'''Macroevolution''' is the theory that [[natural selection]] can, given enough time, lead to the creation of new [[clade]]s which are groups of organisms consisting of a single common ancestor and all the descendants of that ancestor. Macroevolution also requires a large number of beneficial mutations. The scientific data regarding mutations causing the changes necessary for macroevolution has been seen by some as damaging to the macroevolutionary position. <ref>http://www.trueorigin.org/mutations01.asp</ref>
