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.
As mentioned previously in my review of Barbara King’s Evolving God, religion is a pervasive phenomenon, and many scholars have put forward explanations how, when, and why it arose. The arguments King put forth did not convince me that religion is anything more than a by-product of our evolution. Apparently, so did Darwin. Though believers often like to point out Darwin was a Christian too, he struggled to reconcile the two and ultimately lost his faith. American psychiatrist E. Fuller Torrey gracefully acknowledges this intellectual heritage and here updates this idea, putting forth the convincing argument that religion arose as a by-product of brain evolution.
What makes us human? Various authors have dished out various reasons in recently published books. From culture to cooking to creativity (see Fuentes’s The Creative Spark I reviewed previously). Caleb Everett, a professor of linguistic anthropology, here makes the point that the invention of numbers, which could be considered another instance of human creativity at work, has been an instrumental tool in allowing humans to transform the world. Without them, quantities exist, but we have only a vague awareness of them.
With his new book, The Creative Spark, Agustín Fuentes, a primatologist and anthropologist currently at the University of Notre Dame in Indiana, boldly puts forth the idea that what makes humans special is creativity. The ability of humans to switch back and forth between considering what is, and dreaming of what might be, and to then put these thoughts into actions (often collaboratively), has brought us a very long way from our primate origins to the tool-wielding, world-shaping force of nature of today. Along the way, Fuentes wants to do away with some of the dominant narratives regarding human evolution today, or rather, he thinks most of them oversimplify things and lead to distortions in our thinking. Instead, he presents a new synthesis that places creativity front and centre stage as being the most important mechanism that helped us overcome challenges.
Based on the book’s title I was expecting a myth-busting pop-science book. There is some of that, but this book is foremost a very thorough and in-depth literature review of decades worth of research on dolphins to give an as dispassionate and impartial analyis as possible of what the science is, or is not, telling us about dolphin intelligence.
