I think using DNA, microbiology and genetic engineering in the evolution-creation catfight is a wate of time. It bores me.
Yes, whichever side I embrace is irrelevant, as is anyone else's faith, whatever form it takes.
BUMP!
I appreciate the clarification on what you are seeking.
That being the case I think you would profit from reading "Endless Forms Most Beautiful" as that goes into great detail on the interaction of genes, homeoboxes, DNA, tool kits, switches and repressors. These mechanisms have been discovered in the process of mapping every nook and cranny. Without understanding them and how they operate, it is not possible to understand the limits and possibilities of genetic engineering. The author has been involved in the core research involving discovery of these basic processes, some knowledge of which is only several years old.
