Aaron P. Ragsdale is a population geneticist who develops and applies models connecting demographic history to genetic variation. A weakly structured stem for human origins in Africa by Aaron P. Ragsdale and others evaluates histories with long-lived structure and continuing exchange rather than treating all ancestral biological populations as completely isolated branches. This connects mathematical model choice to the interpretation of human ancestry. [ref]
