::not at all, microevolution can only do more of the same, create sub-species like all Darwin's finches, and then natural selection is conservative and not innovative it only select the subspecie fit to a specific environnement, in macroevolution a minute mutation of a homeogene will alter the ontogenese in it's whole creating new specie or even a new genus "in a full-blown and viable state" or end with an extinction , so you have not to search for missing links and the hyatus in the fossil record are no more a problem.
