Sexual dimorphism in primates: Where are we and where do we go from here?

Abstract

There are currently several debates taking place in palaeoanthropological circles in which the issue of sexual dimorphism is crucial. During the 60th Jubilee of the discovery of the TaungAustralopithecus skull, the authors concurred that much of the debate was due to differences in perception concerning dimorphism, and it was suggested that a study session dealing principally with sexual dimorphism in Primates should be organised with a view to determining what, if anything, could be observed in extant primates that might be utilised for determining the existence of dimorphism in fossil species. An advertisement was placed in the Journal of Human Evolution, calling for papers. Response was encouraging, suggesting that there was indeed a need for such a meeting, which was organised to take place late in November in Italy. Seventeen scientists sent abstracts, but due to the rather short notice, several were unable to attend the meeting. Nevertheless, papers were received and read at the meeting which form the basis for this issue of the Journal of Human Evolution. What remains to be done now, is for a second meeting to be organised at which the findings of the first meeting can be extended backwards in time into the fossil record.
