The great divide…

[ratings]

IN geographic terms, the ‘great divide’ is used to define the point in the USA, roughly following the course of the Rocky Mountains, where on one side a drop of water will run down into the Pacific Ocean, and on the other, it will run down into the Atlantic.

There is however another great divide in the USA, which is between those that have a basic knowledge of the world around them, and those that don’t. The online newszine Science Daily described a recent poll commissioned by the California Academy of Sciences, in which a series of basic questions, designed to assess basic science literacy, were posed to 1,002 adults over a four day period last December. The poll has been ongoing (though in a less rigorous sense) online at the CAS website. The results were as follow:

  • Only 53% of adults know how long it takes for the Earth to revolve around the Sun [a year, 365 days]
  • Only 59% of adults know that the earliest humans and dinosaurs did not live at the same time. [Duh]
  • Only 47% of adults can roughly approximate the percent of the Earth’s surface that is covered with water. [where the answer of 65-75& was taken as approx. correct, though 15% gave the correct response of 70%]
  • Only 21% of adults answered all three questions correctly.[!]
  • Less than 1% of U.S. adults know what percent of the planet’s water is fresh [3%]

Hands up who thinks this is unacceptable?

No, it’s not. So why is the USA finding it has a problem with scientific literacy? Well, please just indulge me. Let’s think about Pakistan, where many (though not all) Madrassas (Islamic schools) are engaging in the indoctrination of a new generation of children into fundamentalist rhetoric; this comes at the cost of education that can raise people out of poverty and morbidity; education that gives them some control over their lives. However, for many, Madrassas are the only source of ‘education’. Yet if you speak to a young professional on the street of moderate urban centres such as Karachi, they are not going to present you with the fundamentalist hard-line; they are the lucky few, to have been born into a better area, perhaps to a richer family whom are well educated.

It is not such a great step to see such a partisanship developing in the USA, with the richer, well educated ‘elite’ being outnumbered by those who are disenfranchised from modern successes, scientific discoveries and societal benefits. Those left behind in progress increasingly turn inward toward timeless stalwarts such as the fundamentalist hard-line, which not only serves to widen the gulf to be crossed by communicators of science, but ultimately results in senators, congressmen and governors becoming willing to bow down to public anti-science opinion, i.e. votes, at a government level, thus jeopardising the future scientific and medical progress.

“Two plus two makes five” – Winston Smith, 1984.

IF enough people believe it, or if it is illegal not to believe it, will it be true?

I spend a lot of my time, probably too much, waging a battle of wits and reason with the truly and irredeemably unreasonable. The usual subject is the scientific theory of evolution. I preface the noun “theory” with scientific so as there is no mistaking exactly what we mean by theory.

Whenever I hear the words “Just a theory….” levied at a scientific theory, it sends a shudder down my spine. As I’ve mentioned before, and I will undoubtedly continue to do so, a scientific theory is not speculation or opinion, it is a comprehensive, logical and above all testable model that represents the best means of explaining the evidence. Furthermore it facilitates predictions that can be tested experimentally to continue to verify the reliability of the theory. The theory of evolution is just such a theory:

The theory of evolution explains that variation exists between individuals within a species, it explains how natural selection can act to drive this variation and it shows how, and describes why, some organisms display characteristics that make them better suited, i.e. fitter, for life in the environment in which they live. It explains how these “fitter” organisms are the ones more likely to survive and pass on their characteristics to offspring. It explains how, over time, these characteristics become a trait in all members of a species, and how less favourable characteristics can be lost. Ultimately, the theory of evolution explains how a species, over this long period of time and subject to much genetic change steered by natural selection, can be very different from its ancestors.

Now, the above paragraph is qualitative, and largely non-technical. However, bound up within the above is some impressively complex science. The debates that rage amongst scientists is not about the validity of the above, it’s about the specifics of how they’re achieved. Part of what I aim to do with this blog is not re-write any of the perfectly excellent books on evolution that are available, but to tackle those areas that are taken advantage of by religious fundamentalists. Science is a dynamic subject; by the time it is written up in a book, it is already out of date. As I mentioned before, there is a battle of wits going on out there, between scientists or other such rational free-thinkers, and religious fundamentalists (which for want of a better term, I call “Fundies”).
