Book review – A Polar Affair: Antarctica’s Forgotten Hero and the Secret Love Lives of Penguins

7-minute read

This has to be a story worthy of the name “scoop of the century”. Penguin biologist Lloyd Spencer Davis has been studying mating behaviour in Adelie penguins since 1977, carefully documenting how penguins are far from the paragons of monogamy that they were long held to be. That is until 2012 when an unpublished manuscript comes to light showing that somebody beat him to the punch… by more than six decades! A certain George Murray Levick carefully documented the same penguin antics that Davis would later build his career on. But who was this Levick? And why did he never publish his observations? Join Davis for a most unlikely story of polar exploration, penguins, and perversion.

Book review – The Invertebrate Tree of Life

6-minute read

To outsiders, phylogenetics, the study of the evolutionary relationships between organisms, must seem like quicksand: the landscape is ever-changing and what you thought was solid ground can turn into contested and unstable territory overnight. Even so, we are getting an ever-clearer picture. In no small part this is due to new methods: the rapid technological progress in DNA sequencing has now made it both feasible and affordable to sequence whole genomes (all of a cell’s DNA) instead of selected genes for many taxa. And when you can bring multiple lines of evidence – morphological, developmental, genetic, and palaeontological – to bear on the question of evolutionary relationships, the resulting family trees become better supported and more credible. That is exactly what Gonzalo Giribet and Gregory Edgecombe, both experts in invertebrate biology and palaeontology, have done here in The Invertebrate Tree of Life – a work of dizzying scope since 96% of all known species are invertebrates. They have synthesized a truly monstrous amount of research to give an overview of our current thinking on invertebrate phylogeny, writing a new benchmark reference work for students of invertebrates.

Book review – Dance of the Dung Beetles: Their Role in Our Changing World

6-minute read

Having just reviewed The Mosquito, I am continuing the theme of small things running the world. Here is another overlooked insect that literally moves mountains, doing the dirty job that nobody wants to do: the dung beetle. Entomologist Marcus Byrne has teamed up with popular science writer Helen Lunn for Dance of the Dung Beetles, a captivating and charming introduction to their cultural history, their role in the history of biology as a discipline, and some really funky contemporary research.

Book review – Superlative: The Biology of Extremes

5-minute read

Extremes fascinate us: the biggest, the fastest, the oldest, the tallest. Books and TV-programmes regularly scratch our itch for records, whether it is feats of engineering or biological extremes, and many sporting events revolve around humans attempting to set new records. One glance at the cover of Matthew D. LaPlante’s book Superlative and you might think that this is yet another book offering lots of gee-whiz factoids. You would also be wrong. Instead, this is an amusing and fascinating book that digs just that much deeper into the biology behind extremes, and why studying them is so worthwhile.

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 – Fires of Life: Endothermy in Birds and Mammals

6-minute read

Endothermy, colloquially known as warm-bloodedness, was a major breakthrough in the history of life on Earth. It gave rise to the active lifestyle of birds and mammals. But how did it evolve? Research into this question has been ongoing for decades, though in the eyes of evolutionary physiologist Barry Gordon Lovegrove, the field has stagnated amidst competing single-cause hypotheses that all try to find that one killer explanation. In his wide-ranging Fires of Life, he brings together many disparate strands of research and gives an overview of our thinking on the evolution of endothermy in mammals and birds. Providing food for thought for students in this field, it also is a great overview for the general reader that stands out for its superbly accessible writing.

Book review – Malthus: The Life and Legacies of an Untimely Prophet

6-minute read

Thomas Robert Malthus, a man so praised and vilified that his name has been immortalised in the noun “Malthusianism”. Many people will have heard of him in the context of overpopulation, but how many of you know the title of his famous book? Robert J. Mayhew is a Professor of Historical Geography and Intellectual History and with Malthus: The Life and Legacies of an Untimely Prophet he makes the case that Malthus’s book is a good example of the unread classic. Deeply researched, this is a scholarly book for the patient reader that charts Malthus’s life and, especially, his intellectual legacy. As Mayhew shows, Malthus remains as relevant as ever, though he continues to be misinterpreted in manifold ways.

Book review – The Dark Side of the Hive: The Evolution of the Imperfect Honeybee

The honey bee has a very positive reputation: a clever, industrious insect that organises itself in remarkably collaborative societies. But bee researchers Robin Moritz and Robin Crewe want to balance this picture. Yes, bee colonies are a marvel, but once you stop focusing on the level of the colony, all sorts of imperfections become apparent: cheating, robberies, regicide, euthanasia, evolutionary maladaptations, illogical reproductive strategies, etc. Welcome to the dark side of the hive.

Book review – Mama’s Last Hug: Animal Emotions and What They Teach Us about Ourselves

Do animals experience joy, grief, or shame? Most people will be quick to attribute all sorts of emotions to pets and other animals. But many biologists remain uncomfortable with this, well, touchy-feely subject. As scientists, we are trained to be objective, cool, and detached when making observations. Anthropomorphism – the attribution of human traits to animals – has traditionally been a big no-no. But the tide is turning, and well-known Dutch-American primatologist Frans de Waal is here to help it along. Mama’s Last Hug is a smart, opinionated, and insightful book arguing we have long overestimated humans and underestimated animals.

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.
