A Search for Human Origins is of interest to all primatologists, whether they study living or extinct species. ... A Search for Human Origins deals with paleontological collecting in different parts of the world, principally in Egypt, but also in Libya, Tanzania, India, China, and North America. ... a testament to the enduring influence of Elwyn Simons on vertebrate paleontology, primate evolution, and prosimian biology and conservation. (Susan Cachel, International Journal Primatology, Vol. 29, 2008)
Elwyn Simons: A Search for Origins, edited by John Fleagle and Chris Gilbert, succeeds primarily because no real attempt at blanket coverage of Elwyn's career is made. Instead, it is a delightfully idiosyncratic sampling of personal history, fossil discovery, and comparative study. ... This book includes coverage of subfossil lemurs and the current status of Malagasy ecosystems, current finds in North Africa, India, and Asia and even a chapter on hominid behavioral ecology, all of which reflect the interests and passions of Elwyn Simons.
