Isotope study determines fish were more prominent in early Alaskans' diets

(University of Alaska Fairbanks) Ice age inhabitants of Interior Alaska relied more heavily on salmon and freshwater fish in their diets than previously thought, according to a newly published study. A team of researchers from the University of Alaska Fairbanks made the discovery after taking samples from 17 prehistoric hearths along the Tanana River, then analyzed stable isotopes and lipid residues to identify fish remains at multiple locations.
