cormorant, cormorants

Cormorants seem to be a very ancient group, with similar ancestors reaching all the way back to the time of the dinosaurs. In fact, the very earliest known modern bird, Gansus yumenensis, had essentially the same structure, although it was not a cormorant per se. The details of the evolution of the cormorant are mostly unknown, today. Even the technique of using the distribution and relationships of a species to figure out where it came from, biogeography, usually very informative, does not give very specific data for this probably rather ancient and widespread group. However, the closest living relatives of the cormorants and shags are the other families of the suborder Sulae - darters and gannets and boobies -, which have a primarily Gondwanan distribution. Hence, at least the modern diveristy of Sulae probably originated on the southern hemisphere.
