The bad news is that everybody has face mites. The good news is that these tiny cousins of spiders and ticks seem to be harmless for the vast majority of us. 
In this episode, entomologist and evolutionary biologist Michelle Trautwein describes how she and her colleagues collected face mite DNA from a variety of volunteers for a study published in the Proceedings of the National Academy of Sciences. The results of the study were surprising and further confirmed our current understanding of human migration through time.
Listen as we explore the lives of these close personal friends of ours, and learn how they may help us answer new questions about our own evolution.
