Deep time is one of the most mind-boggling yet underappreciated concepts to come out of the disciplines of evolutionary biology and the earth sciences. As an editor with Nature for over three decades, Henry Gee has had a front-row seat to numerous exciting scientific developments that have enriched our understanding of Earth’s vast 4.6-billion-year history. This high-octane popular science book is his take on the genre of the “earth biography”.
Given that we are nothing but mammals, it is perhaps understandable that humans are rather mammal-centric, something that conservation organisations capitalise on. But where palaeontology is concerned, dinosaurs get all the love. And that does early mammals little justice says Scottish palaeontologist and Palaeocast co-host Elsa Panciroli. Far from mere bit players cowering in the shadows of these “terrible lizards”, mammals have a long and rich evolutionary history that predates the dinosaurs but is poorly known outside of specialist circles. Panciroli’s debut changes all that and does so in a most readable and immersive fashion.
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.
