Population history at the microscale: craniometrics of Cayo Santiago macaques
Metadata[+] Show full item record
Being able to understand the effects of relatedness on adult cranial morphology has implications for inferring population histories, and for informing us about the influence of genetics on cranial form among human populations. Several methods have been developed to infer relatedness among human or other primate populations using metric data. R-matrix methods have typically been used to approach questions of population history on global or regional scales with a time depth of tens to thousands of generations. This study uses detailed genealogical and demographic information for rhesus macaques born over four decades on Cayo Santiago along with individually matched cranial measurements.
