«Highly recommended.
—Malcolm Peaker, Zoology Jottings»

«Grant's writing is accessible, his explanations of complex science easily digestible, and he is full of genuinely amusing stories. If you ever doubted the validity of this iconic example of rapid evolution, Observing Evolution will set you straight.
—Natural History Bookshop»

«For others who simply enjoy a good scientific detective story, this is among the best.
—British Journal of Entomology and Natural History»

«In this engaging book, Grant documents the places he went and the extraordinary people he met, on this quest to understand parts of the peppered moth story that did not quite add up.
—James Mallet, Harvard University, Evolution»

«Highly recommended for all biology students, especially those interested in entomology and evolutionary biology...It's a real treat to read about some of the giants of entomological research.
—Andrew Wakeham-Dawson, Entomologist's Monthly Magazine»

«Provides a rare, unfiltered glimpse into what doing science is actually like....For Grant, the process of becoming an authority on peppered moths was a truly ground-up affair that began unplanned, with nothing more than a question. To begin working with Biston, he needed to step outside of what, at the time, was his well-defined scientific comfort zone of lab-based research....On a fundamental level, this book reveals that there's an art to doing science.
—Richard Gawne, Tufts University, Journal of Experimental Zoology: Molecular and Developmental Evolution»

«Fascinating...Grant's story is both personal and engaging...His book presents a validation of natural selection data plus a critical assessment of speculation over 50 years in a gripping personal science adventure story.
—Stephen J. O'Brien, Journal of Heredity»

«This book chronicles Grant's efforts to wrestle with details of the operation of natural selection in wild populations of widely geographically separated species of the peppered moth....Grant is a good writer and a great storyteller....[He] is clearly devoted to the scientific process, and wide open to his research subjects showing him something completely unexpected.
—The American Biology Teacher»

«Perhaps what is most special about Grant's chronicle is the passion with which he writes about scientific practice. His love of biology shines through, and it is quite contagious.
—History and Philosophy of the Life Sciences»

«[Grant] beautifully describes how science works and what it is like to be a practicing evolutionary scientist. I recommend his book to all readers, but especially to students. I cannot think of another volume that might be as great an inspiration.
