Abstract
Experiments using the immunological technique of micro-complement fixation indicate that chipmunks diverged from the tree squirrel lineage during the Oligocene. Three chipmunk lineages (Tamias, Eutamias: Neotamias, and Eutamias: Eutamias) have been distinct since the late Miocene. Fossil, morphological, karyotypic, and other immunological data are discussed and shown to agree with our conclusions on relationships of these three lineages.This publication has 2 references indexed in Scilit:
