Book review – Extended Heredity: A New Understanding of Inheritance and Evolution

In my recent review of She Has Her Mother’s Laugh: The Powers, Perversions, and Potential of Heredity, I mentioned how the concept of heredity has become ever fuzzier the more we have learnt about how traits can be passed to the next generation. We have come from a very gene-centric period in biology, but biologists Russell Bonduriansky and Troy Day are ready to shake up the field. Neither a Lamarckian redux nor an attempt to downplay the importance of genes, this book successfully argues that the time has come to take into account non-genetic forms of heredity. Along the way, they provide a very interesting history lesson on how we got here in the first place.

Book review – The Book of Humans: The Story of How We Became Us

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.

Book review – The Creative Spark: How Imagination Made Humans Exceptional

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.
