I recently talked to a guy in a lab at UCSD who said they had tried to look in other species (I thought it was just the lab rat) and came to the conclusion that the tandem repeats were just in vole and the chimps.  
 
I guess the STRs are in plenty of species, but to no effect. I wouldn't say this necessarily degates the Larry Young work, it just means mating behavior is more complicated across the Class Mammalia than maybe Young was hoping for (whoop-see!). 
 
All in all: two points each for positive and negative controls.
