Lynn Margulis Quotes
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.

The Pope went on to state that Evolution was consistent with Roman Catholic doctrine, changing a position that had been taken by the Catholic Church and many fundamental protestant denominations. A few actually still reject evolution even after all the evidence and proof of the basic Darwinian theses. There is nothing in evolution that per se denies the existence of God or even that God created the universe and the mechanism of evolution. That is why the Catholic Church and so many Protestant Churches, Judaism, Buddhists, and so many other religions have no theological problem with evolution. Those religious groups who have difficulty with evolution are those fundamentalists (Protestants, Jewish and Muslims) who believe in the literal truth of Holy Scripture. They also assume that God designed each particular plant or animal species. Other religions hold that it was God who created the mechanism of evolution and that is how all the species developed and are developing today. Some religious evolutionists believe that evolution is God’s mechanism for perfecting man.
Evolution sometimes produce or retain components that have no purpose or are even inefficient. But he is urging the biologist to remember that none of the life form were designed much less designed efficiently. We humans have an appendix for example, which does nothing positive and sometimes gets infected and kills us. Yet it is still there. We have so much else on the positive side that a few weaknesses are not material to our survival.
Lynn Margulis was an American evolutionary theorist, biologist, science author, educator, and science popularizer, and was the primary modern proponent for the significance of symbiosis in evolution. Historian Jan Sapp has said that "Lynn Margulis's name is as synonymous with symbiosis as Charles Darwin's is with evolution." In particular, Margulis transformed and fundamentally framed current understanding of the evolution of cells with nuclei – an event Ernst Mayr called "perhaps the most important and dramatic event in the history of life" – by proposing it to have been the result of symbiotic mergers of bacteria. Margulis was also the co-developer of the Gaia hypothesis with the British chemist James Lovelock, proposing that the Earth functions as a single self-regulating system, and was the principal defender and promulgator of the five kingdom classification of Robert Whittaker.
