Every moeba, and where it came from

Who descends from whom, in one graph of the whole population. Founders sit at the top; each birth hangs from its two parents. Point at any moeba to light up its ancestors and descendants, click it to read about it, and choose a founder above the graph to look at one family at a time. Or turn it on its side: the time river runs along the ledger, every founder a source and every band the share of all births that descends from it.
