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

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

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.

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.

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.

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.

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