Now, carrying the biological metaphor one step further, epigenetics tells us we can take that set of genes and short circuit some, duplicate others, delete yet others and lo and behold we end up with entirely new functions and processes that still contribute mightily to the existence and success of the organism.
Alas, it's relatively new science ~ maybe 5 years old ~ maybe less ~ but it knocks the stuffings out of all the DNA metaphors!
God in His infinite wisdom knows what He's doing!
Amen! God IS in control and He knows His own.
