Many of the so-called 'developments' of Europe were actually imported from Africa and the near, middle and far east. That includes most of the technologies that made it possible for the Europeans to get so bloody good at warfare and so bloody rapacious with regard to material wealth. Have you studied much of Ethiopia, it's had a very high state of development for over 2000 years. It's problem was mostly it's isolation because of religious issues and the relative undevelopment of neighboring lands and peoples. Development is often and usually a matter of competition and cooperation with neighboring lands and peoples. If the Europeans are so developed, what were they doing during the time before and through much of the Roman Empire? Indeed, most of the conquering 'barbarians' that overran Rome, at least western Rome, were peoples moving in from the East. And, how do you define 'race'. Is it just an area? A given territory? Or certain ethnic groups? Or do you have specific physical characteristics you use? Were the Irish a stupid and base race? The English were convinced of it for centuries. How about the Italians, or the Spanish or the Eastern Europeans? Are the various peoples of India 'backwards'? They would have laughed at the stupidity and backwardsness of most all Europeans a 1000 years ago. For that matter, what race are you? And how do you know?

Overall, considering the studies of human genetics with respect to whether "races" exist or not, I tentatively conclude that they do not. That's considerably firmer than I was before I looked into it, and it's been a few years and given I haven't heard any of this horseshit lately, my pretty good guess is that if I were to look now I'd find a few new studies that confirm it more strongly.
So the question becomes much easier: should scientists study something that apparently doesn't exist's effects? No, not really. Not much point in it. Prove race exists first, then we'll start talking about what characteristics races have. |

Random mutation is one source of variance but there are others. Natural selection is, as you say, the term used for the process by which genes that tend to reduce an organism's chance of replication become less prevalent in the population over time. Thus, over time, the genome of the population contains information as to how to build an organism that is fitted to its environment. That information comes from the environment. (maybe this little derail needs to go into E&O?) |

You should mention them. An important one is recombination; that happens in sexual reproduction. Another that's a lot less important in species that reproduce sexually, but a lot more important among microorganisms that don't, is genetic transfer, which can occur in a number of ways including by viruses, preons, and as a result of feeding (yes, really).
There is an impression that new genes arise only by mutation. That impression is incorrect, and in fact is only a small part of the likely genetic changes over time within a species, particularly one that reproduces sexually. |

And we know that there are physical characteristics, reflecting ancestry, that increase the probability that certain alleles will be present in an individual from an individual from one "racial" group, relative to an individual from another. But all that tells us is that social "race" groupings reflect social attitudes to ancestry especially where ancestry is visible in the form of superficial physical attributes. Where an individual's ancestry does not make them part of a visible social "race" grouping, we have no way of correlating their ancestry with their genotype. For all I know, Brits with a genotype that represents Danish ancestry may be less potentially intelligent than Brits with a genotype that reflects Celtic ancestry. But we can't know because we don't socially construct Brits into Danes and Celts. And we have absolutely no way of knowing whether depressed mean IQ scores in a US racial grouping that is highly correlated with environmental disadvantage has anything to do with allele distributions in that group because we also know that IQ scores are highly correlated with non-hereditary factors, including environmental disadvantage, and we also know that distribution of most human alleles in the human population is pretty uniform. So a good first place to look for causal factors would in the environmental domain. And if we are interested in the relationships between genes and IQ, we'd go should go for a far better proxy than race. |

From an evolutionary standpoint I follow Cavalli Sforza in arguing it's better scientifically to think in terms of lineages than races. There are definitely multiple streams of humanity that diverged at various points along our evolutionary history but that can all be traced back to a common source - modern Homo sapiens in Africa. "Race" is how each of those streams appears temporarily if you treat it as a fixed point (and then draw all sorts of sociocultural conclusions from that) but in reality the streams are all connected and often merge and mix their waters before diverging again in new configurations. Race as a concept seems to be trying to fix something that is by it's nature in a state of flux. Throughout our history as a species there have been many points where whole lineages have become relatively isolated from each other and that has, through evolution, led to diversity. However when those groups have come into contact with other lineages, as we are still one species (and therefore one gene pool) the overall tendency has been for lineages to merge in various ways: through outgroup marriage, through mutual accommodation, assimilation and integration. through conquest and even enslavement. There have also always been opposite tendencies - groups of people who wished to keep their lineage "pure" for various social, political or religious reasons but reality has tended to undermine these attempts and on a grand historical scale they are limited.
The reality is the human race is in a continuous process of flux and change over time - genes that confer benefits may start out in certain lineages (how could it be otherwise?) but have the ability to spread throughout the human gene pool which is only limited by temporary separations and these days perhaps even less so.

Genetic variation within any traditionally or socially defined "race" actually exceeds variation between the races. In other words, people of the same race are more likely to be genetically different, and are likely to be more different, than the races are from one another, genetically. Race is completely, entirely, and totally a social construct. It has no basis in genetic reality. That must be said, over and over again, until it is understood and we hear no more of this. I'm happy, parenthetically, to find that I was correct. Additional evidence has been found. Quote:
I say again, show it has some real meaning before you use it. I don't argue with the rest, but you need to know this- you need to accept it, and pass it on. This is the truth: race is a lie. There is no race. It doesn't exist. And that fact is scientifically proven, in a multi-tens-of-millions-of-dollars genetic fact-finding project that is one of the more well-known such projects in genetics in the world. When we accept this, believe it, and pass it on, this bullshit will stop. Until it stops, I will keep passing it on. ETA: My bad, my google-fu was good but my link-posting-fu let me down. Try this and this, for news sources, and Wikipedia has an excellently sourced article that goes into enormous detail. The current recommendation from the Human Genome Center at Howard University is that race is not genetically determinable; given a DNA sample, the "race" of the contributor could not be determined with certainty.

My personal take is that there are some genetic differences, but that culture is a major amplifier of those differences. And those differences may account for the likelihood of developing technology at a higher rate, but in the long run they don't really stand in the way of adopting technology, and can even be completely overcome.

Race exists both as a social construct and a physical reality. But, as Febble says, that doesn't always make it a good proxy for other heritable traits. |

I don't suppose since it's highly unlikely that any evidence regarding innate intelligence capability is likely to be found that I have much problem with looking into it, but there are three problems that will have to be addressed: 1. There are people with an agenda in this, and as we all know well, people with an agenda don't tend to get very accurate results. I won't say "lie," though that happens too; at best, it's a matter of cherry-picking. 2. In many countries, there are profound economic differences based on perceived racial characteristics. These can have a strong impact upon results unless controlled for. 3. The techniques for testing intelligence have been shown to be culturally relative, and thus don't really test for intelligence, but for adaptation to the dominant culture. So better tests that don't count on culturally relative cognitive constructs are required, and do not exist. Given all of these things, I see it as primarily a waste of time, and secondarily a source of propaganda of unpleasant character. If anyone can see a way to avoid these deficiencies, by all means have at it, but I will remain highly skeptical of the results. |

The Percent Scams Knowledge from the genome project has already helped put in perspective some previously misunderstood, or intentionally misrepresented, genetic information — what I call the “percent scams.” There have been two main scams, one at one percent, another at six percent. The one percent scam started from genuine surprise among scientists at the similarity in base sequences between early samples of chimp and human DNA. In some comparisons it appeared that we shared about 99 percent of our genetic material with the chimpanzee, and egalitarian anthropologists immediately exploited this similarity. If there is only one percent of difference between the two species, it must follow that all men are genetically functionally equivalent. By this “proof,” racial differences must be due to historical accident and cultural differentiation — not genetic differentiation — since there is no room for genetic differentiation. Better understanding of the genome reveals that “percent difference,” is not a relevant comparison. Small differences can matter tremendously. Mice and humans, for example, have many DNA sequences in common, and many mouse genes are very similar to human genes. It takes a lot of the same genetic blueprint to build mammalian bodies with liver, spleen, digestive tract, skeletal systems, and nervous systems. And, in fact, there are many similarities between mouse and man, as any anatomy student can verify by direct examination. There are also important differences. With apes we share many of our genes. However, we could share 99 percent of our base pair sequences and still differ in 100 percent of our gene products, depending on how the one percent difference were distributed throughout the genome. Since genes and protein products interact in complex ways, often small differences in genes can cascade to enormous differences in final traits. As an example, consider that among humans the manifold differences between the sexes are, on present evidence, the result of a difference in only one gene. The gene in question is a regulatory gene, that is, its primary product interacts with the DNA to regulate the expression of many other genes. With the tdf gene (testes determining factor, also known as Sry, or the Sex determining Region of the y chromosome) you get a male; without the tdf gene, a female. Sry is only one gene out of 50,000 to 100,000. The argument that the “only one percent difference” between ape and man is evidence for genetic identity among humans can now only be maintained as a deliberate scam. The six percent scam began in 1972 with Richard Lewontin. He is the brilliant Harvard biologist who co-authored (with Leon Kamin and Steven Rose) the Marxist screed Not in Our Genes, and coined the term “jensenism” to denigrate and demonize both an outstanding scientist and an entire area of investigation. In the early days of population comparisons of allelic patterns, Lewontin catalogued the frequencies across seven racial groups for 29 alleles from 17 gene loci, from which he calculated a statistical genetic diversity index. He reported that 85.4 percent of the genetic diversity was contained within local populations, an additional 8.3 percent of the diversity was between populations within a race, and only 6.3 percent of the genetic diversity differentiated the major races. (These are percentages of Lewontin’s index, and not percentages of genes, so the numbers are not comparable to the percentage of genes shared by humans and chimps.) Other investigators have reported similar results. From the finding that only about six percent of the diversity differentiated the major races, Lewontin ended his 1972 paper with the politically correct non sequitur that: Quote:
It has indeed been a surprise to many geneticists to discover how much genetic diversity there is in local populations. Two brothers, for example, share fully half their alleles by descent, but differ in countless ways. According to Lewontin’s statistical formulation they account for much genetic diversity just between the two of them. Nevertheless, to understand how meaningless this approach is as an analysis of racial differences, one might consider the extent to which humans and macaque monkeys share genes and alleles. If the total genetic diversity of humans plus macaques is given an index of 100 percent, more than half of that diversity will be found in a troop of macaques or in the population of Belfast. This does not mean Irishmen differ more from their neighbors than they do from macaques — which is what the Lewontin approach slyly implies. Pattern Diversity Since the mid-1980s there have been a number of population surveys looking at genetic diversity, and virtually all the serious ones find the same racial patterning. The thousand-page tome published in 1994 by L. Luca Cavalli-Sforza and his colleagues ( The History and Geography of Human Genes) is one of the better known. They present 491 world populations using data for 128 alleles at 45 polymorphic loci. The populations are grouped in various meaningful ways, aggregated into 42 populations, which are combined into nine clusters. Cavalli-Sforza et.al. are adamant that they are not studying races, but rather populations of humans. However, their nine clusters have a familiar ring: “Africans (sub-Saharan), Caucasoids (European) … Northern Mongoloids (excluding Arctic populations) …” (1994, p.79) The figure on this page presents a graphic schematization of their major findings with regard to patterning of genetic diversity. In their words, from their genetic data, “the greatest difference within the human species is between Africans and non-Africans … The cluster formed by Caucasoids, northern Mongoloids, and Amerinds is reasonably compact in all analyses.” (1994, p. 83) -- G. Whitney; "Race, Genetics & Society" |
