Here's something that I've wanted to know because it's related. Where exactly is the "3D geometry data" that defines for example, the shape of your skull, located? If cells need to differentiate themselves into structures like that, where is that specified? Sounds like membrane patterns and microtubule arrays according to Wells. But if those only come about under DNA control, then it's back to the DNA. But DNA doesn't hold "shape data" does it?
What makes you think that DNA doesn't hold "shape data"? My head looks like my Dad's head - except where it doesn't. Then it looks like my Mom's head. So I have my Dad's forehead, my Mom's jaw and my nose is somewhere in between. I can see the same thing in my daughters. Oldest daughter has my forehead and also over sized head - too bad for her, youngest daughter has my wife's forehead and normal sized head. Obviously DNA does control "shape data". Wells is full of crap.
Note - Just because we cannot necessarily identify WHICH gene or genes control head shape doesn't mean they aren't there. We see the results. Why should shape be any less likely to be under gene control than any other characteristic? Distinct lack of logic here.
