'In How the Snake Lost its Legs, Professor Held describes the key concepts that are at the foundation of evo/devo, in a language that is clear and simple as well as scientifically accurate, and in a manner that is sure to captivate the curious reader. In the second half of the book, he unveils a series of 'Just So' stories, a mixture of fascinating vignettes providing insights into what we now know about the evolution of various creatures, and teasing explorations of what remains to be learned. The book is a wonderful introduction to the field.' Cliff Tabin, Harvard Medical School
'Professor Held has created a remarkable work of scholarship, notable for its accessibility, readability, and breadth with an overall welcoming tone that is reminiscent of those memorable professors who make the complex approachable through their lectures … The book works on several levels, suitable for sampling as well as for an entire read. The concluding 'bestiary' celebrates the diversity of life and the vast array of questions that await answers. Students in particular will benefit from the book's presentation of multiple examples of the changing face of knowledge, how a story can be woven from a careful reading and cross-comparison of the literature, and the power of generating organization schemes (classifications) to help make sense of a complicated body of literature.' Richard L. Blanton, North Carolina State University
'Lewis Held has explicitly not written a 'textbook' - it is much more informal and whimsical than that. He has succeeded admirably in exploring evo-devo through a format akin to Kipling's Just So Stories (there is a fine irony here). He ranges from thoroughly researched topics … through to intriguing snippets … A wealth of information and ideas is conveyed with rigour, clarity and wit, and the text is supported by excellent, distinctive figures and by generous reference to the research literature. This remarkable book is a real 'page-turner' and it is likely to both inform and enchant all of us interested in biological diversity and how it arises.' Vernon French, University of Edinburgh
'No single research study can convey what Lewis Held's new book does: demonstrate the richness of evolutionary developmental biology as a way to understand major transitions in evolution and their mechanistic underpinnings. This is a must-have resource for anyone who is teaching or learning or simply interested in evolutionary biology.' Günter P. Wagner, Yale University
'… accessible to any reader interested in evolutionary biology while also satisfying the more expert 'evo-devotees' willing to explore the depicted topics in depth.' Arnaud Martin, Evolution and Development
Taking inspiration from Kipling's 'Just So Stories', this book explores emerging insights from evo-devo to explain the science behind tiger stripes, camel humps, and many other fascinating animal traits. Held's unique and engaging style makes this narrative both enlightening and entertaining, guiding students and researchers through even complex concepts.
