The Short Answer: Not at all. Intelligent design works off positive predictions about where experience tells us that intelligent design is the cause at work. Furthermore, the "gap" in Darwinian evolution is not a gap in knowledge, but a fundamental theoretical gap that represents an aspect of biology which Darwin's theory is simply incapable of bridging.

The Long Answer:

Intelligent design begins with observations about the types of information produced by intelligent agents. Even the atheist zoologist Richard Dawkins says that intuitively, "biology is the study of complicated things that give the appearance of having been designed for a purpose." Darwinists believe natural selection did the "designing" but intelligent design theorist Stephen C. Meyer notes, "in all cases where we know the causal origin of 'high information content,' experience has shown that intelligent design played a causal role." Meyer also emphasizes many of the positive predictions of intelligent design: "Experience teaches that information-rich systems … invariable result from intelligent causes, not naturalistic ones. Yet origin-of-life biology has artificially limited its explanatory search to the naturalistic nodes of causation … chance and necessity. Finding the best explanation, however, requires invoking causes that have the power to produce the effect in question. When it comes to information, we know of only one such cause. For this reason, the biology of the information age now requires a new science of design.
(Stephen C. Meyer, Mere Creation, pg. 140).

"Indeed, in all cases where we know the causal origin of 'high information content,' experience has shown that intelligent design played a causal role."
(Stephen C. Meyer, DNA and Other Designs)

"Intelligent design provides a sufficient causal explanation for the origin of large amounts of information, since we have considerable experience of intelligent agents generating informational configurations of matter."
(Meyer S. C. et. al., "The Cambrian Explosion: Biology's Big Bang," in Darwinism, Design, and Public Education, edited by J. A. Campbell and S. C. Meyer (Michigan State University Press, 2003) Thus intelligent design theory is not attempting to insert itself into some "gap" but rather it deserves a chance to be heard as a sufficient cause for the origin of complex and specified biological information. We can make positive predictions about how intelligent design theory works based upon our observations of how intelligent agents work:

Table 1. Ways Designers Act When Designing (Observations): (1) Take many parts and arrange them in highly specified and complex patterns which perform a specific function.

(2) Rapidly infuse any amounts of genetic information into the biosphere, including large amounts, such that at times rapid morphological or genetic changes could occur in populations.

(3) 'Re-use parts' over-and-over in different types of organisms (design upon a common blueprint).

(4) Be said to typically NOT create completely functionless objects or parts (although we may sometimes think something is functionless, but not realize its true function).

High information content machine-like irreducibly complex structures are commonly found. The bacterial flagellum is a prime example. Specified complexity found in the laws of the universe may be another.
