Abstract
Simple treatments with hormones could unlock the expression of complex phenotypes not known to occur in nature. Using this method, Kim et al. recently obtained males from all-female populations of water fleas. The novel characters revealed by this work can be used in taxonomic identification and phylogenetic inference. Additionally, these ‘resurrected’ males offer insights into the conservation of traits that are not exposed to natural selection.
