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 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 MargulisThe notion of saving the planet has nothing to do with intellectual honesty or science. The fact is that the planet was here long before us and will be here long after us. The planet is running fine. What people are talking about is saving themselves and saving their middle-class lifestyles and saving their cash flow.
