Recent radiation in West African Taterillus (Rodentia, Gerbillinae): A concerted role of chromosome and climatic changes

A comparison of the seven specific karyotypes of genus Taterillus and a cladistic analysis performed using chromosomal rearrangements character states are discussed. It was hypothesized that the process underpinning cladogenesis involved highly under dominant genomic rearrangements that were fixed fully pronounced populational bottlenecks from a drastic climate and subsequent environmental changes.
