abstract = {Among tetrapods, viviparity is estimated to have evolved independently within Squamata (lizards and snakes) more than 100 times, most frequently in species occupying cold climate environments. Because of this relationship with cold climates, it is sometimes assumed that many origins of squamate viviparity occurred over the past 2.5-4 million years during the Pleistocene-Pliocene glaciations; however, this hypothesis is untested. Divergence-dating analysis on a 733-species tree of iguanian lizards recovers 20 independent lineages that have evolved viviparity and among 14 multispecies groups 13 derived live birth prior to glacial advances (8-66 million years ago). These results place the transitions from egg-laying to live birth among squamates in a well-supported historical context to further examine the underlying phenotypic and genetic changes associated with this complex shift in reproduction.}
