Early embryology; clockwork construction plan (Introduction)

It all brings me back to one of my hobbyhorses. Once we strip the word â€œmutationsâ€ of its association with â€œrandomnessâ€, isnâ€™t this a view of evolution that might be acceptable on both sides of the fence? The theist can carry on claiming that the mutations have been coded into the Hox mechanism (or the UI has intervened), while the atheist can carry on claiming that they have come about through chance and/or environmental pressures. I certainly find this scenario immeasurably more convincing than the creationist insistence on separate creation, and Dawkinsâ€™ â€œsmooth gradient up Mount Improbableâ€.

Your hobbyhorse creates more problems if it backs up. Where in the world would a master Hox gene come from to coordinate the formation of a single-celled organism to launch life? The genes we have now started somehow! I don't think I've seen a paper describing a Hox gene for epigenetic changes to the genome, but just what does control that area of genome activity?
