THE STORY OF EARTH

THE FIRST 4.5 BILLION YEARS, FROM STARDUST TO LIVING PLANET

Hazen (Earth Science/George Mason Univ.; Genesis: The Scientific Quest for Life's Origins, 2005, etc.) offers startling evidence that “Earth's living and nonliving spheres” have co-evolved over the past 4 billion years.

To support his persuasive though controversial views, the author updates evidence collected by mineralogists over the last two centuries. Describing the “discoveries of organisms in places long considered inhospitable [to life] – in superheated volcanic vents, acidic pools, Arctic ice and stratospheric dust,” he argues for the dating of the origin of life more than a billion years earlier than estimates based on Nobel Prize winner Harold Urey's groundbreaking experiments. These appeared to support the view that life originated 2.5 billion years ago in an oceanic environment with the creation of organic molecules. Hazen explains how Urey and his associates were able to re-create “primordial soup” in a simulation, which produced “a suite of biomolecules stunningly similar to what life actually uses.” That theory has been challenged in the last two decades, based on the discovery that life “fueled by chemical [rather than solar] energy” exists in extreme environments in astonishing abundance. Hazen and colleagues at the Carnegie Institution’s Geophysical Laboratory (with support from NASA) have succeeded in simulating conditions that would have existed on Earth as early as 4.5 billion years ago, while producing biomolecules that are today the building blocks of life. The author situates this latest experimental evidence in a series of discoveries about the earth's geological evolution, sparked by analysis of moon rocks brought back by Apollo astronauts.

A report of a fascinating new theory on the Earth's origins written in a sparkling style with many personal touches.

THE GENIUS OF BIRDS

Science writer Ackerman (Ah-Choo!: The Uncommon Life of Your Common Cold, 2010, etc.) looks at the new science surrounding avian intelligence.

The takeaway: calling someone a birdbrain is a compliment. And in any event, as Ackerman observes early on, “intelligence is a slippery concept, even in our own species, tricky to define and tricky to measure.” Is a bird that uses a rock to break open a clamshell the mental equivalent of a tool-using primate? Perhaps that’s the wrong question, for birds are so unlike humans that “it’s difficult for us to fully appreciate their mental capabilities,” given that they’re really just small, feathered dinosaurs who inhabit a wholly different world from our once-arboreal and now terrestrial one. Crows and other corvids have gotten all the good publicity related to bird intelligence in recent years, but Ackerman, who does allow that some birds are brighter than others, points favorably to the much-despised pigeon as an animal that “can remember hundreds of different objects for long periods of time, discriminate between different painting styles, and figure out where it’s going, even when displaced from familiar territory by hundreds of miles.” Not bad for a critter best known for bespattering statues in public parks. Ackerman travels far afield to places such as Barbados and New Caledonia to study such matters as memory, communication, and decision-making, the last largely based on visual cues—though, as she notes, birds also draw ably on other senses, including smell, which in turn opens up insight onto “a weird evolutionary paradox that scientists have puzzled over for more than a decade”—a matter of the geometry of, yes, the bird brain.

Ackerman writes with a light but assured touch, her prose rich in fact but economical in delivering it. Fans of birds in all their diversity will want to read this one.

Loads of good explaining, with reminders, time and again, of how much remains unknown, neatly putting the death of science...

A SHORT HISTORY OF NEARLY EVERYTHING

Bryson (I'm a Stranger Here Myself, 1999, etc.), a man who knows how to track down an explanation and make it confess, asks the hard questions of science—e.g., how did things get to be the way they are?—and, when possible, provides answers.

As he once went about making English intelligible, Bryson now attempts the same with the great moments of science, both the ideas themselves and their genesis, to resounding success. Piqued by his own ignorance on these matters, he’s egged on even more so by the people who’ve figured out—or think they’ve figured out—such things as what is in the center of the Earth. So he goes exploring, in the library and in company with scientists at work today, to get a grip on a range of topics from subatomic particles to cosmology. The aim is to deliver reports on these subjects in terms anyone can understand, and for the most part, it works. The most difficult is the nonintuitive material—time as part of space, say, or proteins inventing themselves spontaneously, without direction—and the quantum leaps unusual minds have made: as J.B.S. Haldane once put it, “The universe is not only queerer than we suppose; it is queerer than we can suppose.” Mostly, though, Bryson renders clear the evolution of continental drift, atomic structure, singularity, the extinction of the dinosaur, and a mighty host of other subjects in self-contained chapters that can be taken at a bite, rather than read wholesale. He delivers the human-interest angle on the scientists, and he keeps the reader laughing and willing to forge ahead, even over their heads: the human body, for instance, harboring enough energy “to explode with the force of thirty very large hydrogen bombs, assuming you knew how to liberate it and really wished to make a point.”

Loads of good explaining, with reminders, time and again, of how much remains unknown, neatly putting the death of science into perspective.
