Abstract.--Stochastic modeling of phylogenies raises five questions that have received varying levels of attention from
quantitatively inclined biologists. 1) How large do we expect (from the model) the ratio of maximum historical diversity
to current diversity to be? 2) From a correct phylogeny of the extant species of a clade, what can we deduce about past
speciation and extinction rates? 3) What proportion of extant species are in fact descendants of still-extant ancestral species,
and how does this compare with predictions of models? 4) When one moves from trees on species to trees on sets of species
(whether traditional higher order taxa or clades within PhyloCode), does one expect trees to become more unbalanced as
