SYMBIOTIC PLANET

A NEW LOOK AT EVOLUTION

Let’s hear it for the bugs— not your creepy-crawlies, but bacteria, the be-all (and possible end-all) of life on Earth, according to Margulis. Here she describes the once radical theory that cells have incorporated bacteria to mutual advantage and uses that as a springboard to summarize a still more radical theory of how species evolve. She calls it serial endosymbiosis theory (SET). It is now conventional wisdom that the energy-producing mitochondria in animal cells were once free-living bacteria. Indeed, they have their own genes—different from nuclear DNA. Margulis provides many examples of fruitful symbioses, including sexual union itself as the merger of sperm and egg cells. According to SET, there are successive steps or mergers that led to multicellular life forms: In steps one and two the oldest bacterial forms—the non-oxygen breathing “archaebacteria” found in deep ocean vents—merged with swimming bacteria two billion years ago to form the nuclear heart of animal, plant, and fungal cells and provide the cilia for swimming. Later steps introduced a third partner able to breathe oxygen and added the ability to engulf and digest food (phagocytosis). The last step involved engulfing yet another bacterium—but one these various new forms of life could not digest: bright green photosynthetic bacteria. The bone of contention here is the origin of ciliated cells—critical to evolution for their vital role as sperm tails, among other things. Margulis has a theory about their origin, but as they say, more research is needed. Margulis’s theory also dictates a change in taxonomy to five kingdoms: bacteria at the base, then “protoctists” (algae, slime molds, ciliates) next, and then animals, plants, and fungi. Finally, she defends Lovelock’s Gaia theory, which she interprets to mean that enormous interacting ecosystems on Earth achieve homeostasis rather than that the planet is in the hands of some benign Mother Earth. This is vintage Margulis—personal, autobiographical, passionate, argumentative, at times over the top, but full of ideas—at least some of which, in the past, have proved to be right.

WHY FISH DON'T EXIST

A STORY OF LOSS, LOVE, AND THE HIDDEN ORDER OF LIFE

A quirky wonder of a book.

A Peabody Award–winning NPR science reporter chronicles the life of a turn-of-the-century scientist and how her quest led to significant revelations about the meaning of order, chaos, and her own existence.

Miller began doing research on David Starr Jordan (1851-1931) to understand how he had managed to carry on after the 1906 San Francisco earthquake destroyed his work. A taxonomist who is credited with discovering “a full fifth of fish known to man in his day,” Jordan had amassed an unparalleled collection of ichthyological specimens. Gathering up all the fish he could save, Jordan sewed the nameplates that had been on the destroyed jars directly onto the fish. His perseverance intrigued the author, who also discusses the struggles she underwent after her affair with a woman ended a heterosexual relationship. Born into an upstate New York farm family, Jordan attended Cornell and then became an itinerant scholar and field researcher until he landed at Indiana University, where his first ichthyological collection was destroyed by lightning. In between this catastrophe and others involving family members’ deaths, he reconstructed his collection. Later, he was appointed as the founding president of Stanford, where he evolved into a Machiavellian figure who trampled on colleagues and sang the praises of eugenics. Miller concludes that Jordan displayed the characteristics of someone who relied on “positive illusions” to rebound from disaster and that his stand on eugenics came from a belief in “a divine hierarchy from bacteria to humans that point[ed]…toward better.” Considering recent research that negates biological hierarchies, the author then suggests that Jordan’s beloved taxonomic category—fish—does not exist. Part biography, part science report, and part meditation on how the chaos that caused Miller’s existential misery could also bring self-acceptance and a loving wife, this unique book is an ingenious celebration of diversity and the mysterious order that underlies all existence.

A quirky wonder of a book.

Italian theoretical physicist Rovelli (General Relativity: The Most Beautiful of Theories, 2015, etc.) shares his thoughts on the broader scientific and philosophical implications of the great revolution that has taken place over the past century.

These seven lessons, which first appeared as articles in the Sunday supplement of the Italian newspaper Sole 24 Ore, are addressed to readers with little knowledge of physics. In less than 100 pages, the author, who teaches physics in both France and the United States, cogently covers the great accomplishments of the past and the open questions still baffling physicists today. In the first lesson, he focuses on Einstein's theory of general relativity. He describes Einstein's recognition that gravity "is not diffused through space [but] is that space itself" as "a stroke of pure genius." In the second lesson, Rovelli deals with the puzzling features of quantum physics that challenge our picture of reality. In the remaining sections, the author introduces the constant fluctuations of atoms, the granular nature of space, and more. "It is hardly surprising that there are more things in heaven and earth, dear reader, than have been dreamed of in our philosophy—or in our physics,” he writes. Rovelli also discusses the issues raised in loop quantum gravity, a theory that he co-developed. These issues lead to his extraordinary claim that the passage of time is not fundamental but rather derived from the granular nature of space. The author suggests that there have been two separate pathways throughout human history: mythology and the accumulation of knowledge through observation. He believes that scientists today share the same curiosity about nature exhibited by early man.

An intriguing meditation on the nature of the universe and our attempts to understand it that should appeal to both scientists and general readers.
