Vargas et al. (2009) takes a new look at the controversy surrounding Paul Kammerer's work on midwife toads, eighty-four years after Kammerer's suicide, and proposes a possible mechanism to account for Kammerer's results. See also Wagner's (2009) editorial in the same issue of the Journal of Experimental Zoology Part B: Molecular Development and Evolution, and Pennisi's (2009) commentary in Science.
