Hi J Patterson, and welcome to EvC,
Does anyone seriously believe that every last detail of human anatomy (from toenails to hair), physiology, and supposedly genetically determined behavior could fit in 200 textbooks?
No, no-one believes that. The genome does not even specify things like how exactly your blood vessels are routed, or how precisely the connections of the optic nerve are arranged between your eyes and your brains. What it contains are the
mechanisms (note: mechanisms - not information, not instructions) that allow a human body to grow under the circumstances in which it grows.
Take a gene that codes for a protein - the major part of the genome that we understand - the genome only produces the sequence of amino acids within that protein, the three-dimensional structure of the protein and the way in which it interacts with its ligands is provided not by the genome* but by the laws of Chemistry and Physics.
The genome is, supposedly, the mechanism of evolution. If this mechanism isn't valid, if there's not enough room on the DNA, then evolution collapses. We don't just have a designer, we have a CREATOR.
Are you suggesting that God continually tampers with the biology of every organism on earth in order to make it work?
* - actually it's a bit more complicated than that.
