Darwin exhibit in at the American Museum of Natural History. Screenshot from exhibit web site. Its best-known exponent was English theologian William Paley, creator of the famous watchmaker analogy. If we find a pocket watch in a field, Paley wrote inwe immediately infer that it was produced not by natural processes acting blindly but by a designing human intellect.

Likewise, he reasoned, the natural world contains abundant evidence of a supernatural creator. The argument from design, as it is known, prevailed as an explanation of the natural world until the publication of the Origin of Species in In some circles, however, opposition to the concept of evolution has persisted to the present.

These antievolutionists differ from fundamentalist creationists in that they accept that some species do change but not much and that Earth is much more than 6, years old. Like their predecessors, however, they reject the idea that evolution accounts for the array of species we see today, and they seek to have their concept—known as intelligent design—included in the science curriculum of schools.

ID is getting a hearing in some political and educational circles. Most biologists have concluded that the proponents of intelligent design display either ignorance or deliberate misrepresentation of evolutionary science. Yet their proposals Significant challenge essay mit getting a hearing in some political and educational circles and are currently the subject of a debate within the Ohio Board of Education.

The section concludes with an overview of the intelligent-design movement by a philosopher and cultural historian who has monitored its history for more than a decade.


The Challenge of Irreducible Complexity: Every living cell contains many ultrasophisticated molecular machines. Intelligent Design position statement By Michael J. To Charles Darwin and his contemporaries, the living cell was a black box because its fundamental mechanisms were completely obscure.

We now know that, far from being formed from a kind of simple, uniform protoplasm as many nineteenth-century scientists believedevery living cell contains many ultrasophisticated molecular machines.

Does natural selection account for complexity that exits at the molecular level? How can we decide whether Darwinian natural selection can account for the amazing complexity that exists at the molecular level? Some systems seem very difficult to form by such successive modifications—I call them irreducibly complex.

An everyday example of an irreducibly complex system is the humble mousetrap. It consists of 1 a flat wooden platform or base; 2 a metal hammer, which crushes the mouse; 3 a spring with extended ends to power the hammer; 4 a catch that releases the spring; and 5 a metal bar that connects to the catch and holds the hammer back.

All the pieces have to be in place before you catch any mice. Natural selection can only choose among systems that are already working so irreducibly complex biological systems pose a powerful challenge to Darwinian theory.

Irreducibly complex systems appear very unlikely to be produced by numerous, successive, slight modifications of prior systems, because any precursor that was missing a crucial part could not function.

Natural selection can only choose among systems that are already working, so the existence in nature of irreducibly complex biological systems poses a powerful challenge to Darwinian theory. We frequently observe such systems in cell organelles, in which the removal of one element would cause the whole system to cease functioning.

The flagella of bacteria are a good example. They are outboard motors that bacterial cells can use for self-propulsion.

They have a long, whiplike propeller that is rotated by a molecular motor. The propeller is attached to the motor by a universal joint. The motor is held in place by proteins that act as a stator. Other proteins act as bushing material to allow the driveshaft to penetrate the bacterial membrane.

Dozens of different kinds of proteins are necessary for a working flagellum. In the absence of almost any of them, the flagellum does not work or cannot even be built by the cell. Constant, regulated traffic flow in cells is an example of a complex, irreducible system. Another example of irreducible complexity is the system that allows proteins to reach the appropriate subcellular compartments.

In the eukaryotic cell there are a number of places where specialized tasks, such as digestion of nutrients and excretion of wastes, take place. This constant, regulated traffic flow in the cell comprises another remarkably complex, irreducible system.

All parts must function in synchrony or the system breaks down. Still another example is the exquisitely coordinated mechanism that causes blood to clot. Molecular machines are designed. Biochemistry textbooks and journal articles describe the workings of some of the many living molecular machines within our cells, but they offer very little information about how these systems supposedly evolved by natural selection.

Many scientists frankly admit their bewilderment about how they may have originated, but refuse to entertain the obvious hypothesis:Home / College Discussion / Colleges and Universities / CC Top Universities / Massachusetts Institute of Technology.

The best-known kind of weather modification is cloud seeding, with the goal of producing rain or snow, suppressing hail (which can ruin crops), or weakening hurricanes. This essay is a companion to my earlier essay, Weather Modification Law in the USA, which concentrates on.

If a single problem has vexed biologists for the past couple of hundred years, surely it concerns the relation between biology and physics. Many have struggled to show that biology is, in one sense or another, no more than an elaboration of physics, while others have yearned to identify a “something more” that, as a matter of fundamental principle, differentiates a tiger — or an amoeba.
