An interview with NASA's Astrobiology Magazine, Part 2:

"Microcosmos: Four Billion Years of Microbial Evolution (Amazon UK | US), co-authored by Lynn Margulis and her son Dorion Sagan, was first published twenty years ago. Astrobiology Magazine recently interviewed Margulis, to find out how her and Sagan's ideas have stood the test of time. In this, the second part of a four-part interview, she talks about four specific microbial organisms that, through fusion, yielded modern plant and animal cells.

From Lynn Margulis' homepage:

She argues that inherited variation, significant in evolution, does not come mainly from random mutations. Rather new tissues, organs, and even new species evolve primarily through the long-lasting intimacy of strangers. The fusion of genomes in symbioses followed by natural selection, she suggests, leads to increasingly complex levels of individuality. Dr. Margulis is also acknowledged for her contribution to James E. Lovelock's Gaia concept. Gaia theory posits that the Earth's surface interactions among living beings sediment, air, and water have created a vast self-regulating system.

James Lovelock has recently written "The Revenge of Gaia: Earth's Climate Crisis and the Fate of Humanity" (Currently appearing on the 'Featured Books' page of the Evolution Book Store: UK | US - or go directly to the Amazon book webpage: UK | US - see "The End of Eden: Gaia and James Lovelock"
