Abstract: | During an anthropological survey in the South-West of Irian Jaya (Indonesian New Guinea), 145 blood samples were collected
from the coastal Asmat population. ABO, MNSs, Rh, Kell, Duffy and Kidd red cell antigen systems were investigated and the
results are presented here. ABO, MNSs, Rh gene frequencies of the Asmat, together with those of 21 other New Guinea populations,
were examined by principal component analysis. The topological representation of the distribution of the selected New Guinea
populations confirms high variability in the interior of the island, and possible causes are discussed. A hypothesis is advanced,
concordant with language evidence which would explain the resemblance among populations from opposite coasts of New Guinea
and between some mountain and coastal groups. When the comparison includes 32 other world populations, the New Guinea groups
constitute one assemblage distinct from the others. |
