||P.4725 right column 2nd paragraph:"In an attempt to document a correlation between sample age and DNA preservation, [researchers] use a quantitative real-time PCR (qPCR) design to measure relative copy
numbers of mitochondrial DNA (mtDNA) fragments from bones of the extinct New Zealand moa (Aves: Dinornithiformes)."
||Abstract:"The average DNA half-life within this geographically constrained fossil assemblage was estimated to be
521 years for a 242 bp mtDNA sequence, corresponding to a per nucleotide fragmentation rate (k) of
5.5×10^–6 per year."
