Abstract

Demonstrating stasis in the fossil record has proven to be problematic with respect to both data collection and analysis. A previous approach is morphometric analysis of lineages sampled temporally and geographically. A hypothesis of stasis is apparently supported if morphological distances between descendent species and ancestral species are no greater than those between geographically distant samples of the descendent species. Evidence presented in this paper conflicts with such interpretations for at least one bivalve lineage, Chione erosa–Chione cancellata, of the late Neogene of tropical America. The direction and magnitude of morphological variance were quantified between two geographically distant groups of C. cancellata from the Recent, and compared to Pleistocene samples of C. cancellata and Pliocene samples of C. erosa. The results indicate that, although the magnitude of intraspecific geographic variation is as great as interspecific temporal variation, the species are morphologically discrete groups. The direction of morphological variance is as important as its magnitude, and interpretations overlooking this point are at best equivocal.
