They say that naturally those people who are descended from black Africans will have a certain set of features in common. We recognize that and refer to them as "blacks," which is meant to be a neutral, more respectful form, I guess. And those genes for the broadened nose, thick lips and fuzzy hair are naturally passed on from one generation to the next. What the article is saying is that the historical background of a population -- and he gives examples of bizarre places I'd never heard, like a group in NW Pakistan, who are of Indo-European descent (linguistically and ethnically). But all in all the genome does not indicate we have a biologically ueful definition of race. If there's more genetic diversity within, say, a south Asian population, than they share with other groups. I know it's not really fair just to post an abstract, because it means I'm giving you the hay with which to build a straw man. But it's my fault for handing you the straw (no joke or sarcasm meant). It may put Tom Murphy in an embarrassing situation, and as some of you know, FAIR recently put out an article which is linked to in this month's FAIR newsletter. We've been working hard at finding a conspiracy (yeah, yeah, I know. "It's Ironic" as Alannis Morisette might sing), and now that we have smoking guns from the bugs under the rocks (now there's a mixed metaphor!). The next step is to address the claims made in his article. Some of this has already done by Scott Woodward of BYU, who delivered a presentation on the DNA work BYU's doing). making things just a bit hotter in the "Morque" (www.exmormons.com). I believe Ben McGuire already has an article up on FAIR's website about DNA research. In my opinion, unless I'm missing something (genetics is something I know very little about other than what I've read in Scientific American, say), this pape (from Science) might put a big kaibosh on anyone thinking they can prove or disprove that modern day First Nations descended solely from the Book of Mormon, which is what Tom Murphy, who admittedly went inactive in 1993, claims in his review for "American Apocrypha" among other venues. > > > General agreement of genetic and predefined populations > > suggests that self-reported ancestry can facilitate > > assessments of epidemiological risks > > Wow.

What the full paper shows is that that strictly in terms of the DNA samples, you cannot "prove" that one person's black and the other's Asian, and see that reflected in their DNA. There's a lot of genetic diversity in Africa -- in fact, more than the rest of the world combined. But because there is a weak correlation indirectly through the genes that expressed the proces that led to a "racial" characteristic. But because we self-identify our race one way or another when seeing a doctor, we should know that various races have varying diseases and this will guide the doctor's diagnosis. For or example, if your black and you feel anemic and run-down, then the doctor needs to check for sickle cell anaemia, because the gene for that is found widely throughout Africa. While this mutation gives a significant portion of the population sickle-cell anaemia, whereas if a Caucasian came in, the doctor should simply do a red blood cell count (a simple test at a medical lab). Incidentally, this very racial anomaly, the tendency to get a disease that is not nearly as common amongst people from other areas from, also provides natural protection against malaria, which still rampant in most of Africa. So it can go from, say IF [RACE = BLACK THEN GOSUB [CHECK FOR MALARIA], But the converse doesn't hold -- IF [BLOOD TEST FOR SICKLE CELL AMAENIA] = YES. One can't go from the race alone, even if it's sometimes a useful indicator if the patient tells the doctor he originally came from West Africa several centuries ago. Another example is benign prostate infection, which is more common amongst black males than amongst white males, age-adjusted [at least in the US blacks will get his out of proportion to their population. The condition is usually caused by Benign Hyperplastic Prostate (BHP, and just like the sisters need to do regular breast exams, and occasional pap smears, men 35 years on up should have an exam (which isn't particularly comfortable) for prostate enlargement. -- Marc A.
