Dr. Kammerer's Ciona Experiments

Abstract

IN NATURE of May 12, p. 639, Dr. Kammerer wrote: “Not content with any of the previous experiments [made by himself on the inheritance of acquired characters], I carried out, before 1914, what may really be an experimentum crucis,” and Dr. Kammerer states that when the siphons of Ciona intestinalis are cut off they regenerate longer than they previously were, repeated amputations giving very long tubes, and that the offspring of these individuals have siphons longer than usual.
