An accurate account of the exciting lead up to the 1977 discovery of split genes and obviously, as indicated by the title, Arnold Berk's fine perspective review does not deal with the alternative hypotheses that then appeared. However, readers are left to conclude that the "original suggestion" of Gilbert is now backed by "considerable evidence," so that perhaps the alternatives are disposed of. We should not forget that, in step with Gilbert, Darryl Reanney in Australia was fostering a viewpoint for which "considerable evidence" has also accumulated [1].
