As we all know, Russian entomologist Yuri Filipchenko coined the terms, and not so Creationsists could use them to obfuscate evolutionary theory, but to differentiate them. Opposition to the terms by scientists is based more on the fact that they *are* in fact, differing functions.

Microevolution is observable, macro- is not. The failure of drosophila to be anything but, after ~100 years, has been disapointing. But Mayr and Doby coined terms for reproductive isolation, categorizing them as speciation, and in effect, moving the goal posts.

Talk Reason's 29+ essay uses not only outright microEv examples, but allopatric, sympatric, parapatric and hybrid models, where gamette incompatability has arisen do NOT verify speciation (except by the relaxed standards). True speciation requires much more. Co opted homologies in some cases, but clearly, genetic engineering in others.

"Not naming the designer neatly provides deniability to the proposition that his is a religious idea ... "
Designers of bioforms could be other incarnates, angelics (surogates), an intelligent mechanism other than NS, front loading, or tinkering by savant idiots. Even if a supreme being was responsible, it would not constitute the furtherance of an ordained religion, which was Jefferson's intent to prevent. Moreover, even if the concept of theistic evolution has any relevancy, its investigation would in no way lead to the teaching of religion, or worse, a theocracy.

" ... and, of course, if aliens are responsible, then the idea answers nothing (where did they come from?)"
Would you agree there's room in the cosmos for other intelligences? Or is our little grain of sand the only possible domain in the cosmic arena? And by 'alien', I assume you mean biologic life forms. Is all life DNA based? If so, there could be no travel between galaxies, or even neighboring stars, a huge waste of real estate.
