Contributor Post Created with Sketch. Saturday Night Science: A Troublesome Inheritance

 

A Troublesome Inheritance by Nicholas WadeGeographically isolated populations of a species (unable to interbreed with others of their kind) will be subject to natural selection based upon their environment. If that environment differs from that of other members of the species, the isolated population will begin to diverge genetically, as genetic endowments which favour survival and more offspring are selected for. If the isolated population is sufficiently small, the mechanism of genetic drift may cause a specific genetic variant to become almost universal or absent in that population. If this process is repeated for a sufficiently long time, isolated populations may diverge to such a degree they can no longer interbreed, and therefore become distinct species.

None of this is controversial when discussing other species, but in some circles to suggest that these mechanisms apply to humans is the deepest heresy. This well-researched book examines the evidence, much from molecular biology which has become available only in recent years, for the diversification of the human species into distinct populations, or “races” if you like, after its emergence from its birthplace in Africa. In this book the author argues that human evolution has been “recent, copious, and regional” and presents the genetic evidence to support this view.

A few basic facts should be noted at the outset. All humans are members of a single species, and all can interbreed. Humans, as a species, have an extremely low genetic diversity compared to most other animal species: this suggests that our ancestors went through a genetic “bottleneck” where the population was reduced to a very small number, causing the variation observed in other species to be lost through genetic drift. You might expect different human populations to carry different genes, but this is not the case—all humans have essentially the same set of genes. Variation among humans is mostly a result of individuals carrying different alleles (variants) of a gene. For example, eye colour in humans is entirely inherited: a baby’s eye colour is determined completely by the alleles of various genes inherited from the mother and father. You might think that variation among human populations is then a question of their carrying different alleles of genes, but that too is an oversimplification. Human genetic variation is, in most cases, a matter of the frequency of alleles among the population.

This means that almost any generalisation about the characteristics of individual members of human populations with different evolutionary histories is ungrounded in fact. The variation among individuals within populations is generally much greater than that of populations as a whole. Discrimination based upon an individual’s genetic heritage is not just abhorrent morally but scientifically unjustified.

Based upon these now well-established facts, some have argued that “race does not exist” or is a “social construct”. While this view may be motivated by a well-intentioned desire to eliminate discrimination, it is increasingly at variance with genetic evidence documenting the history of human populations.

Around 200,000 years ago, modern humans emerged in Africa. They spent more than three quarters of their history in that continent, spreading to different niches within it and developing a genetic diversity which today is greater than that of all humans in the rest of the world. Around 50,000 years before the present, by the genetic evidence, a small band of hunter-gatherers left Africa for the lands to the north. Then, some 30,000 years ago the descendants of these bands who migrated to the east and west largely ceased to interbreed and separated into what we now call the Caucasian and East Asian populations. These have remained the main three groups within the human species. Subsequent migrations and isolations have created other populations such as Australian and American aborigines, but their differentiation from the three main races is less distinct. Subsequent migrations, conquest, and intermarriage have blurred the distinctions between these groups, but the fact is that almost any child, shown a picture of a person of European, African, or East Asian ancestry can almost always effortlessly and correctly identify their area of origin. University professors, not so much: it takes an intellectual to deny the evidence of one’s own eyes.

As these largely separated populations adapted to their new homes, selection operated upon their genomes. In the ancestral human population children lost the ability to digest lactose, the sugar in milk, after being weaned from their mothers’ milk. But in populations which domesticated cattle and developed dairy farming, parents who passed on an allele which would allow their children to drink cow’s milk their entire life would have more surviving offspring and, in a remarkably short time on the evolutionary scale, lifetime lactose tolerance became the norm in these areas. Among populations which never raised cattle or used them only for meat, lifetime lactose tolerance remains rare today.

Humans in Africa originally lived close to the equator and had dark skin to protect them from the ultraviolet radiation of the Sun. As human bands occupied northern latitudes in Europe and Asia, dark skin would prevent them from being able to synthesise sufficient Vitamin D from the wan, oblique sunlight of northern winters. These populations were under selection pressure for alleles of genes which gave them lighter skin, but interestingly Europeans and East Asians developed completely different genetic means to lighten their skin. The selection pressure was the same, but evolution blundered into two distinct pathways to meet the need.

Can genetic heritage affect behaviour? There’s evidence it can. Humans carry a gene called MAO-A, which breaks down neurotransmitters that affect the transmission of signals within the brain. Experiments in animals have provided evidence that under-production of MAO-A increases aggression and humans with lower levels of MAO-A are found to be more likely to commit violent crime. MAO-A production is regulated by a short sequence of DNA adjacent to the gene: humans may have anywhere from two to five copies of the promoter; the more you have, the more the MAO-A, and hence the mellower you’re likely to be. Well, actually, people with three to five copies are indistinguishable, but those with only two (2R) show higher rates of delinquency. Among men of African ancestry, 5.5% carry the 2R variant, while 0.1% of Caucasian males and 0.00067% of East Asian men do. Make of this what you will.

The author argues that just as the introduction of dairy farming tilted the evolutionary landscape in favour of those bearing the allele which allowed them to digest milk into adulthood, the transition of tribal societies to cities, states, and empires in Asia and Europe exerted a selection pressure upon the population which favoured behavioural traits suited to living in such societies. While a tribal society might benefit from producing a substantial population of aggressive warriors, an empire has little need of them: its armies are composed of soldiers, courageous to be sure, who follow orders rather than charging independently into battle. In such a society, the genetic traits which are advantageous in a hunter-gatherer or tribal society will be selected out, as those carrying them will, if not expelled or put to death for misbehaviour, be unable to raise as large a family in these settled societies.

Perhaps, what has been happening over the last five millennia or so is a domestication of the human species. Precisely as humans have bred animals to live with them in close proximity, human societies have selected for humans who are adapted to prosper within them. Those who conform to the social hierarchy, work hard, come up with new ideas but don’t disrupt the social structure will have more children and, over time, whatever genetic predispositions there may be for these characteristics (which we don’t know today) will become increasingly common in the population. It is intriguing that as humans settled into fixed communities, their skeletons became less robust. This same process of gracilisation is seen in domesticated animals compared to their wild congeners. Certainly there have been as many human generations since the emergence of these complex societies as have sufficed to produce major adaptation in animal species under selective breeding.

Far more speculative and controversial is whether this selection process has been influenced by the nature of the cultures and societies which create the selection pressure. East Asian societies tend to be hierarchical, obedient to authority, and organised on a large scale. European societies, by contrast, are fractious, fissiparous, and prone to bottom-up insurgencies. Is this in part the result of genetic predispositions which have been selected for over millennnia in societies which work that way?

It is assumed by many right-thinking people that all that is needed to bring liberty and prosperity to those regions of the world which haven’t yet benefited from them is to create the proper institutions, educate the people, and bootstrap the infrastructure, then stand back and watch them take off. Well, maybe—but the history of colonialism, the mission civilisatrice, and various democracy projects and attempts at nation building over the last two centuries may suggest it isn’t that simple. The population of the colonial, conquering, or development-aid-giving power has the benefit of millennia of domestication and adaptation to living in a settled society with division of labour. Its adaptations for tribalism have been largely bred out. Not so in many cases for the people they’re there to “help”. Withdraw the colonial administration or occupation troops and before long tribalism will re-assert itself because that’s the society for which the people are adapted.

Suggesting things like this is anathema in academia or political discourse. But look at the plain evidence of post-colonial Africa and more recent attempts of nation-building, and couple that with the emerging genetic evidence of variation in human populations and connections to behaviour and you may find yourself thinking forbidden thoughts. This book is an excellent starting point to explore these difficult issues, with numerous citations of recent scientific publications.

    Fred Cole: There’s a few things wrong with your statement. First, the name England comes from the Angles who settled there in the early Middle Ages, after coming over from Germany. Second, the Huns probably came from northern China. They warred and pillaged all the way to Europe. If you don’t think they interbred, they most certainly did. When they got to Europe, they most certainly interbred. There was a constant mixing of people in “ancient times.” So it’s entirely possible that Angles in Germany mixed with Huns from northern China, and their descendants carried those genes to England. Pre-Angle Romano-Britain was a mix of local tribes and Romans. There wasn’t one Roman ethnicity. Romans came from all over the empire, including north Africa and Egypt (in Africa) and the eastern provinces (in Asia). And there were trade contact up and down the silk road, intermixing people of different populations even then. And that’s just “ancient times.” The Middle Ages were full of invasions and migrations and movement of people, including the Golden Horde. And when they came through, they pillaged and raped.

    I would disagree.

    Nomadic short-lived invasions had relatively little impact on the settled populations in terms of inter-marriage (or breeding).

    In the past it took very long periods of time for inter-marriages to occur between populations even living in extreme proximity to each other (of course, if you think race doesn’t exist, try imagining what it meant in 200AD for people in a small village to have people with a different language, religion, and culture live next door. NO WAY were they inter-mingling)

    Now we know this mainly because of the toponyms of villages throughout Europe, and subsequent observations of how people in regions with inter-mingled ethnicities lived alongside each other into modern times (into the 20th century).

    You could have a village with a Bulgarian name next to one with a Greek or Aromanian or Albanian name…with the populations neatly divided ethnically in their respective village. This even into the 20th century.

    They did not inter-marry, either genetically or culturally. 

    These sort of mixing happened only after centuries of co-existence in permanent settlements.

    Nomadic populations never had such an impact on settled populations. They led to de-population of certain areas because they engaged in slavery and plundering, but they did not replenish the population with permanent settles of their own. Their conquests were short lived. This was the case with the Huns, the Bulgars and any other barbaric nomadic population you can think of.

    Second, the “Huns” weren’t “Chinese”. Evidence from their language indicates they were some sort of proto-Slavic/ Scythian/Iranian/Turkic mix…which were the dominant ethnic types in the region you described (not the Chinese and pre-Mongolian).

    We know the Slavs are a mixture of these groups (Scythian-Iranian types), as are Hungarians and Bulgars.

    So….no. No Han Chinese mixing in England :) Sorry.

    As for the Romans, yes of course they were a mixture of ethnicities. But all these ethnicities were…white. Could there have been a couple of guys from North Africa (who were actually of Berber descent…most of the Roman settlements in North Africa were actually settled by…Romans) who went to England and married there and had kids? Yes of course. But in population terms, that’s insignificant.

    Now, if you think “race” is a modern social construct and doesn’t actually exist, or didn’t exist in the past, or doesn’t exist in other cultures…then you really need to read up on how people even in the relatively recent past lived in ethnically diverse regions of Europe.

    Forget race. These people sub-divided themselves by language, religion and culture. And they segregated themselves into different villages on those bases. They did not inter-mingle.

    Marriages across these villages were rare and coordinated efforts. I.e., someone in the village would have had to have run out of marriage material that wasn’t related to him/her by blood…and in the cluster of related villages of the same ethnicity/religion/clan…for them to go to a village of unrelated ethnicity.

    I.e., it was an option of last resort.

    It happened, but it was an extremely slow process. And it could only happen if both populations were settled in the same area, for prolonged periods of time.

    Which is why, in reality, you get virtually no mixing across continents or races. You first have to overcome the barrier of language, religion, culture…and then geography…and then time…to arrive at the point of inter-marriage.

    But the point being that people, across the world, were and are extremely…aware…of even minor differences between populations. And it takes an enormous amount of historical circumstances to overcome such…awareness. Never-mind something as obvious as race.

    What we in America call being a “bigot” or a “racist”, for the vast majority of the people in the world, for the vast majority of human history…was/is called being “normal”.

    I read recently that 18% of the four year olds in federally funded pre-school programs are black, yet they make up 48% of the students expelled from those programs. Disparate impact analysis would suggest we have an epidemic of closet Bull Conners going into the pre-school teaching profession. The alternative is that possibly traits such as the MAO-A gene mentioned above, compounded by the intense social pathologies of life in the underclass, has some impact on impulse control, emotional stability and the complex of behaviors needed to live in our civilization rather than a hunter-gatherer one.

    Why should it be taboo to address these issues, and why can’t social policy be modified after it bumps it’s fuzzy head on reality? We should start by requiring Norplant or some similar effective birth control for anyone who is so disorganized they become a public ward. Conversely we should organize tax and subsidy policies to promote fertility by those who have the foresight to grasp the costs and obligations of childbearing. I do not think these ideas are eugenics in the common pejorative sense of the term, and I think they would have a lot of public support.

    If you have ever witnessed (as I have) otherwise responsible middle-class people altering their behavior in pernicious ways in order to qualify for more government goodies, I wonder whether you’d be so quick to say that.

    Offer a subsidy even for “good” behavior, and you shift people’s motivations from caring for themselves and their family as best they can with the resources they have to getting as much out of the public fisc as possible at their fellow taxpayers’ expense.

    Responsible people – especially the aggrieved middle class – aren’t above wanting to “get their own back”, even if doing so undermines the very habits that make them responsible.

    While I don’t necessarily agree with the overall point of your comments, I do agree with this point.

    But as Rattlesnake said, this goes against the current policies which try to incentivize births through financial incentives.

    It also goes fundamentally in the opposite direction to the recommendations of the “social conservatives” and the “value-conservatives” and the conservative policy wonks that we have seen here in Ricochet in large numbers.

    Their arguments are that we should incentive births because more children leads to greater economic prosperity…yada yada yada. Rachel Lu can make the points better than I can ;)

    But…the people who are incentive by financial rewards on child bearing are precisely the poor. The middle and upper income people aren’t incentiveized by such. They’re not having kids because they don’t have the time, not because they can’t afford them.

    Hence…the best incentive programs to dis-incentivize “poor” people from having kids, which will then flood the government welfare system…is to stop providing financial incentives for having kids.

    Have the parents bear the full costs. That will send the message that those who should be having kids are those who will be able to afford them, and not impose them on the rest of society.

    John Walker:

    Randy Webster: How is going through a bottleneck different from just starting from a very small number?

    There is no difference in principle. It’s just that whenever you have a small initial population which subsequently grows to a much larger one, the genetic diversity in the resulting population will be smaller simply because the original population couldn’t carry many different versions of genes purely due to its limited size.

    When a large initial population is reduced to a small one and then subsequently recovers, this is referred to as a population bottleneck, while when a population starts from a small number of settlers who are then cut off from interbreeding with their source population (for example, a small group who have migrated to an isolated island), it is called the founder effect. The result is the same.

    It is believed that the human population went through a population bottleneck which resulted in its high level of genetic uniformity because there isn’t evidence for an event in human history in Africa which could invoke the founder effect. One suggestion for the origin of the bottleneck is the Toba catastrophe theory, in which the eruption of a super-volcano in Indonesia around 70,000 years before the present produced a rapid and severe climate change which may have reduced the human population in Africa to around 10,000 individuals. This was around 20,000 years before humans migrated out of Africa, so the effects of this bottleneck would affect the entire global population, which is what is observed.

    The founder effect is evident in that the genetic diversity of humans in Africa is much greater than those in the entire rest of the world. This can be explained if the migration from Africa to the north was by a small group of humans. That small founder population would necessarily be less diverse than Africans as a whole, and their descendants would carry only the limited genetic heritage they brought with them.

    The very low genetic diversity of the human species is well-documented. Theories of its cause are speculative and based upon only sketchy evidence at present.

    Doesn’t this make the term “African American” a bit silly given that Africa is so genetically diverse. Is it perhaps why real Africans mostly identify with their region or country rather than the continent of Africa.

    John Walker: But it seems like there is a strained dogmatism among some cultural anthropologists in arguing that genetics never has an influence.

    This shows itself in the Leftist habit of insisting that unless one can point to a purely biological mandate for a particular cultural trait, that trait can be abolished at will and replaced with something more congenial to their ideology. Unless someone can prove that there is a biological basis for, say, property rights, we should be able to sweep them aside and choose to live in a Socialist paradise instead.

    The flaw in this logic is that culture is an evolutionary process which discovers truths about what works in the real world, in a manner analogous to biological evolution. Even if there is no genetic basis for property rights, or gender roles, or social hierarchy, or the cannibalism taboo, there is an evolutionary basis for them that confounds efforts to discard them.

    Paul DeRocco: That isn’t to deny evolution, merely to ascribe greater strength to that cultural form of evolution that seems invisible to most people than to the biological form that everyone is taught about in school.

    The interplay between cultural evolution and genetic evolution is a complicated and interesting topic. When I took my students to the zoo, the topic of elephant social behavior came up. Elephant herds consist of female adults and juveniles. The adult males live on their own, or sometimes in “bachelor herds,” and only come to the main herd to mate. My students recognized this “Oh, they’re baby daddies!” I said, “Basically, yes.”

    I wonder if a cultural practice like “baby daddying,” if it goes on long enough, could lead to genetic evolution that reinforces the cultural trait. It would be not unlike the way cultures that practice dairy farming tend to acquire lactose tolerance. It’s a fascinating and troubling idea.

    That’s true. Genetically speaking, the “African race” is really multiple races. Africa is the trunk of the human family tree, and Europeans, Asians, etc. are thin branches growing off of that trunk.

    Randy Webster: I call bullsh**t, Fred. No one’s used the “one drop” rule since the 50′s. Obama is black because he says he’s black. Pure and simple. It got him bennies when he needed them. Who are we to gainsay him?

    I don’t think it’s b.s., because Fred is actually describing a different “one drop” rule from the one under which a few individuals who appeared white could be held in slavery, or otherwise discriminated against. The Left’s new “one drop” rule is what allowed Harvard to congratulate itself for its “diversity” because of the presence of Elizabeth “Fauxcahontas” Warren on the faculty. It’s what makes Barack Obama, 50% white and raised almost entirely by his white mother and grandparents, prefer to be called “black”. But it’s still a “one drop” rule.

    This is certainly odious, but in a different way from the old rule. Although the old rule was ignorant, it wasn’t incompatible with a confident culture that was capable of thriving in the world. When the dominant culture decides to regard its own patrimony, whether racial, political, philosophical, or economic, as something to be ridiculed or denigrated, the result isn’t likely to be sustainable for very long.

If a deer came in contact with it ,the deer died. They learned to avoid it.After unification the fence was taken down.Several generations later the descendents of the deer were still avoiding the area were the fence once was. They did this even though they had no actual remembrance of the fence. The fear was some how passed from generation to generation . Is this different than human behavior ?

    Fred Cole: Race is indeed a social construct. And it’s a social construct that varies from place to place and over time.

    I don’t think race is a social contruct, but racial divisions are fuzzy. I think “race” is just ‘family” on a larger scale. You can often tell people share the same parents or grandparents based on observable similarties (i.e. relateness). Likewise, you can often tell that people share ancestors based on observable similarities (race). E.g. two people of East Asian ancestry probably share more ancestors than they do with someone of European ancestry. Family boundaries and racial boundaries are fuzzy and shifting, due to intermarriage/interbreeding between families, which families naturally do. Family and racial boundaries can be made more sharp if interbreeding is suppressed, but by nature these boundaries are made to be crossed.

    Son of Spengler:

    Mendel: In this vein, there is a similar concept I think we should consider: when there is indeed a difference in a trait between two groups, but there is even greater variation in that trait within each group.

    Yes! This so important, and so rarely understood. If I randomly select Man A and Woman B and they run a mile, without any more information I can’t say with any confidence who will have the faster time. But if I do the same with 10,000 men and 10,000 women (randomly selected), I can say with some confidence that the men’s average will be shorter, and that the top times will be dominated by men. So one can’t prejudge any individual’s ability or outcomes, even if we know what group he or she is a part of — the individual variation is too great. That’s true even when the group is overrepresented among marathon winners or Nobel Prize winners or violent felons.

    This is important enough to bear repeating.

    Culture is not limited to humans. Some animal behaviors are instinctive, but other behaviors are learned, either from parents or other members of the species. Animal culture consists of things like a squirrel watching another squirrel eating a tomato, then doing likewise.

    You were quite correct to provide a warning before citing Noam Chomsky. Fortunately you were referring to his work as a linguist and not those other fields in which he has made a name for himself (as an intellectual to the usual crowd, and as a bona-fide kook to the rest of us).

    And the work you cited was sort of an interesting distraction. Right there at the top of page 14 I found a statement that seems to me to sum up an awful lot of the problem with Big Evolution:

    Mendel:But that doesn’t mean that using these categories isn’t useful, provided we understand their limitations. So could it be with race, for instance with health and genetic predispositions – even if it may be off the mark with some people.

    Exactly. The trick in such thing is always to remember that our categories are meant to serve our understanding of reality; reality itself may not always play ball, and is usually more complicated.

    “…I can’t imagine how it could be any other way.”

    I think he shows a serious lack of imagination.

    Indeed he does, in that sentence, but that’s not really a fair criticism of him overall (lack of imagination) and nor is it the point. Fact that he can’t quite bring himself to say, “If A, then B, A, therefore B,” hardly means we’re forbidden from pointing it out, does it?

    Mendel: In this vein, there is a similar concept I think we should consider: when there is indeed a difference in a trait between two groups, but there is even greater variation in that trait within each group.

    Yes! This so important, and so rarely understood. If I randomly select Man A and Woman B and they run a mile, without any more information I can’t say with any confidence who will have the faster time. But if I do the same with 10,000 men and 10,000 women (randomly selected), I can say with some confidence that the men’s average will be shorter, and that the top times will be dominated by men. So one can’t prejudge any individual’s ability or outcomes, even if we know what group he or she is a part of — the individual variation is too great. That’s true even when the group is overrepresented among marathon winners or Nobel Prize winners or violent felons.

    This is important enough to bear repeating.

    This is true and important when making certain (but not all) decisions about individuals. However, when making public policy decisions about groups it makes sense to take group characteristics into account. This is why the concept of disparate impact is so pernicious. It leads to perverse outcomes such as race-norming the results of perfectly fair tests when those results don’t reflect a false group equality.

    Group characteristics also are important to those aspects of decision-making about individuals in which actuarial calculations come into play. Race, sex, and age are just a few of the data to be taken into account when setting insurance premiums or pension contributions, if we want to avoid some persons subsidizing others who have differing actuarially computed expected payouts.

    Finally, there are times when decisions must be made based on probabilities, because that is the only information available. For better or worse, race is one of the characteristics that affects probabilities; everyone knows this and, what is more, they act as if they know it.

    Claire Berlinski: I threw a nuclear bomb into what had up to that point been a mere flamethrower-level discussion. I am quite sad that no one really noticed.

    When I clicked the link Google Books told me the pages were not available for preview. Maybe this happened to other people too.

    Odd, that. What might cause it to be easily visible to me but not you? What’s the solution? (I could find another reference, of course–we are spoiled for choice where “Chomsky’s verbal output” is concerned, as well as his “output on all things verbal,” for that matter, but I’m curious about why I can see it but you can’t.)

    You can use the reason I always fall back on in situations like this: his computer doesn’t like him very much.

    The same thing happened to me. Just take the quote from the article and/or the search item from the google book page and reopen google books afresh, not via the link and then search search google books for the quote (you can cut and paste it) and the pages will come up.

    Told me that too many people had previewed it lately and to try again later.

    Fred Cole: Current conditions in Africa, or Europe, or China, or anywhere else, are the product of history. It’s far easier to explain the mess in various countries in Africa by history than trying to explain it with genetics.

    The more relevant question is whether history itself may be shaped by genetics. If different local geographic conditions led to evolution of subtlely different forms of social organization, we should not ignore the implications of genetics on, e.g., the emergence of different forms of government. Being too trusting of strangers can be more deadly in more sparsely populated regions, whereas a lack of trust can be a disadvantage in more dense human settlements. If a propensity to trust strangers has a genetic basis, then that cannot be ignored when wondering why e.g. Bedouin, Han Chinese, and Scandinavians developed different types of governmental systems — and why those differences may persist even after the advent of modern telecommunications. We study social organization in ants, bees, and bonobos with an understanding that genetics plays a role. Why not also for human mammals?

    John Walker: But in populations which domesticated cattle and developed dairy farming, parents who passed on an allele which would allow their children to drink cow’s milk their entire life would have more surviving offspring and, in a remarkably short time on the evolutionary scale, lifetime lactose tolerance became the norm in these areas. Among populations which never raised cattle or used them only for meat, lifetime lactose tolerance remains rare today.

    This is a great story, but in fact “lactose tolerance” appears to have little to do with lifetime consumption of dairy. Populations that are most reknowned for their dairy consumption may have low incidence of this gene, and some populations with the highest incidence do not consume dairy.

    I don’t know why this gene has spread so quickly, but it’s not required for healthy consumption of dairy—that much is perfectly clear.
