   • In wild-type spermatids, Hrb is associated with the cytosolic surface of proacrosomic transport vesicles that fuse to create a single large acrosomic vesicle at step 3 of spermiogenesis. 2001 November 16, Ningling Kang-Decker et al., “Lack of Acrosome Formation in Hrb-Deficient Mice”, in Science, volume 294, number 5546, →DOI, pages 1531–1533:
   • Expanding the introductory section to include definitions of indirect and direct development and generalized descriptions of spermiogenesis, oocyte maturation and cytological organization, and fertilization would also help de-mystify these subjects for many readers. 1998 June 19, Richard Emlet, “Developmental Diversity”, in Science, volume 280, number 5371, →DOI:
