摘要：

Two new chromosome races of the common shrew Sorex araneus Linnaeus, 1758 have been discovered in Eastern Siberia (Strelka and Ilga). This finding helps to clarify the geographical limits of other previously-described chromosome races (Tomsk and Baikal) in the same region and to elucidate the chromosome evolution of Siberian common shrews. The diversity of chromosome races in this area can be explained by stepwise accumulation of Robertsonian fusions and whole-arm reciprocal translocations from a Baikal-like ancestral race.
