Mommy, what were Pandemics like?

Curiously enough, in 2006 the made-up word TamiFlu became part of the household lexicon of the average news-consuming adult. The drug has proved the equivalent of Microsoft's seminal Disk Operating System for its maker (but not inventor), Roche, which could not produce it quickly enough to keep up with massive demand, driven largely by wealthy clients such as the national governments of France and the US, which are developing stockpiles in the event of a worldwide Avian Flu pandemic. But TamiFlu's ability to respond to the adaptable "Bird Flu" virus is famously uncertain - no doubt which drives a subcurrent of frustration with scientists and their inability to know everything.

Fortunately, things are not as dismal as they appear. In the makings, is what will no doubt be referred to in posterity as the Evolution Revolution, a period that will be marked as a "revolution" in the way major health afflictions are addressed.

Of course, research on the two most important forms of contagious disease, as differentiated by their agents of propogation: bacteria and viruses, is informed principally by Darwin's Theory of Evolution. Evolution is a concept, like Einstein's Relativity Theory, that took some considerable amount of time before it won widespread acceptance and comprehension. It is only for this historical quirk, that these tour-de-force propositions continue to be referred to as "theories" rather than laws. On merit they deserve more, since they have been proven beyond the extent of, say, Newton's Second "Law" of Motion, which, by the way, is wrong.

Today, the Theory of Evolution is undisputed. And unlike the Theory of Relativity, it has had a momentous impact on our day-to-day lives: namely by extending them. Bacteria are single-celled organisms and viruses are even simpler. What they have in common is the fact that they they have the most rapid evolution cycles known. In a matter of weeks, hundreds of generations will have transpired and a new strain, impervious to existing drugs, may be the result. So in disease research, it is vital to develop an accurate model that can forecast mutations in these Wee Beasties, and thereby fuel preemptive medical measures.

The Evolution Revolution is an important revision to the Theory of Evolution that is bound to pay dividends in our ability to stop the spread of contagious diseases. One of the most important tenets in his 1859 Origin of the Species, was Darwin's idea of Natural Selection. This mechanism stipulates the occurence of a myriad of microscopic mutations, many of which go nowhere, but a few of which create successful incremental adaptations that accumulate over the millenia to assume the variegated landscape of life that we have documented in our zoology textbooks with those curiously familiar-sounding Latin names like the Proteobacterium and Escherichia Coli, not to mention that most beloved of species from the Chordata-Hominidum category: Homo Sapiens.

According to natural selection, mutations are supposed to occur completely at random. The proposition was accepted until recently as writ. However, in his 1996 tome, Darwin's Black Box, Michael Behe, a Professor of Biochemistry at Lehigh University, revived the long-forgotten (at least in physical science circles) principle
known as Irreducible Complexity. His research reveals that, while many mutations do in fact proceed at random, there are important exceptions to this rule. For example, the evolution of E. Coli's flagellum, a whip-like tail that propels its miniature master through its soupy world, could not have occured through small and completely random incremental mutations; the intermediate creatures, those between unflagellated and flagellated E. Coli, would not have survived Darwin's cruel and undemocratic "law of the jungle" that presides over nature, singling out her strongest innovations to the exclusion of all others.

Darwin's logic, then, turns out to be fatally flawed: natural selection simply does not square with the survival of the fittest. Indeed, for 137 years we have overlooked the complexity of evolution. Yes, random mutations do occur and are responsible for the small, prosaic changes that are merely one facet of evolution. But now it is clear that the big leaps (the Big Bangs if you will) occur via a more concerted "directed selection", like a composer who directs an orchestra through the emotional highs and lows of a piece while allowing the individual musicians some leeway to produce their music.

Unlike the Theory of Relativity, whose acceptance had no immediate human impact apart from philosophical, it is imperative that this extension to the Theory of Evolution be implemented rapidly. The National Institutes of Health as well as most State Boards of Education are notorious for their inability to adapt to important
new scientific standards. In the long run, much of human ailment will indeed be relegated to obsolescence. But the question is: How many people must die and suffer before that happens?

America has always had a remarkable penchant for innovation and once more it is poised to lead a brave new world, this time in the field of medicine. By doing two things, we can ensure that this happens sooner rather than later. First, we ought to train our young minds in the latest scientific developments because they are the future of medical research. Second, we ought to rearrange our taxpayer funded research priorities. This will require a major overhaul of the archaic beaurocracy at the NIH so that research grants give priority to promising research on directed selection; while proposals premised exclusively on natural selection should be cut. The latter move will have the more immediate effect: instead of building stockpiles of dubious drugs like TamiFlu, we will be comforted to rely upon more perspicacious pharmaceutical remedies made possible by Intelligent Design.

Aren't you overlooking the positive side of pandemic? Like war, it drastically reduces population, providing more elbow room for the surviving young minds. These survivors are also, according to ol' Natural Selection Theory, better adapted to life in our rapidly-changing environment. As others have said before me, 'To make an omelette, ...'

If we can regulate disease, then we can probably regulate population without help, thank you very much.

Newsweek must have read my blog because they have put the "Evolution Revolution" on their cover!
