Some readers may know that fierce debates have occurred among intelligent design theorists — mostly behind the scenes — about the causal role of DNA. Without naming names (because blessed are the peacemakers), I can say that I have friends on both sides of these debates. The pro-DNA side argues that nucleic acid is the causally privileged information carrier in all organisms. The DNA-is-cool-but-not-the-whole-story side, by contrast, says not so fast: DNA is important, but naked DNA is an inert molecule. Stone-cold dead, in fact.
These debates go right to the heart of what ID is, or should be, about as a scientific theory in biology. Thus it’s encouraging, REALLY encouraging, to see the work of University of Maryland biologist Antony Jose, who (as far as I know) has no detectable ID sympathies. In an open access paper, Jose tries to understand how the transmission of information in inheritance occurs without making DNA carry the whole burden — because, he argues, DNA simply cannot carry the whole burden. See, “A framework for parsing heritable information,” published in the Journal of the Royal Society Interface.
H/t to Denyse O’Leary for this reference. See here for a popular science take on Jose’s project: “DNA may not be life’s instruction book — just a jumbled list of ingredients.”
