Changes

'''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 significant changes necessary for macroevolution is extremely damaging to the macroevolutionary position.<ref>http://www.answersingenesis.org/home/area/faq/mutations.asp</ref> <ref>http://www.trueorigin.org/mutations01.asp</ref>

In spite of these apparent hurdles, scientists have been able to document a case in which species have undergone significant behavioral and biological adaptations in very short time periods (less than 40 years).<ref>http://news.nationalgeographic.com/news/2008/04/080421-lizard-evolution.html</ref>
