So why is the creationist version of widespread speciation due to heritable variance and natural selection called microevolution? It seems to me the terms are reversed.
for the wide variety of different critters we now have to all come from one microscopic bug over half a billion years, slowly and sensibly, strikes me as the micro category. For them all to spring from the small number of livestock (7 pairs each) and vermin (2 pairs) that could be represented on a 3-story wooden boat, in less than 5000 years, would seriously be macroevolution.
