Book review – On the Origin of Evolution: Tracing ‘Darwin’s Dangerous Idea’ from Aristotle to DNA

8-minute read

History will forever associate Charles Darwin with the theory of evolution, but the idea was in the air. Had not Darwin published his famous book, someone else would have likely snatched the prize. Husband-and-wife duo John and Mary Gribbin here examine the wider milieu in which Darwin operated and the many thinkers who preceded him. Given their previous collaborations, the first two parts of On the Origin of Evolution read like a well-oiled machine, but the book falters when they turn their eyes to the legacy of Darwin’s ideas.

Book review – The Story of Evolution in 25 Discoveries: The Evidence and the People Who Found It

6-minute read

After three previous books in this format on fossils, rocks, and dinosaurs, geologist and palaeontologist Donald R. Prothero here tackles the story of evolution in 25 notable discoveries. More so than the previous trio, this book tries to be a servant to two masters, resulting in a mixed bag.

Book review – Some Assembly Required: Decoding Four Billion Years of Life, from Ancient Fossils to DNA

7-minute read

The history of life is punctuated by major transitions and inventions: fish that moved onto land, reptiles that turned into birds. But how did these happen? In Some Assembly Required, Professor of Organismal Biology and Anatomy Neil Shubin provides an up-to-date and utterly engrossing account of the latest thinking on the great transformations in evolution. And he has one clue for you: nothing ever begins when you think it does…

Book review – The Selfish Ape: Human Nature and Our Path to Extinction

6-minute read

Having just read Barash’s Through a Glass Brightly, it seemed logical to next read The Selfish Ape by biologist Nicholas P. Money. With the dustjacket calling the human being Homo narcissus, and the book “a refreshing response to common fantasies about the ascent of humanity“, these two clearly explore the same ideas, though one look at the cover suggests a darker tone. Money mostly takes the reader on a tour of human biology to show how we are little different from our fellow creatures, spicing up his writing with bleak observations. This one, my friend, sees through the glass darkly…

Book review – Good Enough: The Tolerance for Mediocrity in Nature and Society

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.

Book review – Biology’s First Law: The Tendency for Diversity & Complexity to Increase in Evolutionary Systems

The subtitle of this book points to an observation that most biologists will anecdotally agree with. Looking at the long sweep of evolutionary history, there is indeed a clear overall tendency for life forms to become more diverse and complex. Daniel W. McShea and Robert N. Brandon, the one a biologist with a secondary appointment in philosophy, the other a philosopher with a secondary appointment in biology, here declare it the Zero-Force Evolutionary Law or ZFEL. But is this a law of nature? And does it really differ from stochastic processes or even entropy?

Book review – Life Finds a Way: What Evolution Teaches Us About Creativity

Back in 2014, evolutionary biologist Andreas Wagner blew my mind. His book Arrival of the Fittest: Solving Evolution’s Greatest Puzzle gave fascinating answers to the question of where evolutionary innovations come from. I will say more about it below, but in short, there are many ways to solve a problem. But, as Life Finds a Way shows, not all solutions are equally good. To evolve from a suboptimal solution to a superior one usually involves several steps through intermediary solutions that are even worse, something that natural selection acts against. So how does evolution overcome such obstacles? And what does the answer have to do with human creativity? Can we apply these ideas further afield in education or economics? And is this book going to be as good as his last one? So many questions…

Book review – Discovering Retroviruses: Beacons in the Biosphere

In the already unusual world of viruses, retroviruses stand out for being even more so. Called “retro” because they reverse the flow of genetic information from RNA to DNA, rather than the normal DNA to RNA, they have turned out to be ancient, omnipresent, and incredibly influential. They are also important as they cause diseases such as AIDS. With Discovering Retroviruses, Anna Marie Skalka delivers a book dedicated to this particular group that is as technical as it is fascinating.

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.
