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. 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. [1]
