The discovery of the presumably lost grave of the controversial English king Richard III in Leicester (U.K.) was one of the most important archaeological achievements of the last decennium. The skeleton was identified beyond reasonable doubt, mainly by the match of mitochondrial DNA to that of living maternal relatives, along with the specific archaeological context. Since the genetic genealogical analysis only involved the DNA sequences of a single 15th century individual and a few reference persons, biologists might consider this investigation a mere curiosity. This mini-review shows that the unique context of a historical king's DNA also has relevance for biological research per se — in addition to the more obvious historical, societal and educational value. In the first place, the historical identification appeared to be a renewed forensic case realising a conservative statement with statistical power based on genetic and non-genetic data, including discordant elements. Secondly, the observation of historical non-paternity events within Richard III's patrilineage has given rise to new research questions about potential factors influencing the extra-pair paternity rate in humans and the importance of biological relatedness for the legal recognition of a child in the past. Thirdly, the identification of a named and dated skeleton with the known historical context serves as a reference for bioarchaeological investigations and studies on the spatio-temporal distribution of particular genetic variance. Finally, the Richard III case revealed privacy issues for living relatives which appear to be inherent to any publication of genetic genealogical data.

The image represents a simplified ‘open’ cell of the gram-positive bacterium Streptomyces coelicolor and selected components of its zinc metabolism. The zinc sensor protein – zinc uptake regulator (Zur) – is shown in metallic blue in the middle, bound to DNA (green) where it works as a transcriptional repressor when zinc levels are adequate. The Zur-regulated high-affinity zinc uptake system ZnuABC is shown in purple. Synthesis of the secreted zincophore coelibactin is also Zur-regulated. Zinc ions are shown as silver balls surrounding the cell, and bound to Zur; for details see pages 983–1001.
The image has been created by Alevtina Mikhaylina with the help of Claudia A. Blindauer and David J. Scanlan.
