The previous article, Why Should Darwinism be Capitalistic?, invited criticism from many of my ‘evolutionist’ friends. Some were against the anti-deterministic underpinnings of the article – they were reluctant to come to terms with the ‘Nature via Nurture’ hypothesis. Others were against my suggestion that Darwinism can be supportive of Socialism rather than capitalism. What most of them complained about was my support of the job and educational reservations to weaker sections of the society.

So here are some clarifications on the issue. These are excerpts from email replies, orkut messages and internet chats. They represent my attempts to detail the:

  • the influence of environment on gene expression (nature via nurture).
  • the use of neo-darwinian evolutionary principles to fight nature’s selection forces.
  • the concept of all-round social upliftment for maximum expression of best genes.
  • the necessity of social reservation and proactive steps to uplift the backward sects of each population.

An analogy to ponder over

Imagine, two pots, with randomly allocated seeds from the same batch. The two plots have equivalent genetic potential. One plot received fertilizer (an environmental condition), the other pot receives no fertilizer. The average height (i.e. intelligence) differences between each pot will be due to environmental differences (fertilizer), however the height differences amongst individual plants within a pot are due to genetic differences (assuming similar conditions throughout the pot).
Which set of plants have a better chance of disseminating their progeny..?
Which set of plants can ensure that most of their “good” genes are transferred to the next generation ?
Progeny of which set of plants are more likely to survive with the better genes ?

Analysis

The gene for higher intellect (henceforth called “smart-gene”) definitely appears in a family/clan/race as a result of mutation and random chance, as evolutionary laws say.

Let me elaborate this:

A child named ‘Z’ in a family of traditional cobblers in India in 800 AD gets a few smart-genes. He has this constant urge to learn, enjoy philosophy or engage in intellectual pursuits. But the strict caste system and social practices of untouchability forbids him from following his heart. Even his family which doesn’t care about education is against his wishes and the boy is compelled to follow his father’s profession, marry somebody from his own caste and spend his life in the way, the strict society wanted him.

His wife, who is from a plain ordinary cobbler family, has no smart-genes. Now our “index” case of smart-gene-mutant is Mr.Z, who has very very small chance of passing his mutant smart-genes to his son or daughter. But still, let us simply suppose the genes were fortunately inherited by Mr.Z’s son. But even then, the son too has very little chance of passing that to the third generation because of the same socioeconomic set up that prevented his father from achieving his own dreams. If he defies the society, the family will soon be destroyed even before a third or fourth generation of children is born.

What if Z’s daughter is the one who inherits the smart-genes? The prospects are worse for a woman in such a rigidly hierarchical and casteist society!!

As long as the same socioeconomic conditions prevail around the family, the smart-genes find less and less chance of inheritance.

Note that there is no inheritance of acquired characters here.
The smart-genes simply rose as a result of “random aimless mutation” as Dawkins often puts it.
The only factor that environment strongly influences, is its chance of being inherited into the subsequent generation.
This situation is a kind of ‘man-made’ negative selection.
The same way we weed out poor yielding poultry or sheep from a farm.
The same way dogs, which are epitomes of servitude and fidelity, were selectively evolved from wolves

Now consider the same situation in a modern liberal Western society like the USA.

The modern Mr. Z, who inherits the smart-genes, takes a scholarship exam, pursues a college education, research in Duke, become a top rated cardiologist in North Carolina and marries the daughter of his research guide. Now his children have because his wife is likely to have the same in her gene pool too. Now, since his wife’s family has a history of intellectual members, the odds of her transmitting the smart-genes to the next generation are also higher. In whichever way you look, Mr. Z’s progeny will have greater chance of inheriting their parents’ smart-genes.

The atmosphere, in which their children grow up, will be stimulation to their genetic potentials. Better nutrition, visuo-spacial challenges of the city and top class education bring the best out of those old smart-genes.

These children, who seek out their own kind (Dawkin’s “green beard effect”) in the society, marry from families of similar or higher intellectual status. The odds of their successive generations becoming smarter improve with every generation.

Note that our Mr. Z of the21st century American city not only faces zero resistance from society but enjoys the fruits of liberty, equality and government’s financial aid in the form of grants, job reservations, scholarships, insurance etc.

This situation is beautifully condensed in the very famous FLYNN EFFECT.

Dr. James Flynn, after doing a meta-analysis of many Western IQ studies done over generations, plotted it against time, and found that average IQ scores increase with generations in the Western societies.

The reason for this is not because the earlier generations had no smart-genes. It’s just that modern western societies are more liberal & conducive for the better expression of these genes to their fullest potentials.

They permit mix up of all kinds, resulting in a global improvement of intellect rather than focal areas of brain development.

That is the most important thing about supporting reservation and other social initiatives to uplift all the sections of population rather than letting natural selection take its toll.

A short verbal ability test administered to about 12,500 adult American Blacks and whites between 1974 and 1994 support this effect of social influence. It clearly shows a narrowing of the IQ differences over recent years – a telltale sign of positive influence on gene expression.

Defying Natural Selection

It may seem strange that in highly competitive meritocratic modern societies, natural selection actually has very little toll on the individual.

If you look deeper, you will see the reason.

With the general improvement in intelligence, human societies progressively have (and will) become altruistic. It’s the selfish gene’s covert strategy to promote the survival of its own kind.

Our hospitals, medical equipments, diagnostic gadgetry, ever expanding array of drugs, humanitarian organizations, peace organizations, trade partnerships etc are towering examples of this altruism and a blatant defiance of Natural Selection.

I am not forgetting the resurgences in imperialist notions especially in recent war histories, but those can be dispensed as the old animal instinct still refusing to go off the skin.

Once the concept of “Nation” and “Nationality” wither away in the future, such notions will have no meaning at all. And by that time hominids, as a species will have something else to fight against…!

Reservation Issue

The whole meaning of reservation, scholarships and grants is to promote the maximal expression of the good genes in these oppressed castes and sects. For that, first of all, there should be some potentially smart genes that can be worked upon to be fully expressible. This means, we can’t expect the whole of those backward castes to ascend to an equal stance with the rest of the society within a very short period of time, simply from affirmative actions. Affirmative actions should essentially be followed by two things if it’s to yield rapid results: # 1) Positive change in social psyche, in accepting them and acknowledging their contributions. # 2) General increase in equality and opportunities for all.

That’s when we can claim that the society has become truly meritocratic.

 

The reservation of seats at the IITs and institutions of excellence is a complex issue. But one thing can be said. Setting apart 20 or 30% seats to the backward classes will not take away any opportunity from the general merit-class. Because, they already are evolutionarily advanced to seek and earn their share. They are already advanced intellectually. What i mean to say is that, economic independence and wealth do not solve the issue at all. The root problem is in the genes, and the remedy requires more than just a few perks to a few individuals. Mixing their genome with the general population will be the ultimate cure, but that would be too fantastic for an expectation in our society.

Spin-offs on Eugenics

I believe, we all have to learn to tolerate the current diversity of our species. We might have to accept the reality of religion-genes, criminality-genes, racism-genes, communism-genes, capitalism-genes, atheism- genes, agnosticism-genes, and what not for that matter. Within our species, each of these has a time and place – to dominate, to stagnate and even to whither away or may be even replaced by totally new genes for totally new things. But the million dollar question is whether our race is ready for that.
Most societies, be it capitalistic or communist, are growing more authoritarian by the day.
That’s a problem with all kinds of eugenics. One might argue for positive eugenics, on the basis that it promotes good qualities of human genome. But as far as our science knows it, most smart-genes are associated with some or the other kind of psychologic / organic defects in the brain – autism and schizophrenia being the ends of a spectrum. Finding a balance in the gene bridge is the biggest problem.

When smartness becomes unlimited, the person becomes a total rebel defying all laws imposed by the society.. When artistic areas of the brain are genetically pushed to its limits, the person experiences regression of the other areas which may even tend towards autism..!! (the autistic idiot savant syndrome is the best example of this kind).

If we promote negative eugenics, by not permitting” diseased” genes from reproducing, that will be an encroachment into the very nature of our life on this planet. But its a re surging concept now. Most genetic screenings are in one or the other way, negative eugenics. Its only a matter of time before the “criminals” in jails will be banned from reproducing…!!

 

Are you saying that we have to go against evolution?

Yes..!
I was exactly trying to say we have to go against evolution in this matter….!
Or else, this race won’t last another millennium…that’s for sure.

Why, because, its the unique ability of the hominids to manipulate nature to meet his needs rather than letting nature manipulate him.

Thats simply what we have been doing ever since we branched out from the primate ancestors…Just look around and we will see only those things that man has built, invented or designed, to suit his needs, to help alleviate his toil, to ease his life, to bring out the maximum of his potential…!

Our hospitals defy the very basics of natural selection by differential extinction,
Our prenatal checkups do the same
Our geriatric centers do the same
Our schools do the same
Our railway, airlines, banks, bridges and roads, our space stations, satellites, rockets, hydel power stations, nuclear reactors….you name it…Everything helps man in one way or the other in defying Nature’s forces, and saving him from being deselected..!

So why don’t we extend this privilege to all classes of people in every population..?
