Abstract:
The topologies of gene trees that evolve along the branches of a
species tree need not match the species tree topology. As a result of
this discordance, when gene tree evolution is assumed to follow a
"multispecies coalescent" model, simple phylogenetic algorithms can
exhibit peculiar statistical inconsistencies in inferring species
trees. This talk will examine the statistical consistency under the
multispecies coalescent of several algorithms - based on consensus
trees, ranked gene trees, and the "minimize deep coalescences"
algorithm. A summary will be presented of the known consistency
properties of the various algorithms.
