The Universe Within

October 8, 2012
University of Chicago paleontologist Shubin wrote about the fishy origins of humanity in 2009’s Your Inner Fish. In his new book, he goes farther back and further out, explaining how humans bear the markings of cosmic phenomena; as he puts it, “Written inside us is the birth of the stars.” Here, the author surveys everything from glints in “Greenlandic rocks” to the spreading signs of supernovae to reveal “deep ties to the forces that shaped our bodies.” He demonstrates how mammals owe their “high-energy lifestyle” to oxygen released hundreds of millions of years ago as continents spread apart, and how color vision arose after continental drift cooled the planet, diversified flora, and resulted in biological competition that favored those organisms who could identify nutritious plants according to hue (“Every time you admire a richly colorful view, you can thank India for slamming into Asia”). Shubin is a leading proponent of the fusion of paleontology, developmental genetics, and genomics, and the result of his efforts is a volume of truly inspired science writing. Appropriately vast in scope, Shubin deftly balances breadth and depth in his search for a “sublimely beautiful truth.” Photos & illus.

In a follow-up to Your Inner Fish: A Journey into the 3.5-Billion-Year History of the Human Body (2008), Shubin (Biological Sciences/Univ. of Chicago) delivers an equally engrossing history of life's connections to everything else. The author begins with the most common element in the human body, hydrogen, which also makes up 90 percent of the universe. All hydrogen existed along with helium and a trace of lithium when everything began 13.7 billion years ago. Heavier elements were made later inside stars, some of which end their lives violently. Cosmic dust that condensed to form the sun 5 billion years ago also made the planets. Microorganisms appeared soon after the Earth cooled enough to support liquid water--so soon that many scientists believe that life is not a rare accident, but inevitable under the right circumstances. Shubin recounts the subsequent 4 billion years of changes in both life and its surroundings. Oxygen, absent at first, slowly accumulated as photosynthetic plants multiplied. The Earth's rocky crust shifted, eroded and cracked, leaking volcanic gases from the interior. Continents formed and split, expanding and shrinking the oceans; the resulting mountains, shifting ocean currents and migrating landmasses carried life across the planet, forcing it to adapt to the changing environment or nearly wiping it out. The sun is 30 percent hotter than when life began; in another billion years, it will make the Earth too warm to support life. An intelligent, eloquent account of our relations with the inanimate universe.

A University of Chicago paleontologist and evolutionary biologist, Shubin discovered the fossilized Tiktaalik roseae ("a mosaic of primitive fish and derived amphibian"); his best-selling Your Inner Fish parallels human anatomy with the structures of the fish that first wriggled landward. Here he goes one step further, explaining how the universe's 14-billion-year history is reflected in our very bodies. With a 100,000-copy first printing and a ten-city tour.

Walt Whitman yawped, I contain multitudes, and in Your Inner Fish (2008), Shubin confirmed him by demonstrating how the evolution of life on earth is inscribed in the human body. Now Shubin shows that all creation, from the big bang on, is packed in there, too. Hard to swallow? Well, ingestion had little to do with it. But analogize rocks and bodies, both of which bear the signature of the great events that shaped them. Shubin relates the discoveries of eight such events and their signatures. The big bang gave us the atoms of our bodies. The formation of the solar system, by allowing earth so much water, helped determine our size, shape, and functionality. The big whack that gouged the moon out of the earth established the rhythms of everything from days and months to each person's sleep cycle and cell division. The manufacture of oxygen by single-celled creatures licensed the growth of bigger ones, such as ourselves, and also their aging. Plate tectonics set the limits of our habitation, from the womb to the Tibetan plateau. Catastrophes besides the moon-gouging shaped our innate adaptability. The global carbon cycle that enabled the ice ages colored our vision. Climate change molded our genes. In short, universal history made us what we are.
