The degree to which historical human activities negatively impacted past and present lemur species is a long-standing question in primatology. At present, most evidence addressing this issue comes from archaeology, paleontology, and behavioral studies. Genetic data provide another source of evidence. In this study, six microsatellite loci, genotyped on more than 360 wild Verreaux's sifaka, are used in order to test the hypothesis that this population experienced a population bottleneck in the last 2000 years. Excess heterozygosity is compared with the heterozygosity expected under mutation-drift equilibrium in order to test for the genetic signature of a rapid population contraction in the past. The results indicate that the sifaka population did not experience a population bottleneck. Various methodological and conceptual implications of this result are discussed.
