英文の中のwhereについて教えてください。
Despite Galton's finding of high inherited ability in scientists, a standard biographical study of great mathematicians, Men of Mathematics by the mathematician Eric Temple Bell, first published in 1937, shows just how little inherited mathematical ability is, at the highest level of achievement. Some great mathematicians came from lowly backgrounds. Newton was the son of a yeoman farmer; Carl Friedrich Gauss, the son of a gardener; Pierre-Simon Laplace, the son of a parish official and cider merchant. Others came from professional backgrounds. But of the 28 mathematicians of all time described by Bell, beginning with Zero in the 5th century BC, where ancestral information is available, it shows that there is hardly a trace of mathematical achievement to be found in any of the fathers and close relatives.
