RE: That information is subject to change, change is in fact inevitable.
Yes, but is it DARWINIAN EVOLUTION ? I change and in fact am changing -— from better to worse as my health deteriorates. That is hardly Darwinian Evolution. I call it devolution ( for want of a better word ).
A new variation of the bacterial Penicillinase enzyme that binds Methocillin under conditions that select for Methocillin resistance is “DARWINIAN EVOLUTION” in that it exhibits precisely his theory....
Evolution through natural selection of genetic variation. In this case a “descent with modification” that is a useful modification that is a “gain” of information - the information on how to ‘disarm’ Methocillin.
