On November 22nd, 2011 Lynn Margulis died. Last week Carl Woese died. In their deaths, we lost two of the most radical visionaries of a generations, of several generations really. Last week I posted an updated section from my book, Every Living Thing, about the work of Woese. This week I’ve uploaded the companion story about Lynn Margulis. Though they disagreed with each other, the fates of these two researchers and the truths they revealed were, in many ways, linked. 

The only real valuable thing is intuition.—”Einstein

When I was an undergraduate, two theories were held up for ridicule, to show how farfetched scientific theories can get. One was the theory of continental drift and the other was the symbiotic theory of the origin of the cell.” –William Culberson, professor of Botany at Duke University.
