In looking at proportional development we see the kind of specificity and complexity that makes arguing for design easy.
"Instead of discounting the variability of the Bicoid gradient among different embryos, we found this noise to be an advantage of the system," said Dr. Ma, also a professor of pediatrics at the University of Cincinnati College of Medicine. "The amount of Bicoid going to small and large embryos all self corrects, so the system is built to be very robust and precise so different cells can be told to become part of the head, or part of something else, in a proportionate manner."
