In popular discourse, the theory of evolution has become a victim of its own success, reduced to sound-bites such as “survival of the fittest”. Biologists will of course quickly point out that this is an oversimplification, though philosopher Daniel S. Milo takes things a few steps further. Good Enough is a thought-provoking critique of the dominance of adaptationist explanations. He argues that, while natural selection is important, it is not the only, possibly not even the default mechanism, in evolution. No, Milo claims, the mediocre also survive and thrive.
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.
Humans. How is it that you can herd 200 of them into an aeroplane without a riot erupting, while they also commit unspeakable atrocities such as torture, genocide, and war? Anthropologist Richard Wrangham calls it the goodness paradox. In this well-reasoned book, he surveys research from a range of disciplines to try and answer why humans show this odd combination of intense calm in normal social interactions and a ready willingness to kill under certain other circumstances.
So, quick question for you. What is life?
Sorry, that’s a trick question, for the answer to this is anything but quick. The mind-boggling complexity that is life, even something as “simple” as a bacterium, somehow arises from atoms and molecules. And yet, physics and chemistry as we currently know it seem incapable of answering how life’s complexity emerges from its constituent parts. With The Demon in the Machine, well-known physicist and cosmologist Paul Davies takes a stab at it, saying we are on the verge of a breakthrough.
Historically, humans have long considered themselves special compared to the natural world around them. It shows, for example, in old depictions where humans are at or near the top of a chain of lifeforms, with only angels and gods above us. Darwin caused a tremendous ruckus by saying we were descended from primates, and evolutionary biology has since had a long history of diminishing our anthropocentric worldview. With The Book of Humans, self-professed science geek Adam Rutherford has written an entertaining exploration of human evolution, showing that, amidst the teeming multitudes of lifeforms surrounding us, we are really not that special. And yet we are.
If Charles Darwin were to walk into my office today and ask me: “So, what did I miss?” I think I would sit the good man down with a copy of She Has Her Mother’s Laugh, telling him: “Here, this should get you up to speed”. Darwin struggled to explain how traits were being inherited from generation to generation. As New York Times columnist Carl Zimmer shows in this wide-ranging book, the story of heredity has turned out to be both diverse and wonderful, but has also been misappropriated to prop up some horrible ideologies.
Do you have a dog? I grew up surrounded by Newfoundlanders. Ever wondered what they are thinking? Whether they think at all? You’d be forgiven for thinking that What It’s Like to Be a Dog is another book for dog lovers and, in part, it is. But don’t let the title mislead you, this book is primarily a popular account of ongoing developments in animal neuroscience, specifically on what scanning mammal brains using magnetic resonance imaging (MRI) can tell us about our shared similarities.
