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 – Tracking the Highland Tiger: In Search of Scottish Wildcats

6-minute read

The Scottish wildcat is one of Britain’s most threatened wild mammals. Legend and lore tell of a fierce animal capable of taking down a man if cornered. Once common, only a small remnant population survives in the Highlands of Scotland and now faces the unlikely threat of genetic dilution by hybridisation. Tracking the Highland Tiger sees nature writer Marianne Taylor go in search of this mysterious cat. But it quickly becomes apparent that the book’s title can be interpreted on several levels.

Book review – Kin: How We Came to Know Our Microbe Relatives

The problem with many history books is that they are written long after the facts, sometimes when the original protagonists are no longer alive. Historians or journalists often have no choice but to puzzle together the pieces of their story from eyewitness testimony or archival sources. Kin: How We Came to Know Our Microbe Relatives is a welcome exception to this rule. Written by emeritus microbiology professor John L. Ingraham, currently 94 years young, this book gives an intellectual history of the discipline of microbiology based on over seven decades of first-hand involvement and observation.

Book review – Smilodon: The Iconic Sabertooth

When it comes to Ice Age fame, sabertooth cats are right up there with mammoths. And within the sabertooth cats, the best-known group is the genus Smilodon. Even if you have not heard that name, you will very likely have seen it depicted. Rather than a pop-science book, this edited collection brings together the who-is-who of sabertooth palaeontology to provide a thorough and technical overview of the current state of the field. And if I did not know any better, I would say that the research community has developed an almost unhealthy obsession with this cat’s large canine teeth.

Book review – The Art of Naming

In my review of Kemp’s The Lost Species: Great Expeditions in the Collections of Natural History Museums, I highlighted the importance of naming species and the rich vein of undiscovered species hiding in museum collections around the world. But how does the naming of species work? And what complications can arise? With The Art of Naming, Michael Ohl has written a surprisingly engaging book on the potentially stuffy topic of taxonomical nomenclature that beautifully complements Kemp’s work.

Book review – The First Domestication: How Wolves and Humans Coevolved

The evolution of domestic dogs from wolves is something that has been written about a great deal. Seeing dogs are one of our oldest domesticates and very close to our hearts, there has been an intense interest in this subject. The First Domestication provides a new perspective by turning to a rich vein of knowledge that is often ignored by contemporary Western scientists: traditional stories from tribal and indigenous peoples. If the sound of that makes you roll your eyes – something I am normally much inclined to do – you would be missing out on an incredibly well-written book that deserves your full attention.

Book review – The Lost Species: Great Expeditions in the Collections of Natural History Museums

Planet Earth is home to a staggering number of species. A 2011 article in PloS Biology gave an educated guess of 8.7 million known species of eukaryotes (this is the domain of life to which all multicellular life forms – plants, insects, fungi, mammals etc. – belong, but excludes single-celled life forms such as bacteria). More staggering still is that this probably is only 10-12% of all existing species, with an estimated 86% of terrestrial species and 91% of marine species as of yet undiscovered.

So, scientists describe new species of plants and animals all the time. This much you probably know. What might come as a surprise, however, is that many of these discoveries are not made in the field, but in the massive natural history collections housed in museums around the world. In The Lost Species, Christopher Kemp takes the reader on a tour through the collections to reveal the stories behind some of these discoveries.
