Macroevolution is the theory that natural selection can, given enough time, lead to the creation of new clades which are groups of organisms consisting of a single common ancestor and all the descendants of that ancestor. This process requires that the genetic material of an organism must be added to. One method this could be produced by is the "duplication and divergance", of genes [1]. Macroevolution also requires a large number of beneficial mutations. Creationists claim that scientific data regarding mutations causing the significant changes necessary for macroevolution is extremely damaging to the macroevolutionary position. [1][2]
