Our preprint “There and back again: the dynamic evolution of panarthropod germ cell specification mechanisms” was selected for highlighting as a preLight, which is a preprint highlight service run by the biological community and supported by The Company of Biologists. Here, a team of scientists regularly review, highlight and comment on preprints they feel are of interest to the biological community. Read the preLight article by Dillan Saunders on our work here.
