Sir Arthur Keith FRS (5 February 1866 – 7 January 1955) was a Scottish anatomist and anthropologist. He was a fellow and later the Hunterian Professor and conservator of the Hunterian Museum of the Royal College of Surgeons of England.
A leading figure in the study of human fossils, he became President of the Royal Anthropological Institute. The latter role stimulated his interest in the subject of human evolution, leading to the publication of his book A New Theory of Human Evolution, in which he supported the idea of group selection.
Where others had postulated that physical separation could provide a barrier to interbreeding, allowing groups to evolve along different lines, Keith introduced the idea of cultural differences as providing a mental barrier, emphasising territorial behaviour, and the concept of the 'in-group' and 'out-group'. Man had evolved, he claimed, through his tendency to live in small competing communities, a tendency which was at root determined by racial differences in his 'genetic substrate'. Writing just after World War II he particularly emphasised the racial origins of anti-Semitism, and in 'A New Theory of Evolution' he devoted a chapter to the topics of anti-Semitism and Zionism in which he argued that Jews have survived by developing a particularly strong sense of community between Jews worldwide based around cultural practices rather than homeland, while applying the 'dual code' in such a way that perceived persecution strengthened their sense of superiority and cohesion.
He is also famous for discovering the sinoatrial node, the component of the heart which makes it beat, with his student Martin Flack in 1906.
He was born at Quarry Farm near Old Machar in Aberdeenshire , the son of John Keith, a farmer, and his wife, Jessie Macpherson. He eas educated at Gordon's College in Aberdeen.
