Book review – Contingency and Convergence: Toward a Cosmic Biology of Body and Mind

6-minute read

This is the final of three reviews of MIT Press books in The Vienna Series in Theoretical Biology dealing with convergent evolution, something I consider to be one of evolutionary biology’s most exciting topics. Are evolutionary changes happy accidents, i.e. contingencies? Or is there a law-like repeatability underneath, explaining why some traits evolve time and again, i.e. convergence? Is it even a matter of either-or? And what lessons does this hold for life elsewhere in the universe? Philosopher Russell Powell wrestles with these questions in a manner that is as rigorous as it is intellectually rewarding. Evolutionary biologists will want to give this excellent book a very close read.

Book review – Convergent Evolution on Earth: Lessons for the Search for Extraterrestrial Life

6-minute read

Planet Earth might just as well be called Planet Water. Not only is our planet mostly ocean, life also started out here. Following his 2011 book Convergent Evolution, palaeobiologist George R. McGhee returns to MIT Press and The Vienna Series in Theoretical Biology to expand his examination to oceanic lifeforms, with the tantalising promise of applying the insights gained to astrobiology. I was particularly stoked for this second of a three-part dive into what I consider one of evolutionary biology’s most exciting topics.

Book review – Army Ants: Nature’s Ultimate Social Hunters

6-minute read

If ants give you the heebie-jeebies, you will want to turn away now, for this book review will deal with the ultimate arthropod nightmare: army ants. If, however, insects are your shtick, stick around, because German entomologist Daniel Kronauer has written a phenomenal book on army ant biology that is chock-a-block with jaw-dropping, award-winning photography.

Book review – Desert Navigator: The Journey of an Ant

7-minute read

When we think of animal navigation, the dramatic comes to mind: globe-trotting birds, migrating monarch butterflies, and ocean-crossing whales. But on a smaller scale, navigation is no less vital and no less interesting. Take the humble desert ant. Desert Navigator is the culmination of a lifetime worth of study by German zoologist Rüdiger Wehner and his many collaborators. It is an astonishing and lavishly produced book that distils half a century of experiments into a richly illustrated narrative.

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 – Never Home Alone: From Microbes to Millipedes, Camel Crickets, and Honeybees, the Natural History of Where We Live

The term “wildlife” tends to evoke images of apex predators, cuddly creatures, or flagship species – usually vertebrate, usually mammalian – living outdoors in the wilderness of jungles, plains, or oceans. But what about closer to home? What about in your home? Ecologist Rob Dunn has written a delightful book showing that we live amidst a veritable zoo.
