Siphon regeneration in Ciona

Abstract

IN 1923 Paul Kammerer summarised research which he claimed demonstrated the inheritance of acquired characteristics. Since the success of Mendelian genetics had already made Kammerer's work suspect a report of his lecture1 was followed by a long and acrimonious debate. The Kammerer case thereby became a cause célèbre in the biology of that decade. The controversy has recently been resurrected in a popular book by Koestler2 and has gained additional prominence from an internationally televised BBC documentary based on the book. This paper reports a failure to duplicate one of Kammerer's key experiments.
