Sand flies and reptiles have been convenient vehicles as they spread around the world. We remember when we all used to live in Pangea, in much simpler times before we found our mammalian hosts. The travel was, quite frankly, very limited in comparison to today. We like to pride ourselves that we were already seasoned travelers by sand fly, and when the continents drifted apart we were able to take advantage of the seismic shift in travel opportunities. Although I haven’t been able to take tea with my cousins on other continents for a lamentably long time, it is good to know that we survived such earth shattering times and have prospered in many disparate locations.
