This volume takes its subtitle from the theme of the ASHB meeting for 1996 "Human Adaptibility: Future Trends and Lessons from the Past". The first paper is the annual conference lecture `Human Evolution Today: Which Way Next?' delivered by Professor Maciej Hennenberg, the newly appointed Wood Jones Professor at the University of Adelaide. This is followed by the transcripts of two papers resulting from a debate on `Species and Human Evolution,' also from the meeting. The first is `Species Concept in Palaeoanthropology' by Colin Groves and the second, `The Problem of Species in Hominid Evolution' by Maciej Hennenberg.There are also a series of individual papers. Two of these are shorter integrative pieces: `Philosophical Problems in Palaeoanthropology' by Darren Curnoe, and `A Biological Basis for Generative Learning in Science' by Lynette Schavieren and Mark Cosgrove.These are followed in turn by two proffered papers on specific problems: `Patterns of Morphological Discrimination in the Human Talus: a Consideration of the Case for Negative Function', by Robert Kidd and Charles Oxnard, and `The Specific Status of a new Siwalik Sivapithecine Specimen' by David Cameron, Rajeev Patnaik and Michelle Stevens.The final contribution is one of the longer integrative papers which has characterised each of the prior volumes: `The Interface of Function, Genes, Development and Evolution: Insights from Primate Morphometrics' by Charles Oxnard.
