Evolution Defended

The New Republic is publishing an extensive article on The Case Against Intelligent Design. The article provides everything you ever wanted to know about evolution, including the scientific aspects and political background for all previous and current attacks. There’s far too much material to provide the highlights, but this quote might serve as a good introduction to the article:

Intelligent design, or ID, is the latest pseudoscientific incarnation of religious creationism, cleverly crafted by a new group of enthusiasts to circumvent recent legal restrictions. ID comes in two parts. The first is a simple critique of evolutionary theory, to the effect that Darwinism, as an explanation of the origin, the development, and the diversity of life, is fatally flawed. The second is the assertion that the major features of life are best understood as the result of creation by a supernatural intelligent designer. To understand ID, then, we must first understand modern evolutionary theory (often called “neo-Darwinism” to take into account post-Darwinian modifications).

It is important to realize at the outset that evolution is not “just a theory.” It is, again, a theory and a fact. Although non-scientists often equate “theory” with “hunch” or “wild guess,” the Oxford English Dictionary defines a scientific theory as “a scheme or system of ideas or statements held as an explanation or account of a group of facts or phenomena; a hypothesis that has been confirmed or established by observation or experiment, and is propounded or accepted as accounting for the known facts.” In science, a theory is a convincing explanation for a diversity of data from nature. Thus scientists speak of “atomic theory” and “gravitational theory” as explanations for the properties of matter and the mutual attraction of physical bodies. It makes as little sense to doubt the factuality of evolution as to doubt the factuality of gravity.
