From the reviews: "Experimental analysis of functional adaptations of facial and skull form in nonhuman primates often has implications for human evolution as well. William Hylander (Duke Univ.) has been a major player in this arena since the early 1970s, and this volume is based on a 2005 symposium in his honor. ... Greater intercitation of chapters would have improved this excellent collection of often-complex papers. Summing Up: Recommended. Graduate students, researchers, and faculty." (E. Delson, Choice, Vol. 46 (8), April, 2009)
