Symbiotic Planet: A New Look At Evolution by Lynn Margulis

  (out of 5 stars)

Microbiologist Lynn Margulis presents an argument on behalf of symbiogenesis and Gaia Hypothesis in her book Symbiotic Planet. I had high expectations given Margulis's role in the establishment of the origins of mitochondria in cells. I was profoundly disappointed by the muddled, moody, and downright terrible treatment of her field of work found here.

Margulis starts the book with discussion of the nature of symbiosis and her own personal involvement in microbiological research. A few chapters in, it is difficult to determine if Margulis was trying to present a popular science book or an opinionated memoir. Neither was successfully presented.

Throughout the book, the author makes assertions about the nature of biology and symbiosis which are often described with 'my view' or 'in my opinion'. I'm not asking her to claim such hypothesis are indeed proven fact (although, at times, she does make such assertions), but the presentation, which only rarely includes descriptions of how such theories were validated through research, left me questioning whether Margulis had enough coffee on the morning she wrote the passage. Sometimes she just seems to lose interest in her current subject and changes course in mid-paragraph.

One telling moment in the book is when she is discussing Mendel's work. One sentence sums up the lack of professional presentation and effort that seems to have ruled her production of this book:

According to a brilliant unpublished manuscript by an amateur historian of science whose name I can't remember from Nassau Island in the Bahamas, Mendel saw no evidence at all that species change and evolve (20).

Seriously?!? Margulis is a widely-respected professional biologist who has contributed enormously to cutting-edge science, and she's quoting an unnamed amateur unpublished source to support her point? This appeared on page 20, at which point I was already questioning Margulis' ability to argue and present evidence. The rest of the book was not much better.

Highly disappointing treatment of a highly interesting subject by a well-respected key participant in 20th Century biology. I am really very suprised that this book was this bad. Maybe I just caught this read on a bad day (not likely), but I cannot recommend this book to anyone except the rare reader who has a personal interest in Margulis's theories and mindset. Two very generous stars.
