Carl Simpson has authored a review of The Evolution of Multicellularity in Trends in Ecology & Evolution:

What features do all multicellular organisms share due to the common evolutionary problems and what differences are due to the constraints imposed by their unicellular ancestors? That is no easy task; not least because the answers to those questions span all biological disciplines. 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).
