The genomic diversity of the Arrernte people of Australia or caterpillar people was investigated utilizing 13 autosomal short tandem repeat (STR) markers. Significant departures from Hardy–Weinberg equilibrium were detected at the D18S51, TPOX and CSF1PO loci, which persisted after applying the Bonferroni correction. Gene diversity values oscillate between 0.6302 (CSF1PO) and 0.8731 (D21S11). Observed heterozygosity (Ho) ranges from 0.2632 (D18S51) to 0.8333 (vWA) and is lower than the expected heterozygosity (He) for 12 of the 13 loci analyzed. The genetic relationships of the Arrernte with Middle Eastern, East Asian, South Asian and Indian populations were analyzed by distance‐based methods, including Neighbor‐Joining trees and nonmetric multidimensional scaling. In addition, the genetic contribution of the populations included in the analysis to the Arrernte gene pool was estimated utilizing weighted least square coefficients. Although the Arrernte population exhibits a remarkable level of genetic differentiation, results of the phylogeographic analyses based on autosomal microsatellite data suggest a certain degree of genetic relatedness between the Arrernte tribe of Australia and populations from the Indian subcontinent. In contrast, the STR diversity analyses failed to detect substantial East Asian contribution to the genetic background of the Arrernte group. Am. J. Hum. Biol., 2008. © 2007 Wiley‐Liss, Inc.
