Book review – Life Changing: How Humans Are Altering Life on Earth

7-minute read

Ever since humans appeared on the scene, we have been altering life on Earth. Where once our actions could be considered part of nature’s fabric, our influence has become outsized and our options to exercise it have multiplied. Though the subtitle of Life Changing does not make it explicit, science writer Helen Pilcher focuses on our impact on the genetics and evolution of life around us. A book that stands out for its balanced tone, it managed to surprise me more than once, despite my familiarity with the topics considered.

Book review – Science in Black and White: How Biology and Environment Shape Our Racial Divide

6-minute read

Some time after I reviewed Angela Saini’s book Superior, I was contacted by medical anthropologist and science writer Alondra Oubré, offering me the opportunity to review her new book. The overall aim of Science in Black and White might be the same – the debunking of the biological arguments used to justify racist thinking – but Oubré shows there is more than one approach to get there.

Book review – The Wolf Within: The Astonishing Evolution of the Wolf into Man’s Best Friend

DNA recovered from archaeological remains, so-called ancient DNA, has caused a revolution in our understanding of human evolution (see my review of Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past). In my review of The First Domestication: How Wolves and Humans Coevolved, I wondered what analyses of ancient DNA would reveal about the domestication of dogs from wolves. I have not had to wait long to find out. Geneticist Bryan Sykes here tells that story, and how man’s best friend subsequently radiated into today’s riot of breeds.

Book review – Ancestors in Our Genome: The New Science of Human Evolution

After I read and reviewed Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past, I thought I knew about the changes to the story of human evolution based on studies of DNA. And given that Ancestors in Our Genome was published a few years before that book, I was curious what it could add to what I had been reading so far. As it turns out, a lot. As with my previous review, I should preface this one with the same warning that things are about to get complicated…

Book review – Blueprint: How DNA Makes Us Who We Are

When I opened this book and read its sales pitch (I paraphrase: “What if I told you of a new fortune-telling device that can predict psychological traits – it’s called the DNA revolution!”) I raised my inquisitive but sceptical eyebrow somewhat. Did I just pick up another piece of pop-psychology pulp? Oh boy, was I wrong! Behavioural geneticist Robert Plomin has written an incredibly interesting book with Blueprint, explaining how rapid advances in DNA sequencing technology are opening vast new vistas on the genetics underlying psychology. And is it ever so different, and more complex, than what hyped-up newspaper headlines have tried to sell us so far.
