race culture racism genetics adaptation evolution

  • 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.

evolution human thought food diet

shared by J Scott Hill on 29 Jan 13 - No Cached
  • Our earliest ancestors ate their food raw — fruit, leaves, maybe some nuts. When they ventured down onto land, they added things like underground tubers, roots and berries.
  • "You can't have a large brain and big guts at the same time," explains Leslie Aiello, an anthropologist and director of the Wenner-Gren Foundation in New York City, which funds research on evolution. Digestion, she says, was the energy-hog of our primate ancestor's body. The brain was the poor stepsister who got the leftovers.
  • "What we think is that this dietary change around 2.3 million years ago was one of the major significant factors in the evolution of our own species," Aiello says.

  • cut marks on animal bones appeared
  • that could have been made only by a sharp tool.
  • But Aiello's favorite clue is somewhat ickier — it's a tapeworm. "The closest relative of human tapeworms are tapeworms that affect African hyenas and wild dogs," she says.
  • Besides better taste, cooked food had other benefits — cooking killed some pathogens on food.
  • It breaks up the long protein chains, and that makes them easier for stomach enzymes to digest. "
  • collagen is very hard to digest. But if you heat it, it turns to jelly."
  • starchy foods like turnips, cooking gelatinizes the tough starch granules and makes them easier to digest too. Even just softening food — which cooking does — makes it more digestible. In the end, you get more energy out of the food.

    "However, some important points are mistaken or missing. Contrary to Alan Fix, research on Yanomami began not in the 1960s but as early as 1800. Now there are more than 60 books, albeit of widely varying quality, on aspects of Yanomami. Sufficient literature exists to recognize a field of specializationYanomami Studies or Yanomamology. It is possible to identify points of agreement and disagreement among the numerous and diverse writers who have published on Yanomami and draw conclusions" "None of some 60 books previously published on the Yanomami ever drew attention to the violations of professional ethics and abuses of human rights by anthropologists in the ways and to the extent that Tierney does. Not one of those books was subjected to a panel discussion and open forum at any AAA convention, any forum in a journal like CA, investigations in three countries, discussions in international media and cyberspace, etc" "Tierney exposed the ugliest affair in the entire history of anthropology. It cannot be summarily dismissed by a vocal minority as simply a matter of personal animosities, turf war, postmodernist critique of science or scientism, objectivist versus activist, differing interpretations of Yanomami aggression, sensationalist or tabloid journalism, etc. As Susan Lindee recognizes and contrary to Raymond Hames, not all of the fundamental claims made by Tierney have been discussed, let alone refuted."

Who's Afraid of the Big Bad Whorf? Crosslinguistic Differences in Temporal Language and... - 0 views

  • The idea that language shapes the way we think, often associated with Benjamin Whorf, has long been decried as not only wrong but also fundamentally wrong-headed.
  • which language influences nonlinguistic cognition, particularly in the domain of time
  • [T]he famous Sapir-Whorf hypothesis of linguistic determinism, stating that people's thoughts are determined by the categories made available by their language, and its weaker version, linguistic relativity, that differences among languages cause differences in the thoughts of their speakers […] is wrong, all wrong. (p. 57)
  • ...9 more annotations...
  • The idea that thought is the same as language is an example of what can be called a conventional absurdity[
  • The idea that language shapes thinking seemed plausible when scientists were in the dark about how thinking works, or even how to study it. Now that scientists know how to think about thinking, there is less of a temptation to equate[thinking]with language. (pp. 58–59, italics added)
  • Experimental work since Whorf's time has suffered several additional problems. Pinker noted that some apparent behavioral differences between language groups have turned out to be artifacts of clumsy translation.
  • Chinese speakers are less capable of reasoning counterfactually than English speakers because Chinese lacks subjunctives, which serve as counterfactual markers in English
  • The Orwellian idea that people think (mostly or entirely) in the medium of natural language, and therefore that language can be equated with thought, is unsupported empirically and is also problematic in principle, given what is known about language and about thought
  • Languages differ in the extent to which they describe duration in terms of distance as opposed to amount of substance.
  • Is this conflation of distance and duration universal to humans, or does it depend in part on the conflation of distance and duration in language?
  • Why should we continue to do Whorfian research? One possible reason is that cataloging crosslinguistic cognitive differences could be a step toward charting the boundaries of human biological and cultural diversity
  • crosslinguistic cognitive differences could be tools for investigating how thinking works and, in particular, for investigating the role of experience in the acquisition and representation of knowledge: If people who talk differently form correspondingly different mental representations as a consequence, then mental representations must depend, in part, on these aspects of linguistic experience. If discovering the origin and structure of our mental representations is the goal, then crosslinguistic cognitive differences can be informative even if they are subtle and even if their effects are largely unconscious. Whether or not they correspond to radical differences in speakers' conscious experiences of the world, Whorfian effects can have profound implications for the study of mental representation.

The Worst Mistake in the History of the Human Race - 5 views

    The quote, "we're better off in almost every respect than people of the Middle Ages, who in turn had it easier than cavemen, who in turn were better off than apes. Just count our advantages" really caught my attention right away because it can be debated. Are we really better off now than the people and animals before us? Although we do have more means of being able to obtain necessary things we need to survive, these advances have also caused many problems within our society today, mostly, in my opinion, due to technology, which is then related to agriculture.

  • n his classic work The Gift, Mauss argued that gifts are never "free". Rather, human history is full of examples that gifts give rise to reciprocal exchange. The famous question that drove his inquiry into the anthropology of the gift was: "What power resides in the object given that causes its recipient to pay it back?" (1990:3). The answer is simple: the gift is a "total prestation", imbued with "spiritual mechanisms", engaging the honour of both giver and receiver (the term "total prestation" or "total social fact" (fait social total) was coined by his student Maurice Leenhardt after Durkheim's social fact).
  • The giver does not merely give an object but also part of himself, for the object is indissolubly tied to the giver: "the objects are never completely separated from the men who exchange them" (1990:31). Because of this bond between giver and gift, the act of giving creates a social bond with an obligation to reciprocate on part of the recipient. To not reciprocate means to lose honour and status, but the spiritual implications can be even worse: in Polynesia, failure to reciprocate means to lose mana, one's spiritual source of authority and wealth.
  • In a gift economy, however, the objects that are given are inalienated from the givers; they are "loaned rather than sold and ceded". It is the fact that the identity of the giver is invariably bound up with the object given that causes the gift to have a power which compels the recipient to reciprocate. Because gifts are inalienable they must be returned; the act of giving creates a gift-debt that has to be repaid

ethics AAA research

shared by J Scott Hill on 07 Feb 13 - No Cached
  • Approved February 2009 I. Preamble Anthropological researchers, teachers and practitioners are members of many different communities, each with its own moral rules or codes of ethics. Anthropologists have moral obligations as members of other groups, such as the family, religion, and community, as well as the profession. They also have obligations to the scholarly discipline, to the wider society and culture, and to the human species, other species, and the environment. Furthermore, fieldworkers may develop close relationships with persons or animals with whom they work, generating an additional level of ethical considerations. In a field of such complex involvements and obligations, it is inevitable that misunderstandings, conflicts, and the need to make choices among apparently incompatible values will arise. Anthropologists are responsible for grappling with such difficulties and struggling to resolve them in ways compatible with the principles stated here. The purpose of this Code is to foster discussion and education. The American Anthropological Association (AAA) does not adjudicate claims for unethical behavior. The principles and guidelines in this Code provide the anthropologist with tools to engage in developing and maintaining an ethical framework for all anthropological work.

    The AAA Code of Ethics provides a thought provoking and informative look into some of the responsibilities Anthropologists have to their research subjects, the community of anthropologists, and the wider public.   The nature of anthropological fieldwork is particularly fraught with ethical conundrums.

    "This would be unfortunate, for the book offers a controversial account of the impact of Western research on an indigenous population that should urge us to think hard about our work. Even before its publication, Darkness in El Dorado became a Janusfaced text that in calling attention to methodological and ethical shortcomings of scientific research in the Amazon also brought attention to faults in its own production. This should not obscure its contribution or make us forget that the central issue in this drama, after all, should be the Yanomami" "At the books heart is a twostranded argument concerning the work among the Yanomami by the anthropologist Napoleon Chagnon and the geneticist James Neel. One strand follows their involvement in a complex set of medical practices centering on the collection of blood samples and a measles vaccination campaign. The other traces Chagnons spectacular career as the creator of the Yanomami as anthropologys wellknown fierce people. While Tierneys focus is on individuals, his book locates them in two relevant contexts: the cold war and the Vietnam War, during which currents of evolutionary genetics, sociobiology, and cultural anthropology claiming that aggression plays a positive role in human evolution found broad support, and the Venezuelan petrostate culture of clientelism, which fostered a network of corrupt politicians and businessmen with interests in the Yanomami and their territory for reasons of profit and power. His discussion argues that the work of Chagnon, Neel, and other scientists brought the Yanomami neither empowerment nor wellbeing but fragmentation and destruction" "The first strand of the book, which occupies less than onetenth of Tierneys text but has received the most public attention, argues that Neel and Chagnon collected blood samples for the Atomic Energy Commission to compare mutation rates in populations contaminated by radiation with those in one uncontaminated by it and at the same time carried out
