All scientists agree that evolution has occurred-that all life comes from a common ancestry, that there has been extinction, and that new taxa, new biological groups, have arisen. The question is, is natural selection enough to explain evolution? Is it the driver of evolution?
Lynn MargulisNeo-Darwinian language and conceptual structure itself ensures scientific failure: Major questions posed by zoologists cannot be answered from inside the neo-Darwinian straitjacket. Such questions include, for example, 'How do new structures arise in evolution?' 'Why, given so much environmental change, is stasis so prevalent in evolution as seen in the fossil record?' 'How did one group of organisms or set of macromolecules evolve from another?' The importance of these questions is not at issue; it is just that neo-Darwinians, restricted by their resuppositions, cannot answer them.
