Species identification was carried out by nucleotide sequence analysis of the cytochrome b (cytb) gene. The aim of the study was to identify biological specimens from diverse vertebrate animals by extracting and amplifying DNA from 44 different animal species covering the 5 major vertebrate groups (i.e. mammals, birds, reptiles, amphibians and fishes). The sequences derived were used to identify the biological origin of the samples by aligning to cytb gene sequence entries in nucleotide databases using the program BLAST. All sequences were submitted to the GenBank including new species which were not observed in the databases. The applicability of this method to the forensic field is demonstrated by simulated casework conditions where different types of samples including problematic specimens such as hair, bone samples, bristles and feathers were investigated to identify the species.
