title: Does the speciation clock tick more slowly in the absence of heteromorphic sex chromosomes?
abstract: Squamates may be an attractive group in which to study the influence of sex chromosomes on speciation rates because of the repeated evolution of heterogamety (both XY and ZW), as well as an apparently large number of taxa with environmental sex-determination.
