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 living beings, not just animals, but plants and microorganisms, perceive. To survive, an organic being must perceive - it must seek, or at least recognize, food and avoid environmental danger.
Lynn MargulisThe accumulation of genetic mutations were touted to be enough to change one species to anotherโฆ.No. It wasnโt dishonesty. I think it was wish fulfillment and social momentum. Assumptions, made but not verified, were taught as fact.
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 MargulisWe are unconscious of most of our body's processes, thank goodness, because we'd screw it up if we weren't. The human body is so complex, with so many parts...a system which is far more complex than we can fully imagine. The idea that we are consciously care-taking such a large and mysterious system is ludicrous.
Lynn MargulisBody 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.
