Here are some excerpts from The Plausibility of Life, by Marc W. Kirschner and John C. Gerhart. While reading the book, I find that along the way the types of statements which follow are to be found almost everywhere .
One of the objections (disingenuous, in my opinion) that the Darwinists have to ID is that “we don’t know who the designer is; therefore, how can we possibly identify his designs?†Well the following quotes make it quite clear that the designer’s designs are easily identified. All’s you have to be to detect the design is be a graduate of an engineering school. No wonder lots of ID proponents have engineering backgrounds (including myself.).
Here are just some quotes:
“In this turtle, males are produced at lower temperatures 78° F (26° C) and females at higher, 88° F (31° C), the opposite of the alligator. In a flip-flop circuit, not unlike a thermostat that would gratify any engineer, a small difference in the level of a regulator of estrogen synthesis can be amplified into one of two states, a high-estrogen state (female development) or a low-estrogen state (male development). . . .The result is a bistable switch driven one way or the other by the temperature dependence of the production of SF-1 protein.†(p. 94) . . . .
“In the end, several major refinements had to be added to the bacterial model to explain gene regulation in the much more complicated eukaryotic cells, including humans. . . . A second refinement was the linkage of several transcriptional regulators and genes into complex circuits, including circuits in which certain regulators control the expression of genes encoding other regulators. These circuits can have logical and operational features like those in computers. . . . The logical structure of these circuits is only now being worked out, but they bear strong resemblance to logic circuits in engineering.†(p. 119)
