What I mean, is that while there are theories of evolution
outside of natural selection (i.e. Grecian theories of evolution from
long ago or Hume's naturalism), the process of natural selection is
what we call evolution. Note that what people call Darwinian
Evolution is just natural selection. I think when we try to say that
natural selection is happening in accord with God, we are merely
supporting theistic evolution (which need not go to the extreme of
what ID suggests).
I don't think you are using the terminology in the same way I
normally hear it applied.
The best definition I have found of microevolution is that of
changes within a species. That is, much like the artificial selection
we do with domesticated animals. Microevolution is, by every
definition I've ever heard, evolution without speciation. That is, if
a bird with a longer beak survives more often than a bird with a
short beak (to use Darwin's example), and so if we have natural
selection of the bird with the longer beak -- within the same
species, mind you! -- then we have had microevolution.
As soon as you have species changes, you start moving into
macroevolution. From my friends at the Oxford American English
Dictionary:
"Microevolution: evolutionary change within a species or small
group of organisms, esp. over a short period."
"Macroevolution: major evolutionary change. The term applies
mainly to the evolution of whole taxonomic groups over long periods
of time."
Personally, neither of these are terribly troubling, I think,
and I'd be inclined to suggest both have/will occurred, albeit to a
much smaller extent than Darwinians would advocate (that is, I think
mutations could negatively cause speciation, but that would only
explain some variation, not the gaining of higher forms from lesser
forms). The troubling issues, I think, go back much further, as I
said before:
1.) Abiogenesis -- life from non-life is very unscientific, but
necessary for a non-intelligent creation of life. Note the
mathematical impossibility of this and the related complexity of DNA
has led life-long atheist, and probably the clearest contemporary
atheist philosopher, Antony Flew, to recently become a theist.
2.) A big bang without cause -- this suggests the big bang
itself is the uncaused cause, which seems to defy what people want to
suggest it is. This is a moot issue, though, since it is, by
definition, impossible to see what caused a big bang, since we cannot
see outside of our reality. But, logic rules the day here: there must
be a cause that was not within the present laws that require
causation... something eternal. Something that is non-contingent,
since something that is contingent must both have had a time that it
didn't exist and a time that it will not exist. Without a non-
contingency, nothing can exist, for nothing existed. A non-contingent
thing is, of course, God. To say it better than I ever could:
"But it is impossible for these always to exist, for that which
is possible not to be at some time is not. Therefore, if everything
is possible not to be, then at one time there could have been nothing
in existence. Now if this were true, even now there would be nothing
in existence, because that which does not exist only begins to exist
by something already existing."
Once you set life in motion at some point, be it 4,004 years ago
or 4.5 byo, I think you will have some evolution, possibly of both
types, but most certainly intraspecies (micro).

Nor does microevolution require such, macroevolution would seem
to, however. But not really. ID proponents would suggest the genetic
material already exists, and is revealed by the processes of
macroevolution.
Just my $0.06 (adjusted for inflation).
