One wonders if Neanderthals, Homo sapiens, denisovans and homo erectus might have at one time been nodes on a system of ring species, that is to say each of these populations have neighboring populations with whom they could interbreed. Genes could flow from one node through one or more neighboring, intermediate populations to reach any other other node. But some of the nodes might not directly interbreed.
