But the micro-macro distinction serves an important purpose for creationists,
IDers &c. It enables them to say that they're not opposed to evolution itself but only
to the macro variety, and thus helps to shield them from the charge of being
I know there's been a lot of debate about this among people a lot more
knowledgeable than I in this area, but it seems to me that Darwin had it right in
focussing on "the origin of _species_." _If_ there are "natural kinds" in biology, the
category of species - defined as an isolated breeding population - can make the best
claim to represent such a kind. & the critical question then is not about a vaguely
defined micro-macro distinction but whether or not one evolutionary mechanism or another
- & natural selection in particular - can give rise to new species.
