HOW AND WHEN DID OLD WORLD RAT SNAKES DISPERSE INTO THE NEW WORLD?

Frank T. Burbrink and Robin Lawson
2007. Molecular Phylogenetics and Evolution 43: 173-189

I read through it quickly. There are some interesting things to discuss. They pick the Bering Strait as the migration Route (the usual choice).

They have Coronella as the nearest relation to the new world lampropeltines.

They have separated bella from Elaphe.

They have not put frenata and prasina in Gonyosoma (that's going to be a bone of contention).

They put the fox snakes into a branch with the pits.

They put Bogertophis into a branch with the king snakes and their kin.

Very interesting (and provocative).
Regards
John
