Today is the 200th anniversary of Charles Darwin, author of the Origin of Species and The Descent of Man, and commonly ascribed as the father of evolutionary thought. Evolutionary ideas had been alluded to by several philosophers and early biologists including Darwin’s own grandfather Erasmus Darwin. A paper containing a similar theory of natural selection by a contemporary biologist Alfred Russell Wallace convinced him to publish his seminal work. But, the comprehensive nature of the argument accompanied by detailed observations meant that, despite the modest competition, the theory of evolution by natural selection laid out by Darwin in The Origin of Species has gone down as ‘the single best idea anyone has ever had’.
Charles Darwin born in 1809
The beauty of Darwin’s theory of evolution is the elemental simplicity that describes the seemingly infinite complexity of the history of life on earth. Over hundreds of millions of years life transformed from the simple combination of a protozoan and a bacterium into the whole cornucopia of life that inhabits almost every conceivable part of our planet today, via the existence of everything that ever lived, ever. Its genius is that all that can be explained by a simple process of selection of minute genetic differences which increase the survival chances of that gene in a world of scarce resources and fearsome competition. Over many generations the combination of many small changes and their impact on the survivability of the host and therefore its genes leads to the emergence of new traits, new behaviours and eventually new species.
As a scientific concept Darwinian evolution has received universal acceptance and has underpinned the whole study of evolutionary biology and is a unifying principle in the biological sciences, much like Newtonian laws of gravity underpin the physical sciences.
Darwin as the founder of evolutionary biology had the misfortune of knowing less than all subsequent evolutionary biologists. There remains much legitimate debate concerning the actual processes and patterns of evolution. But subsequent discoveries of molecular genetics and numerous examples from the fossil record have shown the emergence of new species, transitional forms between known species and animal groups all occurring in exactly the way and by the exact method Darwin described. Fifty years after the publication of Darwin’s theory (and in the year of his 100th anniversary) there was still considerable doubt as to its legitimacy. But, as concurrent theories such as Lamarckian inheritance have been debunked, a further 100 years later we can now say that the evidence is overwhelming and there is no conceivable scientific alternative.
Unfortunately this scientific acceptance of Darwin has not been matched by public acceptance. The original publication of Darwin’s theory caused a huge outcry from the contemporary scientific and religious establishment. As scientific knowledge of biology has progressed legitimate scientific criticism has faded away. But, Darwinian evolution is still the target of religious attacks based on ardent belief, flawed and evasive arguments and misrepresented or bad science.
Natural selection creates a perfectly comprehensible and effectively simple explanation for the whole evolution of life with no need for external intervention by supernatural forces, omnipotent creators and intelligent designers. Evolution’s implicit threat to religion is that it demystifies the apparent miracle of life to a process of random chance driven by ruthless selection often caused by acts of remarkable violence. Evolution does not disprove the existence of gods but it really demarcates their area of operation. This threat has inspired an ongoing campaign which has created the allure of controversy and debate where there is none, and prevented Darwin from gaining the universal acceptance that he should. In recent years this religious assault has tried to assume a quasi-scientific cover with the theory of intelligent design.
I commented earlier that their is no conceivable alternative theory to describe the complexity of life. Intelligent design fails due to its adherence to supernatural forces in the action between designer and designed (or should that be creator and created). Some ID advocates have said that the exclusion of ID from the scientific lexicon on this basis is evidence of some convoluted arrogance and sinister atheisitic scientism. It is actually as a result of scientific method requiring hypothesis, experimentation, reproduction and then acceptance. ID by definition has only one being capable of experimentation. However, there is no clear consensus around many of ID’s arguments and no unifying theory to describe its processes. Most ID argumentsare flawed and misrepresented criticisms of evolution and rather than explaining these alleged flaws with an alternative scientific explanation they use them as proof of a supernatural intervention.
Much of the evidence to support Evolution (but by no means all) comes from the fossil record. At the time of the publication of The Origin of Species that record was a fraction of the size it is today and corresponding theories of geology were similarly underdeveloped meaning it was very unclear how old it actually was. We now know that this fossil record covers hundreds of millions of years. This record is also not a complete record of all life on earth. Only a tiny fraction of living organisms will die in the exact conditions that will favour preservation as fossils and only a tiny fraction of them will be discovered. Hard structures like bones, teeth and claws lend themselves much better to fossilisation than less robust structures like scales, skin and feathers.
The fossil record has alwasy been used as the stick to beat evolution and in Darwin’s day these accusations were far more credible. This record is now far more expansive and exclusively supports that theory. The apparent sudden appearance of complex forms in the Cambrian era has been shown to have happened over 35 million years and the hard and bony creatures that evolved at that time are much more likely to fossilise than the soft bodied creatures that preceded them. We now see extensive evidenceof complex life in the Pre-Cambrian seas in the fossil record. It is rarer because it is inevitably older and deeper and made up of species not conducive to fossilisation but it is there.
An absence of transitional forms in the fossil record caused Darwin much soul searching in his own lifetime. Now the fossil record is littered with transitional forms between species. The evolution of horses has over thirty transitional formsto link modern Equus to its earlier mammalian ancestors. Indeed some arguments state that transitional forms are seen in the higher taxa but not in more primitive forms, it is unclear why the designer would have designed some species to evolve and others to remain stable. Fossils like Archaeopteryx and Tiktaalik are clear evidence of special emergence between great animal kingdom groups and proponents of design have had to resort to clumsy reclassification into one group or another or making accusations of elaborate hoaxes.
The continuation of this argument is that the fossil record shows species in a stable state for millions of years. This is an inevitable result of evolution by natural selection. Increased mortality driven by changing circumstances, and concurrent scarcity of resources and competition for them, is the prime driver to the emergence of new forms. If a species inhabits an environment to which it is well suited with little competition for resources it will propogate and survive. With more offspring there will be a greater impact on the fossil record. The fossils we find are much more likely to show evolutions winners.
ID advocates also point to so called ‘living fossils’ or organisms alive today which appear in the fossil record in an apparently identical form hundreds of millions of years ago. Whilst this clearly demonstrates ancestry in many cases the fossilised specimen is not the same species. These are merely two closely related species with a highly successful collection of genes wll adapted to their environments and robust enough to weather the ravages of geological time. The many species of Crocodiles today are not the same as the first species of Crocodylidae to appear in the fossil record 200 million years ago.
Advocates of intelligent design make their trade by misrepresentation of scientific method and avoidance of scientific fact. They state that they merely wish to debate the controversy where none exists and then try and use that as a controversy that needs to be debated. They see evolution as having to prove itself every step of the way, explain every anomoly, justify every feature observed in taxonomy (which it does surprisingly well) and offer only a devotional faith in an ethereal puppet master as an alternative. They ascribe design to every living organism and see no need to explain by what process it was designed or, for what purpose. Their view of the world is that it is too complicated to be understood and therefore god did it. Luckily 200 years ago someone was born who didn’t accept such an elementary view of life.
Happy birthday Charles, and thanks for the single best idea anyone has ever had.


Attacks on evolution and the right wing’s social agenda

Science vs. ‘intelligent design’
Monday, Feb. 12, was celebrated as “Darwin Day” by schools and other institutions in the United States. Scientist Charles Darwin was born on that day 198 years ago. This article about Darwin and right-wing attacks on his theories was first published in the December 2005 issue of Socialism and Liberation magazine.
A recent court case in Pennsylvania brought the right wing’s attacks on science into the public spotlight. The case is the tip of the iceberg in a well-funded effort to promote religious ideology at the expense of scientific and rational thinking.
The Harrisburg, Pa. case involved the legality of referencing “intelligent design” in public school biology classrooms.
Charles Darwin (1809-1882), originator of the theory of evolution.
“Intelligent design” is a code phrase for the anti-scientific idea of a god creating life. The movement asserts that only an unknown designer—not evolutionary processes—can explain the development of life on earth and the biological complexity of the natural world.
The case comes from a 2004 decision by a Dover, Pa., school board requiring biology teachers to read a four-paragraph statement telling students that “gaps” existed in current evolutionary theory and that “intelligent design” was a reasonable alternative worth exploring. Eleven parents sued the school board, calling the statement a violation of the separation between church and state and a thinly veiled attempt to reintroduce a faith-based concept of “God” into the natural sciences.
Attorneys presented final arguments for the case on Nov. 5.
A brief exposition of the political forces and “scientific” premises behind the intelligent design movement shows that the parents’ accusations are correct. The Harrisburg trial has not received national attention because of Dover’s renegade school board, all of whose members were voted out on Nov. 8. At the root of the trial and the entire intelligent design “controversy” is a far-reaching, right-wing attack on the fundamental methods and premises of modern science.
It is an attempt to roll back more than a century of scientific thinking and progress with implications that go far beyond biological theories.
Science and evolution
The main issue in the Harrisburg case was whether intelligent design represents religion or science. In common definitions, a theory is accepted as scientific when it is consistent, testable, correctable, progressive (meaning it builds off of previous discoveries) and based on controlled, repeated experiments.
Every high school science class learns about the scientific method, which is the cornerstone of every scientific theory. This method begins with observations of natural phenomena. Then reasoning is used to generalize from the observations to make theoretical models capable of making predictions about future observations. These predictions are then tested in experiments and results are collected. Once the results can be reproduced consistently, the hypothesis becomes a theory.
Science attempts to arrange observations of the natural world into rational laws that allow us to understand that world more completely without resorting to forces outside of nature itself.
This is an important feature of evolutionary theory. In 1859, Charles Darwin published “The Origin of Species,” which elaborated the theory of evolution by natural selection. That theory says that over time, biological populations change according to the capacity of certain individual organisms to adapt to their environment. Darwin explained this adaptation as a result of the chance variations of the organism’s individual traits.
The organisms that survive are able to reproduce. As the changes accumulate over generations, new species arise—those that are best able to adapt to their natural environment. The conditions of the natural world—not humans or any god—determine which species survive.
One aspect of Darwin’s theory is “common descent,” which means that all living things come from a common gene pool or ancestor. Over billions of years, this common pool has split into various families and species.
One can see evidence of common descent in the traits shared by all living organisms. In Darwin’s time, he was only able to make this argument with visible observations, comparing the anatomy of various species. For instance, even birds that do not fly have wings—suggesting that birds come from a common ancestor.
Darwin’s theory was incomplete, lacking an explanation of how certain traits were inherited or the source of variations among individual organisms. In the 1930s, however, scientists used their knowledge of genetics to update and improve evolutionary theory. The discovery of DNA was a stunning confirmation of evolution and common descent. Every living thing has nucleic acid as its genetic material with the same 20 amino acids as the building blocks for proteins.
The explanation for variations was given when scientists discovered that a whole variety of genetic mutations regularly occur in cell division and other biological processes.
Far from being an unchanging belief system, evolutionary theory has been tested against biological and archeological facts, revised and improved time and again.
The ‘god of gaps’
Does intelligent design hold up to these same scientific standards? The National Academy of Sciences regards evolutionary theory as the bedrock of modern biology. It recommended that intelligent design “and other claims of supernatural intervention in the origin of life” not be treated as science. (“Science and Creationism,” 2nd ed., 1999)
Although intelligent design advocates have different names for their arguments—”irreducible complexity,” “specified complexity,” and the “fine-tuned universe”—they all can be reduced to the same premise: since organisms are so complex, and so “perfectly put together” in ways that evolution cannot fully explain, someone or some thing must have designed them.
Evolution is a general theory that provides a framework for explaining the development of different species. How each individual species and mutation arises and fits into the evolutionary framework is an active area of scientific work.
Intelligent design advocates seize on phenomena that have not yet been explained by evolutionary theory as evidence for the work of a godlike being. According to them, every unexplained detail—for instance, a genetic variation that happened millions of years ago—can only be explained by some divine or supernatural intervention.
For this reason, critics have called intelligent design the “god of gaps,” whereby its advocates use “God putty” to fill in every perceived crevice in accepted theories. This is not science. Instead of making conclusions based on what is observed, it makes conclusions based on what cannot be observed. It cannot be tested or corrected.
It is also bad logic. Why begin with the assumption that complexity requires conscious design and cannot develop according to its own internal laws? Why can there not be just some things we have not figured out yet? And if every complex thing must have a designer, who designed this intelligent designer?
In short, intelligent design requires faith. It breaks down once it is subjected to any serious scientific interrogation. It should be no surprise, then, that intelligent design advocates do not put their articles up for peer review. They keep their advocacy campaigns on the editorial and opinion pages.
The forces at play
Although the spokespeople for the intelligent design movement include a few scientists, it is above all a political and
religious movement. Scientists have called it “creationism in a lab-coat.”
Since 1990, the Discovery Institute, a right-wing think tank, has championed intelligent design. It gives lucrative scholarships to individual scientists willing to give a cover of legitimacy to their anti-science schemes. Far from any aspirations to improve science, their own documents reveal an intention to use intelligent design to “reverse the stifling dominance of the materialist worldview … and replace it with a science consonant with Christian and theistic convictions.” (Knight Ridder News Service, Oct. 16, 2005)
Their widely publicized strategy is called the “wedge strategy,” which aims not to take evolutionary theory head-on in the field of science (where they admit they will lose), but to simply “teach the controversy.” In other words, by appealing to “critical thought” and “free discussion,” they hope to win policy-makers and the general public over to the idea of presenting evolution as one of a variety of explanations for the development of life.
The creators of the deceitful “wedge strategy” consciously avoid Biblical references and have tried to avoid any lawsuits that would put the legal system officially on record against intelligent design. In the 1980s, a school of “creation science” emerged, which attempted to have the flood of Noah’s Ark taught as a viable explanation for the world’s present geological makeup. When geologists universally rejected the view, the courts barred the teaching of the creation pseudo-science, and set the right-wing movement back.
Learning from the experiences of their predecessors, the stated goal of the Discovery Institute’s sub-division, the Center for Science and Culture, is to have “design theory permeate our religious, cultural, moral and political life” by 2018. According to a document released by a member of Kansas Citizens for Science at a June 2001 conference, the Center’s five-year objectives include: “One hundred scientific, academic and technical articles by [Discovery Institute] fellows,” “significant coverage [of intelligent design] in national media,” and “ten states … [rectify] ideological imbalance in their science curricula.”
The right wing on the move
So far, thanks to heavy funding and right-wing political support, the Discovery Institute has been effective. By simply putting intelligent design on the map and stirring up a controversy—which does not exist in the science community—the movement has gained wide exposure.
Appealing to the continued lack of scientific background among the U.S. public, the movement has won new supporters. Meanwhile, many Republican leaders, including President Bush, have endorsed intelligent design. (Associated Press, Aug. 2, 2005)
The rightists are not devoting so much time and energy to the intelligent design campaign for academic reasons, much less the interest of truth or science. They are aiming to strengthen the ideological position of Christian fundamentalism, an essential tool in providing the billionaires and generals with a semblance of a mass base.
It is part of the effort to roll back women’s reproductive rights. It is part of the effort to prevent the lesbian, gay, bisexual and transgender communities from winning any basic democratic rights. It is part of the effort to demonize the Arab and Muslim people to gain support for U.S. imperialism’s military adventures in the Middle East.
Karl Marx dedicated his economic masterpiece, “Capital,” to Charles Darwin. That was not because Darwin was a communist or a political activist. Instead, Darwin’s theory provided a materialist analysis of the development of the natural world, devoid of superstition or religious prejudice. Just as Darwin discovered that species developed according to their struggles and interactions with the world around them, Marx applied a similar scientific method to the development of human societies. What Darwin did for natural sciences, Marx did for social sciences.
Socialists protect the tradition of materialist thought, which uses scientific examination and not some supernatural force to explain how the world works.
