Hannah uses human teeth as a window into ancient human migration! As a child grows, teeth lock in the chemical signature of the food and water they have been drinking. The isotopes of two chemical elements, oxygen and strontium, differ between environments meaning a region (and the food and water from there) has a distinct chemical signature. Analysing these isotopes in human teeth can be used indicate where someone might have spent their childhood, and by looking at multiple individuals from an archaeological site, a picture of how people migrated in the past can be drawn.

Nicole depicts teeth as keys into a diverse universe of untold stories. Looking at a tooth, like looking through a keyhole, gives us an insight into what's happening beneath the surface.
