  In a previous paper, we showed that the orientable cover of the moduli space
of real genus zero algebraic curves with marked points is a compact aspherical
manifold tiled by associahedra, which resolves the singularities of the space
of phylogenetic trees. In this draft of a sequel, we construct a related
(stacky) resolution of a space of real quadratic forms, and suggest, perhaps
without much justification, that systems of oscillators parametrized by such
objects may may provide useful models in genomics.
