Quaternary beetle research: the state of the art

Quaternary beetle research has progressed in a variety of ways during the last decade. New kinds of data are being extracted from the fossil specimens themselves, such as ancient DNA and stable isotopes. The ancient DNA studies hold the promise of proving new insights on the stability of beetle genotypes. The study of stable isotopes of H and O from fossil beetle chitin holds the promise of providing an independent proxy for the reconstruction of temperature and precipitation. The discipline is also expanding into previously unstudied regions, such as Australia, New Zealand, and northern Asia. Along with the new study regions, new schools of thought are also forming in the discipline, challenging old research paradigms. This is a necessary step forward for the discipline, as it grows and develops in the 21st Century.
