Heuristic Value of Design vs Evolution
An article entitled “Architectural Analysis and Intraoperative Measurements Demonstrate the Unique Design of the Multifidus Muscle for Lumbar Spine Stability,” in the current issue of the Journal of Bone and Joint Surgery, nicely refutes Dobzhansky’s pontifical pronouncement that “nothing in biology makes sense except in the light of evolution.”
The abstract is available online, though the full text article requires a subscription. This errant concept has been discussed previously on UD by DonaldM, but I thought it worth revisiting when I saw this example of the absolute lack of any usefulness of any concept of evolution in understanding at least this type of biological form and function.
The most striking thing about this article from a heuristic standpoint is that understanding the muscle under study depends completely on a design perspective, and owes nothing to any understanding of evolution. This is implicity acknowledged by the authors in the wording of their descriptions and conclusions:
“The architectural design … demonstrates that the multifidus muscle is uniquely designed as a stabilizer to produce large forces.”
