LAF - not to get serious in a quirks thread, but might he have the freedom to combine the two topics? There's lots of great possibilities, such as what we know about where humans originated from and migrated to, based on genetics of populations - where did the Inuit come from, how do we know they crossed the Bering Strait during an ice age, etc. Or unique health and disease patterns in the Inuit that relate to shared genetics? Or to get really serious, issues that genetically-isolated populations have with researchers loving to use them as guinea pigs for all sorts of genetic-tracing studies, and maybe how this kind of research can be done well to benefit the health and well-being of the studied population? I could go on - as you can see, I love genetics too!
