GREAT ADAPTATIONS

A Vanderbilt biology professor digs into “unsolved biological mysteries and extreme adaptations.”

What do star-nose moles, electric eels, jewel wasps, tentacled snakes, and water shrews have in common? The rapt gaze of Catania, who investigates those odd creatures and more. The author knows better than most that even animals that have been studied for centuries harbor secrets yet to be uncovered. Using a variety of visual aids to good effect, Catania explores how the humblest species may have developed their remarkable abilities. The author wants us to learn something not only about these extraordinary creatures, but about the process of discovery as well. This begins, prosaically, with the simple act of taking a closer look. A Guggenheim and MacArthur fellow, Catania was motivated to write the book, in part, as an alternative to the necessarily dry technical style of scientific papers, which by their very nature do little to capture the sense of wonder or elation attending new discoveries. It’s clear that being a scientist has only magnified the author’s sense of wonder, and he notes how chance, failure, an open mind, and tirelessly methodical experimentation are as much natural parts of science as breakthroughs. Very occasionally, he has hit the mother lode in the field, when preparation and a bit of luck intersect with biology, history, and culture, as in the marvel that is earthworm “grunting.” His studies also deal with the larger question of the extremes to which evolution can tailor a species to its environment as well as some potentially profound applications: For example, the venom of the jewel wasp, a leading figure in neuroparasitology, “may be useful for research into Parkinson’s disease.” Perhaps not everyone will share the author’s abundant enthusiasm for the specifics of insectivore senses, amphibian electroreceptors, and the vagaries of neuroanatomy, but his delight is contagious.

Catania successfully unearths a universe of surprises within a small-scale realm.
