Unfortunately,mitochondrial DNA has been opted for in systematic and phylogenetic research . Unfortunately, however, the preserved vertebrates in natural history museums do not have allied tissue samples for DNA study since they were collected prior to the molecular revolution in systematic biology, and also collectors during those periods did not opt to preserve tissue samples parallel to preserved voucher specimens
(2,3). Molecular systematists were thus left with the option of trying to recover usable DNA from the preserved specimens, particularly for evolutionary studies. Th e ability to extract, amplify, and sequence DNA from various preserved specimens has opened the possibility of using museum specimens to address questions pertaining to molecular evolution and genetic understanding of various species(4).
