Intelligent design is harder than it looks

Several biotech firms have been trying to make a substitute for human blood to be used in emergencies when donated blood isn’t available.  The first generation of products proved so toxic that the Food and Drug Administration took them off the market.  It turns out that one of the functions of red blood cells is to prevent iron-rich proteins from attacking the kidneys.  Blood substitutes did not have this necessary cellular structure.  They just infuse oxygen-carrying compounds into the blood which, in too many cases, did more harm than good.

One of the stronger arguments to be made for intelligent design by a superhuman Agent is that human designers haven’t been able to compete with him.  Even in a living subject with functioning lungs, heart, and vascular system, the task of carrying oxygen in and carbon dioxide out has proved too difficult to imitate.  We wish the biologists and chemists well in their endeavor and hope they’re able to invent something that can save lives and help prevent the spread of HIV/AIDS.  God might be inclined to disclose his secrets a bit more readily if men would acknowledge he did an awfully good job of creation in the first place.  Hemoglobin was a good idea.  But what kind of genius thinks of putting it inside free-floating protective cells?
