DNA is found in the cells of all living organisms and it provides a blueprint of their history over different time frames.  We can use DNA signatures to investigate relatedness between family members, within populations, and how populations are connected to each other.  At higher levels we can use DNA to identify species and how these species are related to other organisms.  Project Manta is a part of the Molecular Fisheries Laboratory at UQ and employs DNA methods to investigate several of these questions, with particular focus on population size and structure.
