The color of the cheiridia dictates the proffered hypothesis of racial differentiation. The pheomelanic or eumelanic cheiridia can be derived directly from the primitive agouti colored cheiridia... and either of the saturate patterns can switch to the other.

However, the constancy of tamarin markings on opposite sides of the Amazon suggests that the character transformation in question is not evolutionarily labile, nor have populations with intermediate phenotypes yet been reported from any Amazonian islands.

In view of (1) the diagnosability of golden­ and black­handed tamarins by bold and consistent pelage markings, (2) the existence of correlated divergence in nonpelage characters, and (3) clear indications from phylogenetic analysis that these taxa are not sister taxa, the currently accepted use of

We saw groups of tamarins daily, in both swampy and well­drained primary forest and in roadside secondary growth. In primary forest, tamarins were invariably sighted in the canopy or subcanopy, but we often saw them descend to within a few meters of the ground in roadside secondary growth; occasionally, groups were seen crossing dirt roads on the ground when the gap between trees on either side was too wide to leap. Unlike other primate species at Paracou, tamarins did not noticeably decline in density from 1991 to 1994, probably because they are not locally hunted for meat.</paragraph>
