NATURE - INBRED ROYALS SHOW TRACES OF NATURAL SELECTION
EXCERPT:
A provocative analysis now suggests that the Habsburg royal family might have evolved under natural selection over three centuries to blunt the worst effects of inbreeding. Evolutionary theory predicts such a 'purging' process, and researchers have documented the effect in animals and plants. But evidence among humans is scant — in part because of the dearth of data on inbred families spanning many generations.
Royal families such as the Habsburgs are an ideal place to look, says Francisco Ceballos, a geneticist at the University of Santiago de Compostela in Spain, who led the research. He and colleague Gonzalo Álvarez used written records to track the marriages, births and deaths of 4,000 individuals across more than 20 generations. “The royal dynasties of Europe are a lab of inbreeding for human populations,” says Ceballos..."
