Body concentrates order. It continuously self-repairs. Every five days you get a new stomach lining. You get a new liver every two months. Your skin replaces itself every six weeks. Every year, 98 percent of the atoms of your body are replaced. This non-stop chemical replacement, metabolism, is a sure sign of life.
Lynn MargulisEvolution is no linear family tree, but change in the single multidimensional being that has grown to cover the entire surface of Earth.
Lynn MargulisPoliticians need a better understanding of global ecology. We need to be freed from our species-specific arrogance. No evidence exists that we are chosen, the unique species for which all the others were made. Nor are we the most important one because we are so numerous, powerful and dangerous.
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.
