Lets get it straight, creationists did not invent the terms micro or macro evolution. Any claim that there is no distinction made among scientists regarding micro vs. macro evolution is not accurate as the following definition from a biology textbook easily contradicts that claim. Microevolution —A change in the gene pool of a population over a succession of generations. Macroevolution —Evolutionary change on a grand scale, encompassing the origin of novel designs, evolutionary trends, adaptive radiation, and mass extinction. —Neil A. Campbell Neil A. Campbell, Biology, 3rd Edition,The Benjamin/CummingsPublishing Company, Inc., 1993. p G17-G18. Even famous evolutionist Ernst Mayrs 1988 classic, Toward a New Philosophy of Biology, asks the question, Does Microevolution Explain Macroevolution? Macro evolution was first used by Filipchenko in variebilität und variation in 1927. fell out of favor in the 1940s when macroevolution was used by Goldschmidt to describe his hopeful monster theory, which is almost a type of saltationism. Goldschmidts theory has recently gained some favor among a few evolutionary developmental biologists, who think his theory might not have been totally wrong (a handful of developmental genes control some really important processes) Dobzhansky and Mayr used the term, but it was scarcely heard among evolutionary biologists, at least in the english-speaking world, for many decades. today, when it is used by biologists, it refers to any change at the species level or above, whereas microevolution is used to mean change within a species.
