read me file for Rebbeck phylogeny. File contains the NEXUS input for the maximum parsimony phylogeny based on mitochondrial sequences of dog (Canis familiaris ), grey wolf (Canis lupus), coyote (Canis latrans) and canine transmissible cancer. Canine transmissible cancers were collected from 7 countries (Israel, Mexico, South Africa, Thailand, Kenya, Greece and Malaysia), for some cancers, non-cancerous host tissue was also collected (denoted by the letter h). Sequence data covers mitochondrial genes ATP6, COX3, ND4 and ND5. Questions should be directed to Austin Burt - A.Burt@imperial.ac.uk
