The seed of this book, if you will forgive me the pun, lay in an unfortunate collision between a football and the author’s scrotum. This led former neurobiologist Liam Drew to write a piece for Slate about the mammalian testicles and their precarious positioning in the males of this group. Before long, with the birth of his first daughter, he started wondering about lactation and all the other features and oddities that make us mammals. The resulting I, Mammal is a witty, irreverent overview of mammalian biology and evolution that is sure to entertain.
Not so long ago, the idea that giant reptiles once roamed the earth was novel, unbelievable to some, but their reign represents only one part of deep time. Go back further in time, to the Carboniferous (358.9 to 298.9 million years ago), and you will find a world of giants as bizarre and otherworldly as the dinosaurs must have once seemed to us. A world where clubmoss trees grew up to 50 metres tall, with scorpions as large as dogs and flying insects the size of seagulls. With Carboniferous Giants and Mass Extinction, palaeobiologist George McGhee, Jr. presents a scholarly but fascinating overview of the rise and fall of this lost world, and why it still matters to us.
When you think of an animal, you will most likely think of a vertebrate. Since we are animals with a backbone ourselves, it is not strange that that which is closest to us comes to mind first. But when and how did vertebrates evolve? To answer that question, Nature editor Henry Gee takes a good hard look at invertebrates, convincing the reader that they are not all equal. More than 20 years ago, Gee wrote Before the Backbone: Views on the Origin of the Vertebrates, which took a look at historical explanations for the origins of vertebrates. Which group of invertebrates is closest to us remains a topic of active research and Across the Bridge brings readers up to date with our current thinking.
Starting your book blurb by asking why gazelles have legs rather than wheels is a suitably out-there question to immediately grab a reader’s attention. A more pertinent question then; why is all life based on carbon rather than silicon? In The Equations of Life, Charles Cockell takes the reader on a giddy tour down the organisational hierarchy of life – from sociobiology to subatomic particles – to show that nature is far more predictable and understandable than it might appear at first blush. His eloquent answer to above and other why questions? “Because physics is life’s silent commander”.
Cephalopods, the group of molluscs that include the octopus, squid, cuttlefish and nautilus, are some of the most fascinating invertebrates to live in the world’s seas. Especially the octopus is famed for its intelligence and mind-bending acrobatics, being able to squeeze through the smallest hole. There have been some fantastic popular books on cephalopods recently, from William’s entertaining Kraken: The Curious, Exciting, and Slightly Disturbing Science of Squid to several works focusing on the octopus (Godfrey-Smith’s Other Minds: The Octopus and the Evolution of Intelligent Life, Montgomery’s touching The Soul of an Octopus: A Surprising Exploration of One of the World’s Most Intriguing Creatures, which made me tear up in more than one place, Mather et al.‘s Octopus: The Ocean’s Intelligent Invertebrate, and Harmon Courage’s Octopus! The Most Mysterious Creature in the Sea). But, as marine biologist Danna Staaf remarks, what’s been missing is a popular book on the evolution of cephalopods. Having been fascinated with them since childhood, she eventually decided to write Squid Empire. All hail the squid!
Convergent evolution is a thing of beauty. Whether it is wings in bats, birds and pterosaurs, or eyes in a range of organisms, evolution often seems to come up with functionally similar solutions to life’s challenges. So how predictable is evolution? This is a question that has fascinated generations of biologists and, as Losos quickly makes clear, two famous figures loom large.
