Why are we, from an evolutionary standpoint, the last man standing? This question fascinates archaeologists and anthropologists, and the dominant narrative is one of humans outcompeting other hominin lineages, driving them extinct. In the process, our evolutionary cousins, such as Neanderthals, always get the short end of the stick, being clumsier, dumber, or just generally inferior to us. In a book that is both a popular summary of his work and a critique of current thinking in archaeology, evolutionary biologist Clive Finlayson aims to redress this balance. Neanderthals, he says, were a lot smarter than we give them credit for, and one unexpected line of evidence comes from the birds that lived alongside them.
Having just read Barash’s Through a Glass Brightly: Using Science to See Our Species as We Really Are, 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…
Most people will at least be mildly familiar with the story of how the structure of DNA was discovered. Francis Crick and James D. Watson are household names in this story as they went on to win a Nobel Prize. But can you name the third person to share it with them? Most people will also have heard of Rosalind Franklin, but as Gareth Williams shows, so many other people were relevant to this story. Watson and Crick only put the finishing cherry on the cake. Unravelling the Double Helix covers the preceding 85 years of breakthroughs, blind alleys, near-misses, and “beautifully executed bellyflops” by some of the greatest scientists of their time.
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.
Many works of popular science claim to be histories of almost everything or everyone, but earth scientist Robert M. Hazen might actually be in the position to stake that claim. Whether you are talking stellar evolution, the origin of life, organic chemistry, synthetic materials, or hydrocarbon fuels – the multifaceted atom carbon is ubiquitous and pervasive. Symphony in C is a whirlwind tour through geology, biochemistry, and evolutionary biology that is an incredibly absorbing read, although in places it almost comes apart at the seams under the intensity of its enthusiasm.
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?
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…
Over something as mundane as the tone of one’s skin humans have been inflicting intense grief and misery upon each other for centuries. And when biology and anthropology arose as scientific disciplines, they were brought into the fold to justify subjugation, exploitation, and slavery. With Superior: The Return of Race Science, journalist Angela Saini has written a combative and readable critique of race science that seems to be rearing its ugly head again. But in her fervour, does she take it too far to the other extreme?
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.
Beware the virus. If there is one message physician and evolutionary biologist Frank Ryan is hammering home with this book, it is this. Viruses are absolutely everywhere and more numerous even than microbes. So much so that Ryan speaks of the virosphere rather than the biosphere. But more than harbingers of disease, they are also agents of evolutionary invention. Now why does that sound familiar?
