== Little Consensus Regarding an Evolutionary Process ==
There is little consensus among scientists about how macroevolution is said to have happened as can be seen below:

"“The history of organic life is undemonstrable; we cannot prove a whole lot in evolutionary biology, and our findings will always be hypothesis. There is one true evolutionary history of life, and whether we will actually ever know it is not likely. Most importantly, we have to think about questioning underlying assumptions, whether we are dealing with molecules or anything else.” - Jeffrey H. Schwartz, Professor of Biological Anthropology, University of Pittsburgh, February 9, 2007 <ref>http://www.uncommondescent.com/darwinism/there-is-no-theory-of-evolution/</ref><ref>http://mac10.umc.pitt.edu/m/FMPro?-db=ma&-lay=a&-format=d.html&id=2807&-Find</ref>

"There have, of course, been dissenting voices, arguing for a plethora of processes in addition to neo-Darwinian mechanisms. These include species selection and the importance of contingent events, notably mass extinctions. Some of these arguments are laced with a rhetorical exegesis, and notably have paid little attention to molecular insights." - Simon Conway Morris (palaeontologist, Department of Earth Sciences, [[University of Cambridge|Cambridge University]], UK), "Evolution: Bringing Molecules into the Fold," Cell, Vol. 100, pp.1-11, January 7, 2000, p.11 <ref>http://members.iinet.net.au/~sejones/mechns01.html</ref><ref>[http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6WSN-4195FC1-1&_user=681891&_coverDate=01%2F07%2F2000&_rdoc=1&_fmt=&_orig=search&_sort=d&view=c&_acct=C000037419&_version=1&_urlVersion=0&_userid=681891&md5=1806889a6d57f9282db2e4c04d32e8f7]</ref>

"If it is true that an influx of doubt and uncertainty actually marks periods of healthy growth in a science, then evolutionary biology is flourishing today as it seldom has flourished in the past. For biologists collectively are less agreed upon the details of evolutionary mechanics than they were a scant decade ago. Superficially, it seems as if we know less about evolution than we did in 1959, the centennial year of Darwin's on the Origin of Species." - [[Niles Eldredge]], "Time Frames: The Rethinking of Darwinian Evolution and the [[Theory of Punctuated Equilibrium|Theory of Punctuated Equilibria]]," Simon & Schuster: New York NY, 1985, p.14 <ref>http://members.iinet.net.au/~sejones/mechns01.html</ref>
