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
