Although random mutations influenced the course of evolution, their influence was mainly by loss, alteration, and refinement... Never, however, did that one mutation make a wing, a fruit, a woody stem, or a claw appear. Mutations, in summary, tend to induce sickness, death, or deficiencies. No evidence in the vast literature of heredity changes shows unambiguous evidence that random mutation itself, even with geographical isolation of populations, leads to speciation.
Lynn MargulisAll of us from fertile egg to embryo to corpse, are exactly that: warm, wet, furry animals compelled by the sexuality of our forefathers and foremothers to be, either directly or indirectly, our own exciting and excitable, provocative and provocable selves.
Lynn MargulisTo me, the human move to take responsibility for the living Earth is laughable - the rhetoric of the powerless. The planet takes care of us, not we of it. Our self-inflated moral imperative to guide a wayward Earth, or heal our sick planet, is evidence of our immense capacity for self delusion. Rather, we need to protect ourselves from ourselves.
