(March 2023) PREPRINT ALERT! A study three years in the making! Josh Hahn's paper on the evolution of retinal cell types is now online on bioRxiv. We generate and integrate data across 17 species to trace the evolutionary history of retinal cell types. One of the most exciting (and unexpected) findings is that midget retinal ganglion cells, the most abundant RGC type in primates descendent from cell types present in the mammalian common ancestor. Thus, they are not primate "innovations" as previously thought. We identify their orthologs in several species, including mice! Congrats Josh!
