Book review – Tears for Crocodilia: Evolution, Ecology, and the Disappearance of One of the World’s Most Ancient Animals

7-minute read

Being of the large and toothy kind, crocodiles have a bit of a public relations problem. Fortunately for them, people such as biologist Zach Fitzner fight their corner. For Tears for Crocodilia, he has gone to great lengths to give the reader a well-rounded picture of crocodilians (the name for the order; its living members are divided over three families: alligators & caimans, true crocodiles, and gharials). This ambitious and wide-ranging debut draws on scientific literature to give a primer on their biology, on personal experience working in and travelling to different countries to introduce the main groups, and on interviews with scientists, zookeepers, and conservationists to include a wide range of viewpoints.

Book review – Aesop’s Animals: The Science Behind the Fables

8-minute read

This is the second of a two-part review delving deeper into the world-famous collection of animal tales known as Aesop’s Fables. Having just reviewed a collection of the fables, I here turn to Aesop’s Animals, which looks at the facts behind the fiction.

It is undisputed that stories shape our perception, especially when told to us repeatedly from a young age. We have collectively bestowed human character traits on animals through Aesop’s Fables and other fairytales. Foxes are sly, donkeys are stubborn, and wolves can never be trusted, right? In Aesop’s Animals, zoologist and science writer Jo Wimpenny takes you on a tour through the study of animal behaviour, both in the field and in the laboratory, to show you what these animals are actually like. Reality, it turns out, is not only stranger than fiction, but also far richer and more fascinating.

Book review – Life’s Edge: The Search for What It Means to Be Alive

7-minute read

The word biology derives from the Greek words bíos (βίος in Greek), meaning “life”, and -logía (-λογία in Greek), meaning “branch of study”, and is usually defined as “the study of life”. But what is life? Remarkably, biologists cannot agree on a definition. Everyone can name clear examples of living and non-living things. However, as so often in biology, there is no sharp demarcation between the two. There is a grey area where things are, well, somewhat alive? Lifelike? It is these borderlands between life and non-life that famous science writer and journalist Carl Zimmer explores in Life’s Edge. Instead of providing an answer, this intellectually stimulating and rewarding book will help you understand why it is such a hard question to begin with.

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.
