Unrootedtreeman was fun to create. Back in the 1990s, phylogenetics felt like doing research on the frontier. I suppose it still is, but back then almost everyone new the same methods and so on. So you could put a joke in about Hennig86 and most people would get it . (Hennig86 was a DOS-based program with cryptic commands – instead of ‘exit’ or ‘end’ you wrote ‘yama’ to close program. Yama is the hindu god of death and rebirth…) No wonder we needed Unrootedtreeman!
