This is an engaging pop sci look at the evolution of morphologies and behaviors that influence conflict in animals. Why can animals display such starting traits of aggression? Why do some species have such stunning features like the teeth of sharks, the tusks of an elephant, or the elaborate, varied horns of beatles? These features seem to often defy logic. Sucking an exceptional amount of precious energy from the animal, conflict and the ornamentations associated with it (defensive and offensive) seem to evolve in some species to absurd extremes that shorten an animal’s life span.
Emlen explains how such traits and behaviors evolve, and why. The simple answer for the latter is what drives evolution of any characteristic. Those with the genes to produce the characteristic have better reproductive success – of passing on those genes to the next generation.
Chapter by chapter Emlen describes particular cases observed in animals where evolution of defensive or offensive traits is evident. Tying these to a human metaphor of war and technology, Emlen draws parallels between what is seen in biology and what is seen in human history in terms of weapon and armor development.
In terms of the science I am a little disappointed in the focus on animals alone. The weapon metaphor could certainly extend through all of life, with more interesting and varied examples. Moreover, the evolution of battle long predates animals; he really is only covering a tiny recent set of biological developments in this realm. But Emlen’s expertise is in animals and that is the group of organisms that everyone is most familiar with, so okay.
I did appreciate the basic history of human developments in battle that Emlen used to compare with the biological examples. The battle metaphor begins to stretch a little though with the close of the book which begins to postulate on how the future of human developments in weapons could lead to unavoidable catastrophe. This is certainly true. I am not convinced that biological systems of evolution are good proof of this however. Biological evolution is not the same as the ‘evolution’ of technology. The selection for weapon-like traits or battle-related behaviors in animals is not the same as in human war. While it makes for a catchy close to the book, it isn’t accurate or particularly meaningful, beyond a play on emotions.
Though I feel there are some issues with this book in taking very precise scientific concepts and trying to popularize them to a general audience, for the most part I think Emlen does well and would recommend this to anyone with an interest in biology or nature.

The Case of the Vanishing Little Brown Bats: A Scientific Mystery,
by Sandra Markle
Publisher: Millbrook Press
48 pages, Hardcover
Published: 1st Sep. 2014
With bat decorations just around the corner for Halloween, now is a perfect time to check out this wonderful nonfiction science book with any curious young scientists in your life.
The Case of the Vanishing Little Brown Bats is about the recent fungal infections (white-nose syndrome) that has decimated brown bat populations in North America.
As a biologist and bat lover myself, I appreciated the way that Markle told this scientific story of epidemiology in an engaging way that can introduce children to diverse concepts: the wonders of nature, the effects of the microbial world on larger familiar organisms, the process of scientific investigation, the power of curiosity and creativity, and the importance and benefit of research.
Markle relates these rather complex ideas with straightforward language that is ideal for a middle school (or even late elementary) aged child, all in the format of a ‘scientific mystery’: the observation that something is wrong with bats and the steps that were taken to try and discover what was causing the problem. Only then, with dedicated research and understanding can the problem be addressed, a mystery must be solved.
Apparently this book is part of an entire series, so I’ll have to look into the other titles offered. Although I could only look at this on a Kindle, the photos and illustrations are plentiful, bright, and well-done. I should note that given the topic of a deadly disease of bats, there are illustrations that may be considered ‘gross’ or ‘uncomfortable’. I appreciate the honesty that the text and photos show in just how awfully devastating disease can be for any organism and the price that must be paid to try and determine its cause and treat it. I also really appreciated the realistic images of scientists just simply doing their work in the lab, the latest equipment at hand.
This book is really a great opportunity to expose a child to the wonder of nature and the appeal of science. It makes complex, and perhaps even frightening realities accessible to children and may help inspire curiosity or dreams in a future scientific researcher.

Wandering HOme: A Long Walk Across America’s Most Hopeful Landscape, by Bill McKibben
Publisher: St. Martin’s Griffin

Published: 1st April 2014

In this inspirational essay that blends nature appreciation, travel, and environmental activism, Bill McKibben structures his ruminations around a walking journey he undertook from his present-day home in Vermont as professor at Middlebury College to his former home across the lake in the New York Adirondacks.
Wandering is an apt word to describe the essay, for it is not primarily about details of the actual journey, nor is it particularly about the natural features of the two neighboring regions. While both of these topics are given voice, the walking trek and its environment are really just a narrative backdrop to symbolically contain McKibben’s wandering thoughts and anecdotes. These anecdotes primarily take the form of recounted encounters with other people along McKibben’s route who embody a sort of spirit or cause that he meditates upon, as in the style of a sermon.
Personally I would have enjoyed this more if there had been greater structure to it, if there had been fuller details on the journey and the environment, or a deeper probing of the ecological, social, and political themes that the anecdotes touch upon. However, I acknowledge that isn’t what this work is meant to be, and the brief read that this essay provides is certainly inspirational. Thus, for those who do appreciate this kind of book and have a striking love of nature or environmental activism, you will enjoy it.
While I found Wandering Home to be too cursory overall, I certainly did also find moments of intense beauty and inspiration within it. McKibben’s writing is impassioned and poetic. The passages where he is detailing the environmental qualities of each region are evocative and rich. The meditative quality of the text and its wandering nature probably make this the type of book that isn’t best read in one sitting as I did, or even in the same span of general time. This is more like a resource that could be dipped into during precious reflective times, or a during a moment’s anticipation of going on a similar hike or journey.
If nothing else, Wandering Home serves as a fine, gentle reminder that other types of existence – closer to nature – are possible than the one we may be accustomed with, and perhaps we could each find ways to seek and embrace some aspect of these alternatives.
