Abstract

On the basis of studies of botanists and his own on arctic birds, the author suggests a number of refugia where, during glaciation, speciation of mammals took place in geographic isolation. These refugia are reconstructed on the basis of closely related mammalian species, including the most complex case, that of the caribou forms.
