Macroevolution is a distinction made by Creationists that separates the change of certain characteristics of a species, from the changes that natural selection, mutations, and genetic drift can, given enough time, lead to the creation of new groups of organisms consisting of a single common ancestor and all the descendants of that ancestor (see Clades). Modern biologists do not make a distinction between microevolution and macroevolution, but instead group it under the general theory of Evolution. The rationale for this is that the change of characteristics inside a species is the primary factor in the defination of a species, thus invalidating an absolute description of species, but instead rendering all members in a species to follow a bell curve of differentiation, thus allowing the rise of a new species.
