A recent article in [*Biology Letters*](http://rsbl.royalsocietypublishing.org/content/11/10/20150694) by [**Thomas Sanger**](http://www.anolisevodevo.com/Sanger_Loyola_webpage/Home.html), a former **MCZ** postdoc, resolves the evolutionary history of the penis. Sanger examined MCZ's precious collection of Victorian-era histological slides of tuatara embryos for his research, which concludes that the penis evolved just once in the common ancestor of mammals and reptiles.
