A stochastic Dollo model for lateral transfer

Abstract:

Lateral transfer, a process whereby species exchange evolutionary traits through non-ancestral relationships, is a frequent source of model misspecification in phylogenetic inference. Lateral transfer obscures the phylogenetic signal in the data — the signal of the taxa ancestry — as the histories of affected traits are mosaics of the species phylogeny and may conflict with the underlying phylogeny. We control for the effect of lateral transfer in a Stochastic Dollo model and a Bayesian se...
