Glossary.

"But few current volumes offer the flexibility inherent in the
sheer comprehensiveness of The Emergence of Humans. In this
remarkably compact volume, Ash and Robinson, both of whom teach at
the U.K.'s Open University, cover (in varying depth) virtually
everything that a focused course in this subject might want to
address, while avoiding related areas of anthropology." (The
Quarterly Review of Biology, 1 March 2011)

"The Emergence of Humans is an accessible, informative
introduction to the scientific study of human evolution. . .
written by two authors with a wealth of teaching experience The
Emergence of Humans will prove invaluable to students in the
biological and natural sciences needing a clear, balanced
introduction to the study of human evolution. Recommendation:
would make a good undergraduate level textbook." (The Birdbooker
Report, 16 November 2010)
