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.
Sea otters don’t eat algae. And yet, their diet influences the abundance of seaweed. How? Indirectly. Sea otters eating sea urchins (spiky animals in the same class as sea stars) eating kelp has become a textbook example of a trophic cascade, and Serendipity is a first-hand account by ecologist James A. Estes of how this happened. A trophic cascade refers to the indirect effects that ripple through a food web as a result of, for example, a predator consuming its prey. Simultaneously, the book is a searingly open account of how science is done, how ideas change, and how fortuitous events can suddenly send your research programme off in a whole new direction.
DNA recovered from archaeological remains, so-called ancient DNA, has caused a revolution in our understanding of human evolution (see my review of Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past). In my review of The First Domestication: How Wolves and Humans Coevolved, I wondered what analyses of ancient DNA would reveal about the domestication of dogs from wolves. I have not had to wait long to find out. Geneticist Bryan Sykes here tells that story, and how man’s best friend subsequently radiated into today’s riot of breeds.
Sure, I have been lectured about the birds and the bees, and yet I learned an awful lot more about the bees from Thor Hanson’s latest work Buzz: The Nature and Necessity of Bees. Hanson has previously written popular works about feathers and seeds, and in Buzz he turns his attention to bees. Already this book has garnered a lot of positive press and was Book of the Week on BBC Radio 4. Most people associate bees with honey and therefore with the honeybee, Apis mellifera, but Hanson specifically wants to talk about all the other thousands of bee species, many of which are as interesting and as important, even though some of them are diminutive and hardly noticed.
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.
