Inspirational quotes with systematics.
The problem with racial discrimination, though, is not the inference of a person's race from their genetic characteristics. It is quite the opposite: it is the inference of a person's characteristics from their race. The question is not, can you, given an individual's skin color, hair texture, or language, infer something about their ancestry or origin. That is a question of biological systematics -- of lineage, taxonomy, of racial geography, of biological discrimination. Of course you can -- and genomics as vastly refined that inference. You can scan any individual genome and infer rather deep insights about a person's ancestry, or place of origin. But the vastly more controversial question is the converse: Given a racial identity -- African or Asian, say -- can you infer anything about an individual's characteristics: not just skin or hair color, but more complex features, such as intelligence, habits, personality, and aptitude? /I/ Genes can certainly tell us about race, but can race tell us anything about genes? /i/To answer this question, we need to measure how genetic variation is distributed across various racial categories. Is there more diversity _within_ races or _between_ races? Does knowing that someone is of African versus European descent, say, allow us to refine our understanding of their genetic traits, or their personal, physical, or intellectual attributes in a meaningful manner? Or is there so much variation within Africans and Europeans that _intraracial_ diversity dominates the comparison, thereby making the category "African" or "European" moot?We now know precise and quantitative answers to these questions. A number of studies have tried to quantify the level of genetic diversity of the human genome. The most recent estimates suggest that the vast proportion of genetic diversity (85 to 90 percent) occurs _within_ so-called races (i.e., within Asians or Africans) and only a minor proportion (7 percent) within racial groups (the geneticist Richard Lewontin had estimated a similar distribution as early as 1972). Some genes certainly vary sharply between racial or ethnic groups -- sickle-cell anemia is an Afro-Caribbean and Indian disease, and Tay-Sachs disease has a much higher frequency in Ashkenazi Jews -- but for the most part, the genetic diversity within any racial group dominates the diversity between racial groups -- not marginally, but by an enormous amount. The degree of interracial variability makes "race" a poor surrogate for nearly any feature: in a genetic sense, an African man from Nigria is so "different" from another man from Namibia that it makes little sense to lump them into the same category.
. . . [A] creationist spy named Luther Sunderland snuck into a closed scientific meeting of the Systematics Discussion Group at the American Museum in 1981 with a hidden tape recorder. . . . My friend, the distinguished paleoichthyologist Colin Patterson of the British Museum in London, was talking about pattern cladism and how he had abandoned many of the assumptions about evolution that he had once held, including the recognition of ancestors in the fossil record. He was now only interested in the simplest hypotheses that were easily tested, such as cladograms. But, of course, taken out of context, it sounds as though Colin doubted that evolution had taken place, yet he said nothing of the sort! Colin was speaking in a kind of "shorthand" that makes sense to the scientists who understand the subtleties of the debate, but mean something entirely different when taken out of context. I was at that meeting and was stunned to read afterward about Sunderland's account of what had happened because I remembered Colin's ideas clearly and could not imagine how they could be misinterpreted. For decades afterward, Colin had to explain over and over again what he had meant, and why he did not doubt the fact that evolution had occurred, only that he no longer accepted a lot of the other assumptions about evolution that Neo-Darwinists had made. Unfortunately, Colin died in 1998 while he was still in his scientific prime, unable to continue fighting these misinterpretations of his ideas that continue to be propagated by the creationists.
