Lynn Margulis quotes:

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.

To romp along the connected rooftops and fire escapes of Chicago's second city of garages was my young life's passion.

Life on earth is such a good story you cannot afford to miss the beginning... Beneath our superficial differences we are all of us walking communities of bacteria. The world shimmers, a pointillist landscape made of tiny living beings.

All 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.

My work more than didn't fit in. It crossed willy-nilly the boundaries that people had spent their lives building up. It hits some 30 subfields of biology, even geology.

Of course, the plea for respect for nonhuman life goes far beyond the scientific delight of familiarity with our planet mates. The nonhuman forms of life with which we 6,000 million talking, upright apes share this finite planet are directly or indirectly connected to our well-being.

Politicians 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.

Life on earth is more like a verb. It repairs, maintains, re-creates, and outdoes itself.

Natural selection eliminates and maybe maintains, but it doesn't create.

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.

People think the earth is going to die and they have to save it. That's ridiculous. If you rid the earth of flowering plants, people would die, period. But the earth was without flowering plants for almost all of its history.

People say I am against Darwin. That is ridiculous.

All 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.

There is no scientific reason to think that we, even with space travel, are going to survive as a species for ever, certainly not by biting off the hand that feeds us, which is exactly what we are doing.

The urgency to mate persists in all people as in all other mammals because of the evolutionary drive to continue the species, the inborn imperative for genes to reproduce and hormonal differences that evolved over millions of years.

Evolution is no linear family tree, but change in the single multidimensional being that has grown to cover the entire surface of Earth.

People think the earth is going to die and they have to save it. Thats ridiculous. If you rid the earth of flowering plants, people would die, period. But the earth was without flowering plants for almost all of its history.

The accumulation of genetic mutations were touted to be enough to change one species to anotherâ?¦.No. It wasnâ??t dishonesty. I think it was wish fulfillment and social momentum. Assumptions, made but not verified, were taught as fact.

Despite our very recent appearance on the planet, humanity combines arrogance with increasing material demands, even as we become more numerous. Our toughness is a delusion. Have we the intelligence and discipline to vigilantly guard against our tendency to grow without limit?

Although the detail of our sexual energies and their objects and objectives vastly vary, the existence of our sexuality itself is an undeniable truth.

All scientists agree that evolution has occurred - that all life comes from a common ancestry, that there has been extinction, and that new taxa, new biological groups, have arisen. The question is, is natural selection enough to explain evolution? Is it the driver of evolution?

Everybody knows what a caterpillar is, and it doesn't look anything like a butterfly.

All I ask is that we compare human consciousness with spirochete ecology.

Life learned early on to recognize itself.

Natural selection eliminates and maybe maintains, but it doesn't create... Neo-Darwinists say that new species emerge when mutations occur and modify an organism. I was taught over and over again that the accumulation of random mutations led to evolutionary change [which] led to new species. I believed it until I looked for evidence.

New mutations don't create new species; they create offspring that are impaired.

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.

Neo-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.

The fewer species there are and the fewer species we know about, the fewer questions we even know to ask.

The 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?

The 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.

To 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.

To romp along the connected rooftops and fire escapes of Chicagos second city of garages was my young lifes passion.

We 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.

Why does everybody agree that atmospheric oxygen comes from life, but no one speaks about the other gases coming from life?

We are all of us walking communities of bacteria.
