Depending upon the condition of the sample, mitochondrial and/or nuclear DNA may be extracted and DNA sequence obtained from samples such as degraded faunal and floral remains, teeth, bones, tissue, hair, artifacts and archival specimens.
The DNA sequence obtained from PCR-derived DNA templates may assist in such things as:
Verification of Identity
Identification of Rare or Unidentified Species
Historical Reconstructions
Establishment of Origins and Relationships of Species
Evolutionary Biology Studies
