Intelligent Design (brief overview).

RE: Intelligent Design (brief overview).
Put the stupid fucking koran down and learn something.

Quote:When anti-evolutionary arguments featuring the bacterial flagellum rose into prominence, beginning with the 1996 publication of Darwin's Black Box (Behe 1996a), they were predicated upon the assertion that each of the protein components of the flagellum were crafted, in a single act of design, to fit the specific purpose of the flagellum. The flagellum was said to be unevolvable since the entire complex system had to be assembled first in order to produce any selectable biological function. This claim was broadened to include all complex biological systems, and asserted further that science would never find an evolutionary pathway to any of these systems. After all, it hadn't so far, at least according to one of "design's" principal advocates:

Quote:There is no publication in the scientific literature – in prestigious journals, specialty journals, or books – that describes how molecular evolution of any real, complex, biochemical system either did occur or even might have occurred. (Behe 1996a, 185)

Quote:As many critics of intelligent design have pointed out, that statement is simply false. Consider, as just one example, the Krebs cycle, an intricate biochemical pathway consisting of nine enzymes and a number of cofactors that occupies center stage in the pathways of cellular metabolism. The Krebs cycle is "real," "complex," and "biochemical." Does it also present a problem for evolution? Apparently yes, according to the authors of a 1996 paper in the Journal of Molecular evolution, who wrote:

Quote:"The Krebs cycle has been frequently quoted as a key problem in the evolution of living cells, hard to explain by Darwin’s natural selection: How could natural selection explain the building of a complicated structure in toto, when the intermediate stages have no obvious fitness functionality? (Melendez-Hevia, Wadell, and Cascante 1996)

Quote:Where intelligent design theorists throw up their hands and declare defeat for evolution, however, these researchers decided to do the hard scientific work of analyzing the components of the cycle, and seeing if any of them might have been selected for other biochemical tasks. What they found should be a lesson to anyone who asserts that evolution can only act by direct selection for a final function. In fact, nearly all of the proteins of the complex cycle can serve different biochemical purposes within the cell, making it possible to explain in detail how they evolved:

Quote:In the Krebs cycle problem the intermediary stages were also useful, but for different purposes, and, therefore, its complete design was a very clear case of opportunism. . . . the Krebs cycle was built through the process that Jacob (1977) called ‘‘evolution by molecular tinkering,’’ stating that evolution does not produce novelties from scratch: It works on what already exists. The most novel result of our analysis is seeing how, with minimal new material, evolution created the most important pathway of metabolism, achieving the best chemically possible design. In this case, a chemical engineer who was looking for the best design of the process could not have found a better design than the cycle which works in living cells." (Melendez-Hevia, Wadell, and Cascante 1996)

ID is creatardism in a new package.  Your phony god had nothing to do with any of it and you had best accept reality and move on.
