Summary: Variation in quantitative dermatoglyphics among three endogamous groups of marine fishermen of Puri Coast, India, is greater for the palmar variables than for the fingers. This is the case in both the sexes. The pattem of population affinities, however, differs for the males and females. In order to evaluate the importance of palmar variables in population studies, the results in males are compared with those of finger variables and anthropometrics. There is no significant heterogeneity between the groups for finger variables. Although significant inter­group variability is observed in the palmar and anthropometric traits, the two sets of results are not in the same direction. Palmar dermatoglyphic relationships reflect the caste affiliations, while the anthropometric are in line with geographic proximity.

Introduction

In an earlier paper (Reddy et al. 1 986) we have examined biological affinities between the three endogamous groups of fishermen of Puri coast, lndia, using a set of anthropometric and dermatoglyphic variables each. The results based on the an­thropometric measurements suggested closer similarity between sympatric popula­tions rather than ethnically similar ones. The dermatoglyphic traits, however, did not provide a clear picture regarding ethnic or geographic affiliations. Disagreement in the pattern of population affinities, based on anthropometrics and dermatoglyphics, has been observed in many earlier studies (Chai 1 972 ; Neel et al. 1 974 ; Friedlaender 1 97 5 ; Rudan 1 97 8 ; j antz & Chopra 1 98 3 ) . This is generally interpreted as a result of the different roles of evolutionary and/or environmental factors causing variation
