Evidence for Gondwanan vicariance in an ancient clade of gecko lizards.

| Summary: | Aim Geckos (Reptilia: Squamata), due to their great age and global distribution,
are excellent candidates to test hypotheses of Gondwanan vicariance against post-
Gondwanan dispersal. Our aims are: to generate a phylogeny of the sphaerodactyl
geckos and their closest relatives; evaluate previous phylogenetic hypotheses of
the sphaerodactyl geckos with regard to the other major gecko lineages; and to use
divergence date estimates to inform a biogeographical scenario regarding
Gondwanan relationships and assess the roles of vicariance and dispersal in
shaping the current distributions of the New World sphaerodactyl geckos and
their closest Old World relatives. |
