It seems like Professor David Gelernter is only just referencing Stephen Meyer's work.
I don't think invoking the lack of transitory fossiled ancestors in the Cambrian explosion really goes against the main principles of Darwinism. It seems like more of an argument against certain statements made by Darwin about evolution being progressive or an incremental process while nothing in the mathematics of evolution necessarily implies changes in the anatomical domain of a species can't be, for example, from one small genetic change which can have a relatively, "large" change in their morphology and structure.
And also, it is not like punctual equilibrium among other theories and unknown variables are not a viable consideration in explaining the lack of fossils in the cambrian explosion, no? I don't think they have to immediately go to intelligent design(from their standards of logic).
To be even more controversial (but it's a fun read no matter what you make of it) ;-):
In the NPMR interpretation in that link, McMoneagle's interpretation of a bipedel, proto version of humans existing in the shoreline seems to correspond with an account of the origin of species from someone in the explorer series of the monroe institute who says that species also existed on the shoreline and were aquatic to an unknown degree, among other details. This reference to an aquatic phase in our evolution might explain the lack of hair in humans relative to other apes, our thick subcutaneous fat-layer, stretched hindlimbs, voluntary respiration, etc. - while we are having fun with this idea.
Also in that link, directed panspermia by Francis Crick could be plausible. There is a significant biological importance to oxidized molybdenum in the organic processes of the organisms of earth, yet molybdenum is a rare element on earth. Despite being postulated as crucial to the origins of life, around 3 billion years ago, earth had very little oxygen and the oxidized version could not have been available, according to a study. Same thing with boron but at a time when the earth was likely to have been covered totally by water which would have prevented sufficient concentrations of boron forming while water is also corrosive to RNA. Meanwhile, oxygen and dryland with water were available on Mars, not on earth. It is possible that life began on molybdenum/boron rich environments and was transmitted to Earth through panspermia, whether directed or not.
