MUSEUM THERIOLOGICAL COLLECTIONS FOR THE STUDY OF GENETIC DIVERSITY

Molecular methods to analyse DNA variability are opening new perspectives in the role played by museums in biodiversity research. DNA can be extracted from specific tissue collections, as well as from traditional voucher specimens. Ancient and museum DNA research produce valuable information for defining the phylogenetic positions of extinct taxa, the reconstruction of molecular and organismal evolution or extinct species, the characterization of extinct populations, including animal diets or microbial infections. Historical DNA samples are important sources of information also for conservation and evolutionary studies. In this paper, the methods used for ancient DNA anlaysis and the main results reported in published studies are reviewed.
