If you don't understand that "micro" and "macro" evolution are the completely different, you've no business engaging in a discussion of evolution.
Micro evolution is the e.coli examples you've cited, with variations developing within a species in response to environment or random chance.
But the species remains e. coli, no matter how long it's been in existence.
Macro evolution is the development of a new species through changes to an earlier species, an alleged example bein ape to man.
Macro evolution is a term used by Young Earth Creationist in an attempt to deny the greater reality of evolution.
By definition "Macro Evolution" is just evolution on a geologic time scale. So if you grant micro evolution, but deny macro evolution, you are by default denying the existence of geologic time scales, which of course is the position of the biblical literalist YEC's.
Calling "young earth creationists" anyone who makes a distinction between microevolution and macro-evolution is simply a term fundamentalist Neo-Darwinists employ in an attempt to avoid answering the real hard evidentiary questions to which they do not have answers and which their theory is powerless to explain. Micro-evolution is a presently observable and thoroughly proven phenomenon. Macro-evolution by natural selection is an assumption extrapolated from the reality of micro-evolution which assumption is unlikely to be true and is contradicted by a mass of evidence. Rather than confront the discontinuity and contradictions, fundamentalist Neo-Darwinists employ ad hominem invective in a desperate effort to deflect scrutiny from the very real problems in their theory. Their pre-existing fundamentalist religious commitments (atheism) demands if of them.
