A bit OT, but wrt cross-linguistic similarities - I've always imagined this list [1] would be the resource for language origin studies, and I have dug out absolutely no research to that effect. I'm sure there is some - this list was compiled - but not nearly as much as I hoped. In particular, this could explain many similarities that are usually ascribed to genetics, but are actually only there because of commonalities in environment.
