1st Edition
The Evolution of Multicellularity
Among the most important innovations in the history of life is the transition from single-celled organisms to more complex, multicellular organisms. Multicellularity has evolved repeatedly across the tree of life, resulting in the evolution of new kinds of organisms that collectively constitute a significant portion of Earth’s biodiversity and have transformed the biosphere. This volume examines the origins and subsequent evolution of multicellularity, reviewing the types of multicellular groups that exist, their evolutionary relationships, the processes that led to their evolution, and the conceptual frameworks in which their evolution is understood. This important volume is intended to serve as a jumping-off point, stimulating further research by summarizing the topics that students and researchers of the evolution of multicellularity should be familiar with, and highlighting future research directions for the field.

Biography
Matthew D. Herron is a Senior Research Scientist in the School of Biology at the Georgia Institute of Technology. He received his PhD from the University of Arizona and held postdoctoral positions at the University of British Columbia, the NASA Astrobiology Institute, and the University of Montana. He has authored or co-authored dozens of peer reviewed scientific papers.
William C. Ratcliff is an Associate Professor in School of Biological Sciences at the Georgia Institute of Technology, where he co-directs the Interdisciplinary Graduate Program in Quantitative Biosciences. He received his PhD from the University of Minnesota. At Tech, he leads a research group that examines the evolution of multicellularity through directed evolution, synthetic biology, and mathematical modeling.
Peter L. Conlin is a Postdoctoral Researcher in the School of Biological Sciences at the Georgia Institute of Technology. He received his PhD from the University of Washington. He has authored or co-authored several peer reviewed scientific papers.
The emergence of multicellular organisms is one of the most striking transitions in evolution. This nicely illustrated volume covers this topic from many angles, with 18 chapters by outstanding researchers in this fascinating and productive field. – Richard Lenski, Michigan State University
No major transition was more major than that from single-celled to multicellular life. The editors of and contributors to The Evolution of Multicellularity do a wonderful job walking the reader through that transition. I heartily recommend this book to (multicellular) readers everywhere. – Lee Dugatkin, University of Louisville
The new volume, The Evolution of Multicellularity edited by M.D. Herron et al., pulls together current thought on multicellularity from workers across a constellation of fields. This volume does a wonderful job covering the issues: from how to recognize multicellularity (Chapter 2), multilevel selection (Chapter 3), to multicellularity in fungi (Chapter 14), algae, and plants (Chapters 15 and 16). – Carl Simpson, Trends in Ecology & Evolution
