I was taught over and over again that the accumulation of random mutations led to evolutionary change - led to new species. I believed it until I looked for evidence.
Lynn MargulisAlthough 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 MargulisTo romp along the connected rooftops and fire escapes of Chicagos second city of garages was my young lifes passion.
Lynn MargulisThe fewer species there are and the fewer species we know about, the fewer questions we even know to ask.
Lynn MargulisThe idea that we are "stewards of the earth" is another symptom of human arrogance. Imagine yourself with the task of overseeing your body's physical processes. Do you understand the way it works well enough to keep all its systems in operation? Can you make your kidneys function? Can you control the removal of waste? Are you conscious of the blood flow through your arteries, or the fact that you are losing a hundred thousand skin cells a minute?
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.
