grows up (he’s three). his father, one of my in-laws, (half-)jokingly said that, no, you’ll be a lawyer or a doctor or a professor. i chimed in with: “get into genetics, kid. that’s where all the money will be.” (heh! as if i would know.)

my cousin-in-law responded: “genetics? but that’s unethical.” this from a man with a marketing degree. (~_^)

i have to admit i was pretty flummoxed and didn’t really know how to respond or even where to start. our follow up discussion was brief so i didn’t get a satisfactory explanation as to what’s “unethical” about “genetics,” but i got to wondering what the rest of america thinks. thankfully, they’re not so skeptical:

Survey finds wide public support for nationwide study of genes, environment and lifestyle
Nov 12, 2008

Four in five Americans support the idea of a nationwide study to investigate the interactions of genes, environment and lifestyle, and three in five say they would be willing to take part in such a study, according to a survey released today. The research was conducted by the Genetics & Public Policy Center at Johns Hopkins University with funding from the National Human Genome Research Institute (NHGRI) of the National Institutes of Health (NIH)….

“Our survey found that widespread support exists in the general public for a large, genetic cohort study. What’s more, we found little variation in that support among different demographic groups,” said David Kaufman, Ph.D., lead author of the paper and project director at the Genetics & Public Policy Center, which is located in Washington….

The online survey of 4,659 U.S. adults was conducted between December 2007 and January 2008. When asked about their support for and willingness to participate in a large genetic cohort study, 84 percent of respondents supported the study and 60 percent indicated they would definitely or probably participate in such a study if asked.

Survey respondents were carefully selected to reflect the demographic makeup of the United States. No significant differences in support or willingness to participate were observed between whites, Hispanics, African Americans and Asians. American Indian and Alaska Native respondents expressed less support for the study (65 percent), but were just as likely to be willing to participate (63 percent) as other respondents….

the pew folks also conducted a “town hall meeting” about genetics in 2008 — a set of five focus group sessions held around the country. from the report [pg. 11]:

“Participants were asked to consider what types of research should and should not be done with the information collected by the proposed study. Research aimed at curing disease was commonly cited as acceptable, and some participants named conditions such as cancer, birth defects, and diabetes….

“Human cloning was cited in every town hall as an unacceptable use of the proposed biobank, although in one case participants differentiated between reproductive cloning (unacceptable) and cloning aimed at regenerating organs or otherwise curing disease (acceptable). Participants frequently named research aimed at altering humans or creating ‘designer babies’ as unacceptable. Another area of concern was ‘things that point out differences between gender, or race, or anything like that that people use to discriminate.’ Other areas mentioned included weapons development, intelligence, alcoholism, and sexual orientation….”

so a lot of americans don’t like the idea of cloning. personally, i’m looking forward to being able to clone myself. i mean, how great a world would it be with more MEs in it? (~_^) and why should bacteria and some lizards have all the fun anyways?

and a lot of americans don’t like “designer babies” either. the funny thing is, of course, that they don’t realize that that’s what they’re aiming for when they look for that perfect someone to marry, i.e. kids to match their heart’s desire. in fact, a lot of americans don’t like anything that smacks of eugenics. i guess that’s not too surprising at this point in time.

at least the majority haven’t written off the whole discipline of genetics as “unethical” though.

from the christian science monitor:

“Mexico’s ‘temporary’ marriages: till death – or two years – do us part”

“Mexico City is studying a plan to introduce ‘temporary’ marriage licenses – letting couples choose after two years to split or renew the license for life – in an effort to mitigate the effects of divorce….

“The left-leaning assembly is studying a new initiative to introduce temporary marriage licenses that would expire after two years if the couple so desires.

“The proposal, intended to reduce the bureaucratic costs and emotional toll of divorce, has garnered as many fans as foes: Some see it as a pragmatic alternative, while others, including the Roman Catholic Church, see it as an attack on family values. It comes as Mexico grapples with its own culture war in the world’s second-largest Catholic country.

“‘The centrality of family in Mexico is changing,’ says Norma Ojeda, a sociologist at the San Diego State University who has studied the evolution of marriage in Mexico since the 1970s. ‘That is something that is part of a global social change in many countries.’

“To its authors, the proposal reflects social changes in Mexico City, where they say most divorces occur in the first two years. If after two years, couples decide to until ‘death do us part,’ they can renew their licenses. If not, the proposal specifies how children and property are handled.

“‘The proposal is, when the two-year period is up, if the relationship is not stable or harmonious, the contract simply ends,’ Leonel Luna, the assemblyman who co-wrote the bill, told Reuters. ‘You wouldn’t have to go through the tortuous process of divorce.’”

plenty of societies have or had laws providing for temporary marriages. many muslim societies (primarily shi’a ones?) have a temporary form of marriage known as nikah mut’ah. it can be used as a way of covering up prostitution (“get yer four hour marriages!”), but that’s not the only reason the practice exists.

temporary marriage was also an option amongst the early medieval irish [pg. 302]:

“The adaltrach [one type of wife in early medieval ireland] may not have brought much property at all, since in many cases, the primary intention of the union was merely to achieve social acceptance of a sexual relationship and its progeny. Another goal was to set up a temporary working relationship, in which the man supplied the farm and the woman supplied the labor. Where CL [Cain Lanamna, 'the law of marriage'] discusses spouses who were brought in to live on another’s farm, it emphasized the labor aspect of the spouse’s relationship; this was as true of a man supported on a woman’s farm as it was of a woman supported on a man’s property. CL #28 depicts the woman in this case as keeping half her handiwork, and one-ninth of the milk, corn and bacon produced during the time the couple lived together. The relationship envisaged as likely to end at Beltene, the spring festival of May 1, which was also the time many women traditionally moved with the livestock to the summer pastures. The departing woman was supposed to have ‘a sack (of produce) for every month’ she had spent on the man’s farm.”

the thing is, tho, that no society with temporary marriages ever invented things like science or succeeded with liberal democracy. those seem, for complex reasons, to go along with strong monogamy (not to mention a relatively high iq).

mating practices affect the patterns of genetic relatedness amongst the members in any given society; and those patterns, in turn, affect the historical and evolutionary trajectories of societies.

(note: comments do not require an email. strong monogamy.)
