A Family Tree in Every Gene - 0 views

  • Who speaks of "racial stocks" anymore? After all, to do so would be to speak of something that many scientists and scholars say does not exist. If modern anthropologists mention the concept of race, it is invariably only to warn against and dismiss it. Likewise many geneticists. "Race is social concept, not a scientific one," according to Dr. Craig Venter—and he should know, since he was first to sequence the human genome.
  • But now, perhaps, that is about to change
  • The dominance of the social construct theory can be traced to a 1972 article by Dr. Richard Lewontin, a Harvard geneticist, who wrote that most human genetic variation can be found within any given "race." If one looked at genes rather than faces, he claimed, the difference between an African and a European would be scarcely greater than the difference between any two Europeans.

  • Three decades later, it seems that Dr. Lewontin's facts were correct, and have been abundantly confirmed by ever better techniques of detecting genetic variety. His reasoning, however, was wrong. His error was an elementary one, but such was the appeal of his argument that it was only a couple of years ago that a Cambridge University statistician, A. W. F. Edwards, put his finger on it.
  • Genetic variants that aren't written on our faces, but that can be detected only in the genome, show similar correlations. It is these correlations that Dr. Lewontin seems to have ignored. In essence, he looked at one gene at a time and failed to see races. But if many—a few hundred—variable genes are considered simultaneously, then it is very easy to do so. Indeed, a 2002 study by scientists at the University of Southern California and Stanford showed that if a sample of people from around the world are sorted by computer into five groups on the basis of genetic similarity, the groups that emerge are native to Europe, East Asia, Africa, America and Australasia—more or less the major races of traditional anthropology.

    "A Family Tree in Every Gene By Armand Marie Leroi Published on: Jun 07, 2006 Armand Marie Leroi, an evolutionary developmental biologist at Imperial College in London, is the author of Mutants: On Genetic Variety and the Human Body." This Article is a fairly sensible, nuanced, defense of the race concept based on recent genetic analyses of hundreds of genetic variables at a time.

    This is a short list of good points to be made about Genetics and the concept of race.  I find that it is often difficult for students to wrap their heads around genetic variation and race.  I will try my best to explain it in the coming week.

Movement Against Patenting of Seeds in India: Negative Effects of Patenting Seeds - 0 views

  •  
    "As of 2010, six biotech and chemical companies owned 77 percent of the world's patents on living organisms. These companies were DuPont, BASF, Monsanto, Syngenta, Bayer and Dow. Only 9 percent of similar patents were in the public sector. These patents extend beyond the genetic material of the seeds themselves, and also claim potential ownership of the crops they produce, and even to the food and feed products produced after harvest."

Imminent Anthropological Scandal - 0 views

  • The focus of the scandal is the long-term project for study of the Yanomami of Venezuela organized by James Neel, the human geneticist, in which Napoleon Chagnon, Timothy Asch, and numerous other anthropologists took part. The French anthropologist Jacques Lizot, who also works with the Yanomami but is not part of Neel- Chagnon project, also figures in a different scandalous capacity.
  • One of Tierney's more startling revelations is that the whole Yanomami project was an outgrowth and continuation of the Atomic Energy Comissions secret program of experiments on human subjects James Neel, the originator and director of the project, was part of the medical and genetic research team attached to the Atomic Energy Commission since the days of the Manhattan Project.
  • Tierney presents convincing evidence that Neel and Chagnon, on their trip to the Yanomami in 1968, greatly exacerbated, and probably started, the epidemic of measles that killed "hundreds, perhaps thousands" (Tierney's language-the exact figure will never be known) of Yanomami. The epidemic appears to have been caused, or at least worsened and more widely spread, by a campaign of vaccination carried out by the research team, which used a virulent vaccine (Edmonson B) that had been counter-indicated by medical experts for use on isolated populations with no prior exposure to measles exactly the Yanomami situation). Even among populations with prior contact and consequent partial genetic immunity to measles, the vaccine was supposed to be used only with supportive injections of gamma globulin.

What are the major accusations or questions of debate concerning "Darkness in El Dorado?" - 70 views

The major issue to me in this article was the fact that many of Neel and Chagnon's findings were very loosely based on fact when they were further explored. Other anthropologists had studied many ...

Darkness in El Dorado - 0 views

  • Hence Neel’s terrible experiments on the Yanomami, in a kind of grim downgrade of the Malthusian ethics of “Survivor.” He wanted to disprove the vulnerability of small, isolated groups to epidemics, seeking to show that though a disease such as measles might wreak awful havoc, his alpha-dominated males would be better adapted to evolve genetic immunity to these “contact” diseases. Many might die but the survivors would be of ever more superior stock. In their letter to the head of the Anthropological Association Turner and his colleague Sponsel write carefully that “Tierney’s well-documented account, in its entirety, strongly supports the conclusion that the epidemic was in all probability deliberately caused as an experiment designed to produce scientific support for Neel’s eugenic theory.”
